Gardner Bender GSW-SK

16 amp current capacity

SPST momentary operation

Normally on when open

Brass and white finish

The Gardner Bender GSW-SK is a conventional electrical door switch with a 4.7 rating and a clear normally-on, momentary-off operating format. It is designed to control lighting through the opening and closing of a door, making it a practical choice for closets, utility spaces, and other installations where illumination should follow door movement.

Pros

• High stated current capacity
• Works with conventional doorjambs
• Turns lights on when opened
• CSA listed construction

Cons

• Specified for 125V AC
• Requires a rectangular jamb opening

Its most notable strength is the stated 16-amp rating at 125V AC. The SPST contact arrangement turns the light on when the door opens and interrupts it when the door closes, providing familiar refrigerator-style convenience. The brass plate and white switch button offer a practical finish for a visible doorjamb, while CSA listing adds a meaningful point of consideration for an electrical accessory.

Installation requires a doorjamb opening measuring 1¼ inches wide by 2¾ inches high and 2 inches deep. That requirement is significant: the switch is intended for a larger cutout than the slim pressure-sensitive cabinet models later in this guide. The supplied information also lists a ½ horsepower or 10-amp rating at 125/277V AC, so the full circuit still needs to be assessed rather than assuming every listed capacity applies identically to every load.

This is the strongest general recommendation for a reader who wants a traditional doorjamb switch and has room for the specified opening. It suits hinged or sliding doors where the button can be aligned with the door edge. Buyers should verify the jamb geometry, wiring arrangement, and local electrical requirements before installation, but its operating concept and broad current specification make it an especially versatile option.

Traditional Automatic Lighting Control

The normally-on, momentary-off design removes the need to reach for a wall switch. The light stays energized while the door is open and switches off when the door returns to its closed position, assuming the wiring and mechanical alignment are correct.

Capacity for Everyday Circuits

The listed 16-amp capacity gives this model more headroom for many ordinary lighting loads. Electrical load, voltage, horsepower limits, and local code still govern the final decision, so the complete rating should be checked before connecting equipment.

600-watt load limit

Spring-loaded switch action

Hinged or sliding compatibility

Mounting hardware included

The Lee Electric 209DN is a 600-watt door light switch with a 4.5 rating. Its basic purpose is straightforward: it controls a closet light according to the door position, saving energy and extending bulb life by reducing the chance that an unattended light will remain on.

Pros

• Straightforward automatic operation
• Works with two door styles
• Hardware supports installation
• Clear 600-watt specification

Cons

• Less information on voltage
• Contact rating details limited

We may earn a commission when you buy through this link, at no additional cost to you.

A major advantage is compatibility with both sliding and hinged doors. That broadens the range of everyday projects, including wardrobes, closets, and storage spaces where a small modification to the door position can determine whether the switch is usable. Mounting hardware is included, which helps make the installation more convenient, although the switch still needs to be positioned so the door physically engages it.

The supplied information does not give the same detailed voltage, amperage, certification, or cutout dimensions provided for some full-size models. The 600-watt limit is the main performance specification, so users should keep their connected lighting below that figure and verify any electrical requirements in the current listing or packaging before installation.

For a simple closet-lighting project, the Lee Electric 209DN offers an understandable operating principle, broad door compatibility, and a straightforward load limit. It is a good budget selection when a compact functional solution is needed without the extra cabinet-style features found in multi-packs. Users who require a listed amperage, specialized environmental rating, or exact jamb cutout should seek that information first.

One Switch, Multiple Door Types

Support for hinged and sliding doors makes this model practical in mixed spaces. The main installation task is aligning the actuator with the edge of the door so movement consistently opens and closes the circuit.

Useful Load Guidance

A stated 600-watt maximum gives buyers a recognizable benchmark for compatible lighting. Keeping the connected load within the product specification helps prevent the switch from being asked to handle a load it was not designed to accommodate.

3 amps at 125V

Single-pole momentary contact

Metal jamb box

UL requirements stated

The Leviton 1865 is a single-pole, single-circuit doorjamb switch rated at 3 amps and 125 volts. Its 4.5 rating reflects a generally favorable customer reception, while the metal push-button and metal jamb box give it a more substantial appearance than many small cabinet switches.

Pros

• Metal push-button construction
• Includes metal jamb box
• Wide stated temperature range
• Clearly defined electrical limits

Cons

• Lower current rating than leaders
• Single-circuit operation only

We may earn a commission when you buy through this link, at no additional cost to you.

Its normally-on, momentary configuration follows the same useful principle as other full-size door switches in the guide: the controlled circuit is energized while the door is open and goes off after the button is released. The stated operating temperature range of -40°C to 120°C is particularly notable for a product intended for varied environmental conditions.

The product information emphasizes that it is the only doorjamb switch meeting UL requirements, making certification a central selling point. At the same time, its 3-amp capacity is lower than the leading current capacities in this list. That limitation does not diminish its value for ordinary lighting, but it makes the switch less suitable for loads that exceed its stated electrical rating.

This model is best for readers who value a defined amperage, metal construction, and certification language over maximum capacity. It should suit closets, utility rooms, and light commercial-style installations where the connected load is comfortably below 3 amps. Exact jamb dimensions and wiring directions should be confirmed before cutting the opening or connecting the circuit.

Built for Defined Electrical Service

The 3-amp, 125V rating is easy to understand and compare. Staying within that limit gives the installation a clear operating boundary, particularly important when selecting among products with different contact capacities.

Metal Construction and Temperature Range

The metal jamb box and push-button create a durable-looking installation, while the stated -40°C to 120°C operating range covers many indoor and sheltered conditions. Material alone should not be treated as permission for exposed outdoor use.

The Hordion Cabinet Door Switch is a two-pack of compact, pressure-sensitive switches designed to activate or deactivate a circuit when a cabinet door opens or closes. Its 4.5 rating and included installation accessories make it an appealing option for wardrobes, wine cabinets, bookcases, filing cabinets, and RV closets.

Pros

• Two switches included
• Automatically responds to doors
• Screws and caps included
• Many cabinet applications

Cons

• No electrical load rating
• Limited to cabinet-scale projects

We may earn a commission when you buy through this link, at no additional cost to you.

Unlike the larger doorjamb models, this product uses a pressure switch that detects the position of the door. It can therefore control cabinet lighting without changing the door or drawer itself. The package includes two switches, four screws, and four plastic caps, giving the installer the basic pieces needed to mount the switches in suitable fixtures.

The primary limitation is the absence of a clearly stated electrical rating in the supplied information. Because these switches are installed near furniture and may interact with low-voltage LED systems, shoppers should verify compatibility with the lamp, power supply, and wiring method. The product is intended to switch a circuit rather than serve as a complete lighting system.

This two-pack is best for cabinet-scale automation where one location might need one switch and another installation needs a second. It offers an easier route to automatic lighting than modifying a conventional hinged door with a larger jamb switch. Confirm the required power type, wiring arrangement, and switch rating before installation.

Automatic Cabinet Illumination

Pressure sensing lets the connected light respond as the cabinet door moves. That convenience is especially useful in wardrobes and storage cabinets where a light left on would waste energy.

Complete Two-Unit Package

Two switches, four screws, and four caps provide a useful starter set. The white plastic housing is intended to blend into light-colored cabinetry, although appearance will depend on the installation surface.

We may earn a commission when you buy through this link, at no additional cost to you.

Its electrical flexibility is the defining feature. The supplied specifications identify 6-amp and 10-amp versions at 125/250V AC, giving buyers options based on the circuit and available product variant. The switch also uses a familiar doorjamb installation with a stated opening of 1¼ inches wide, 2¾ inches high, and 2 inches deep.

The white plate and white switch button should integrate neatly with painted trim, while the relatively high current options provide practical capacity for ordinary lighting circuits. Buyers must confirm which electrical version they are purchasing rather than assuming every listing represents the same final rating.

For a reader comparing full-size jamb switches, the Hazlet is a compelling all-around choice when a light-colored finish, flexible voltage handling, and strong customer feedback are priorities. Confirm the required cutout, selected current rating, and local electrical requirements before installation. Its compact product identity does not change the need for accurate alignment with the door.

Options for Different Circuits

Stated 6-amp and 10-amp options offer more flexibility than a single fixed rating. The correct variant must match the intended circuit, and the connected load must remain within the selected product specification.

Discreet White Installation

Matching white plate and button components suit painted door frames. The traditional push-button design also makes the operating behavior recognizable and easy to explain before installation.

Automatic reset operation

Black PC enclosure

The Black Cabinet Lamp Switch is a two-pack of compact automatic-reset switches with a 4.4 rating. It is designed for wardrobes, sliding cabinet doors, wine cabinets, wall cabinets, and bookcases, where opening the door closes the switch circuit and closing the door opens it.

Pros

• Two compact switches included
• Works with AC or DC LEDs
• Automatic closed-door cutoff
• Multiple cabinet applications

Cons

• Limited 40-watt capacity
• Specific to smaller lighting loads

We may earn a commission when you buy through this link, at no additional cost to you.

The stated capacity is 1 amp at 250V with control of light sources up to 40 watts. That makes the product more appropriate for low-power cabinet illumination than for a full room lighting circuit. It is also compatible with AC-powered or DC-powered LED devices, which gives it flexibility when paired with suitable lamp hardware.

The housing is made from PC and is described as fire-resistant, corrosion-resistant, and wear-resistant. Its compact dimensions of 1.3 by 0.9 by 0.4 inches help it fit into tight cabinet spaces, while the black finish may coordinate better with dark furniture than the white alternatives.

This switch is a practical choice for small cabinet-lighting projects, especially where a refrigerator-style automatic response is desired. The package includes two switches, four screws, and four caps. Users should not exceed the 40-watt limit and should verify that the chosen lamp and power supply operate within the stated electrical requirements.

Sized for Compact Cabinetry

The small rectangular body is easier to conceal than a full-size jamb switch. Its automatic-reset action responds directly to cabinet-door movement, removing the need for a separate manual control.

Useful LED Compatibility

Compatibility with AC- or DC-powered LED devices allows use with appropriate cabinet lamps. The electrical characteristics of the lamp and its driver still need to match the switch's 1-amp, 40-watt limits.

Cons

• Low wattage ceiling
• More units than many projects need

We may earn a commission when you buy through this link, at no additional cost to you.

Its most useful advantage is scale. One purchase provides multiple switches for several cabinets or closets, reducing the need to buy equivalent units separately. Installation can occur on a side panel without changing the door or drawer, while the stated compact dimensions of 2.05 by 1.97 by 0.71 inches help limit visual impact.

The kit is rated at 1 amp and 250V and can control light sources or appliances below 40 watts. This is a modest limit that suits cabinet lighting better than higher-demand room circuits. The operating principle energizes when the door is open and interrupts the circuit when the door closes, provided the switch is positioned correctly.

This kit is best suited to a property with several cabinet-lighting projects or a contractor who wants spare units available. For a single closet, a smaller two-pack may be more practical. In either case, the 40-watt limit should guide the selection of connected lamps, and the switch should be mounted where the door reliably engages its pressure mechanism.

Convenience for Multiple Doors

Eight switches are useful for a home with several wardrobes or for a commercial installation serving numerous storage spaces. The package supports a consistent automatic-lighting approach without changing each door.

Simple Side-Panel Installation

Mounting on the side panel limits modifications to the door itself. Accurate placement remains important because the actuator must respond consistently as the door opens and closes.

Cons

• Intended for indoor use
• No load capacity stated

We may earn a commission when you buy through this link, at no additional cost to you.

Its steel construction is powder-coated white, giving it a durable-looking finish suited to indoor trim. The normally closed contact keeps the circuit on while the door is open and turns it off when the door closes. That operating behavior makes it useful for closets, darkrooms, walk-in refrigerators, and other indoor spaces where automatic control is useful.

The kit supports both sliding and hinged doors and includes mounting hardware. It is explicitly described for indoor use, so it should not be assumed to be suitable for weather-exposed locations. The supplied information does not provide a specific voltage or current capacity, which makes verification of the connected load essential before wiring.

This is a strong recommendation for an indoor doorjamb installation where a complete metal kit and a known contact behavior are priorities. It lacks the explicit load ratings published for several alternatives, so buyers should confirm compatibility through the current product documentation. For a clearly specified indoor application, however, its construction and included hardware make installation planning easier.

Complete Jamb Installation

The kit includes a push-button switch, metal box, cover plate, and mounting hardware. That organization helps identify the main installation components before the jamb is modified.

Automatic Power for Indoor Spaces

A normally closed contact energizes the connected circuit while the door remains open. This makes the kit useful for closets, darkrooms, and walk-in refrigerator applications where forgotten lights are a concern.

125 and 250 volts AC

Corrosion-resistant construction

Door-opening activation

The NSI TA502 is an electric door switch with a 4.4 rating and a straightforward operating purpose: the connected light turns on when the door opens. It supports 125/250VAC and has a maximum current rating of 6 amps, providing a clear electrical envelope for compatible lighting loads.

Pros

• Corrosion-resistant construction
• Broad voltage compatibility
• Clear six-amp limit
• Simple on-when-open operation

Cons

• No door compatibility detail
• Exact cutout needs verification

We may earn a commission when you buy through this link, at no additional cost to you.

The most distinguishing specification is its corrosion-resistant construction, which makes it more versatile than the switches described strictly for indoor use. That does not automatically mean every exposed outdoor installation is appropriate, but it gives the model broader environmental potential for a user who needs a more resilient door switch.

The 1¼-inch measurement in the title suggests a compact jamb format, although the supplied information does not provide a complete mounting-hole diagram. The exact physical dimensions, actuator position, and required clearance should therefore be confirmed before work begins. Proper alignment is essential for reliable operation.

The TA502 suits users who need more environmental tolerance than a basic indoor cabinet switch but do not require the highest current capacity of the leading alternatives. It is a solid middle-ground option for closets, service spaces, and compatible utility applications. Confirm that the door can actuate the switch and that the connected load remains under 6 amps.

Broader Environmental Suitability

Corrosion-resistant construction expands the potential range of installations. The degree of weather exposure should still be checked against manufacturer guidance and local electrical requirements.

Clear Electrical Limits

A six-amp maximum at 125/250VAC provides enough information to begin planning a lighting circuit. The connected load must remain within the stated current limit.

The Edwards Signaling 502A is an all-purpose electric door switch with a 4.4 rating. It uses a normally closed contact to activate a light as the door opens, offering the familiar behavior expected from a mechanical door-actuated lighting control.

Pros

• Straightforward all-purpose design
• Normally closed operation
• Defined voltage and current
• Decorative ivory housing

Cons

• Limited to 120V AC
• Six-amp current ceiling

We may earn a commission when you buy through this link, at no additional cost to you.

Its electrical specifications are clearly stated: operating voltage is 120V AC, and current is limited to 6 amps. These figures help narrow the intended use to compatible lighting circuits and make comparison with other full-size doorjamb switches easier. The maximum current is lower than that of the Gardner Bender model but adequate for many ordinary lighting installations.

The product combines an ivory housing with a painted gold faceplate. It may work particularly well in finished interiors where neutral-colored hardware coordinates with trim or older electrical fixtures. Unlike the Garvin model, its description does not limit it specifically to indoor use, but that omission should not be interpreted as proof of outdoor suitability.

The 502A is a sensible option for readers seeking a simple, established door light switch with visible operating behavior and defined electrical ratings. It is less flexible than multi-voltage or cabinet-pressure models, but it offers a concise solution for standard 120V lighting. Buyers should verify mounting dimensions and door clearance in the current listing before installation.

Conventional Normally Closed Action

The normally closed contact allows the controlled circuit to remain active while the door is open. This creates a direct relationship between door position and light operation.

Simple 120V Circuit Planning

The stated voltage and current provide a clear basis for matching the switch to a lighting load. Loads requiring different voltage or greater current should use another model.

Buying Guide – How to Choose the Best Door Switch for Light

Choosing a door switch involves balancing the physical door design, the lighting load, operating behavior, and installation environment. The most useful product is the one that fits the opening, reliably engages, and stays safely within its stated electrical limits.

Match the Switch to the Door Type

A full-size doorjamb switch is generally more appropriate for a conventional hinged or sliding door because it installs within the frame and uses a button that the door physically activates. Cabinet and wardrobe pressure switches are usually narrower and mount to a side panel, making them useful where changing the door or frame would be inconvenient. Confirm whether the door swings or slides and whether there is room for a traditional jamb box before choosing.

Prioritize a switch explicitly compatible with the movement and geometry of your door, then verify the required clearance and cutout dimensions.

Understand the Electrical Rating

Door switches are rated by voltage, current, and sometimes wattage. The Gardner Bender is listed at 16 amps and 125V AC, the Leviton at 3 amps and 125V, the Garvin kit has no current figure in the supplied information, and several cabinet switches are limited to 1 amp and 40 watts. These figures are not interchangeable. Check the lamp, driver, circuit, and any connected appliance against the product specification.

Choose a model whose published rating comfortably covers the intended load, and do not infer capacity from wattage when the manufacturer has specified amperage.

Select the Correct Contact Behavior

Most products in this guide use normally-on or normally closed behavior so the light is active while the door is open. A normally-on, momentary-off SPST arrangement describes the same practical result: opening the door engages the circuit and closing it releases the circuit. Some product descriptions use contact terminology that can seem reversed, so read the operational sentence rather than relying only on the label.

Look for a description that explicitly says the light turns on when the door opens. This is usually the most useful behavior for closets and cabinets.

Check the Mounting Space

Some switches need a substantial jamb opening. The Gardner Bender and Hazlet both specify an opening 1¼ inches wide, 2¾ inches high, and 2 inches deep, while the cabinet switches use smaller bodies and mount to a panel. Measure the available space, account for the cover plate, and consider how the actuator will meet the edge of the door.

Avoid selecting solely by door type. Accurate dimensions and adequate clearance are essential for a switch that operates reliably every time.

Consider the Installation Environment

The Garvin kit is explicitly intended for indoor use, while the NSI TA502 is described as corrosion resistant for outdoor use. Materials, certifications, and environmental claims differ across the products, so indoor suitability should not automatically be extended to damp or exposed locations. For outdoor installations, review the complete product instructions, local code, and the switch's environmental specifications.

Choose indoor, damp, or outdoor suitability deliberately. Corrosion resistance alone is not the same as a complete outdoor installation rating.

Evaluate Package Size and Number

A two-switch package works well for a pair of cabinets or a single project with two contact points. The eight-piece kit is more appropriate for a home with multiple closets, a rental property, or an installer who wants spares. A single-switch kit may be enough for one conventional door. Buying more units than the project requires can add unnecessary complexity to installation.

Count the doors and control points before choosing a multipack. For multiple units, also check whether each location needs the same switch and compatible lamp type.

Confirm Included Installation Parts

Mounting hardware is explicitly included with the Lee Electric 209DN and Garvin jamb switch kit. The Hordion and black cabinet-switch packages include screws and plastic caps, and the eight-piece kit is accompanied by installation pieces. Included fasteners can simplify the job, but they do not eliminate the need to confirm screw length, hole placement, and the electrical connection.

Compare the included hardware with what your installation already contains. A complete package is convenient, but the correct fastener and wiring method still matter.

Compare Appearance and Finishes

Finish selection matters when the switch remains visible. The Gardner Bender combines a brass plate with a white button, the Hazlet uses matching white components, the Garvin kit has powder-coated white steel, the Edwards model pairs ivory with a gold faceplate, and the cabinet switches offer white or black plastic. Choose a finish that coordinates with the doorjamb, cabinet, or trim rather than sacrificing installation fit for appearance.

Treat finish as a final compatibility check after function, ratings, and mounting have been settled.

How to Use and Care for Your Door Switch for Light

Begin by disconnecting power to the circuit and confirming that the selected switch is compatible with the door movement, voltage, current, and lamp load. For a full-size jamb switch, compare the required opening with the frame dimensions and position the actuator so the door presses the button only when it reaches the intended open position. For a cabinet pressure switch, select an unobstructed side-panel location where the door closes the actuator.

Follow the wiring instructions supplied with the product and local electrical requirements. The listed switches are designed to interrupt a lighting circuit, so the conductors, connector type, enclosure, and grounding arrangements must suit the installation. Do not assume a particular wire color or splice method applies universally, and do not connect a load beyond the published rating.

After installation, operate the door slowly several times and confirm that the light responds consistently. The light should energize when the door opens and turn off when it closes, without flicker, unintended cycling, or excessive force on the switch. Periodically remove dust from the moving contact and inspect for looseness, discoloration, damaged wiring, or a door that no longer aligns properly.

Frequently Asked Questions

What is a door switch for light?

A door switch for light is a mechanical or pressure-sensitive electrical switch that activates when a door opens. It is commonly used in closets, wardrobes, utility rooms, cabinets, darkrooms, and walk-in refrigerators. Most models energize the light while the door is open and interrupt power when the door closes, reducing forgotten lighting and unnecessary energy use.

Will a door switch work with LED lighting?

It may work if the switch's voltage and current rating cover the complete LED lamp and its driver. The black cabinet-switch listing specifically supports suitable AC-powered or DC-powered LED devices, while other models use wattage, voltage, and current limits. Confirm the lamp configuration and driver output before connecting any LED fixture to a door switch.

How do I choose between a jamb switch and a cabinet switch?

Choose a jamb switch for a conventional hinged or sliding door when the frame has room for a standard switch box. Choose a compact pressure switch for wardrobes, cabinets, and other furniture where the unit can mount to a side panel. Jamb switches tend to provide more explicit electrical ratings, while cabinet switches are usually compact and limited to smaller lighting loads.

Does the light stay on after the door closes?

No, assuming the product is correctly wired, properly aligned, and operating normally. The models in this guide use normally-on or normally closed behavior so that the light is powered while the door is open. If a light remains on, check the switch position, wiring, actuator alignment, and circuit before assuming the product has failed.

Can one switch control several lights?

It depends on the total electrical load and how the lights are wired. A switch may control multiple fixtures if their combined current or wattage remains within its published rating and the wiring arrangement is appropriate. The 600-watt rating of the Lee Electric 209DN, for example, gives a more generous ceiling than the 40-watt limit listed for several cabinet switches.

Are door light switches suitable for outdoor use?

That depends on the specific model and the degree of exposure. The Garvin Door Jamb Switch Kit is explicitly described for indoor use, while the NSI TA502 is described as corrosion resistant for outdoor use. For exposed locations, check the complete product specifications, environmental instructions, and local electrical code rather than inferring suitability from the material.

How much space is needed to install a doorjamb switch?

The required space varies by model. The Gardner Bender GSW-SK and Hazlet SQ11302 specify an opening 1¼ inches wide, 2¾ inches high, and 2 inches deep. Other products may use different dimensions, and the listing does not always provide a complete cutout diagram. Measure the frame and review the current installation instructions before cutting any opening.

Why is my automatic door light not responding consistently?

The most common causes are incorrect actuator alignment, a door that rebounds or does not travel far enough, loose wiring, or a lamp load outside the switch rating. Inspect the moving parts and wiring, then test the door through its full movement several times. If the switch remains inconsistent, confirm the load and wiring against the manufacturer's instructions.

Final Thoughts on Choosing the Best Door Switch for Light

The Gardner Bender GSW-SK is the most versatile overall recommendation because it combines a 4.7 rating, a normally-on SPST design, a stated 16-amp capacity, and conventional doorjamb installation. The Lee Electric 209DN stands out as a budget-friendly choice with a 600-watt limit, hinged and sliding-door support, and included mounting hardware, while the Garvin Door Jamb Switch Kit offers a complete steel installation for indoor hinged or sliding doors.

The right decision should begin with electrical compatibility rather than finish or appearance. Confirm voltage, current or wattage, operating principle, and mounting space, then match the mechanism to the door's movement. Larger cabinet projects may benefit from a multi-pack, while a single conventional door usually calls for one full-size jamb switch with clearly published specifications.

Finally, check the current product listing, manufacturer instructions, included accessories, and local electrical requirements before buying or installing. Ratings and product information can evolve, and prices and availability change over time, so the current listing should be the final source for purchasing decisions.
