We’ve all been there—opening a dark pantry, fumbling blindly for a light switch, or squinting into a cluttered wardrobe trying to find that one shirt buried in the back. It’s frustrating, time-consuming, and honestly, unnecessary in today’s world of smart, convenient home solutions. Whether you’re upgrading your kitchen cabinets, organizing a jewelry armoire, or simply tired of stubbing your toe in a dimly lit closet, there’s a better way. And it doesn’t require rewiring your entire house or hiring an electrician.

Enter the 4 pcs Cabinet Door—a compact, cleverly designed switch that automatically turns your cabinet or closet lights on when you open the door and off when you close it. At just $9.59 for a pack of four, this unassuming little device has earned a solid 4.4-star rating from nearly 900 customers, and for good reason. It’s simple, effective, and incredibly versatile. In this in-depth review, I’ll walk you through everything you need to know about the 4 pcs Cabinet Door—from how it works and where to use it, to real-world performance, customer feedback, and whether it’s worth your money.

What makes the 4 pcs Cabinet Door stand out isn’t just its affordability or ease of installation—it’s the way it solves a common, everyday problem with elegant simplicity. No apps, no Wi-Fi, no complicated setup. Just a mechanical switch that responds to the motion of your cabinet door. Whether you’re powering LED strips, puck lights, or small bulbs, this switch integrates seamlessly into your existing lighting setup. And with support for both AC and DC power (12V, 24V, and even 110V), it’s compatible with a wide range of lighting systems. Let’s dive deeper into what this little switch can do.

What is the 4 pcs Cabinet Door?

The 4 pcs Cabinet Door is a set of four normally closed (NC) magnetic reed switches designed specifically for cabinet and closet lighting automation. Each switch is engineered to complete an electrical circuit when the cabinet door is opened (activating the light) and break the circuit when the door is closed (turning the light off). This means you get instant, hands-free illumination exactly when and where you need it—no switches to flip, no timers to set, no motion sensors to calibrate.

Each switch measures just 1.3″ x 0.9″ x 0.4″, making it compact enough to fit discreetly behind cabinet doors, under shelves, or along door frames without being obtrusive. The housing is made from high-quality polycarbonate (PC), a material known for its durability, flame resistance, and resistance to wear, rust, and corrosion. This ensures the switches can withstand the humidity of a pantry, the dust of a garage cabinet, or the frequent use of a bathroom vanity.

The switches are rated for 1 amp at 250 volts, which is more than sufficient for most low-wattage LED lighting setups commonly used in cabinets and closets. They work with both alternating current (AC) and direct current (DC) systems, including 12V and 24V LED strips, battery-powered puck lights, and even standard 110V household lighting (with appropriate wiring). This versatility makes them ideal for a wide range of applications—from kitchen pantries and wardrobes to tool cabinets, jewelry boxes, and even RVs or boats.

The package includes four white switches, eight screws for mounting, and eight plastic caps to cover the screws for a clean, finished look. The inclusion of mounting hardware is a thoughtful touch, especially at this price point. The white color blends well with most cabinet interiors, though it may stand out slightly in darker wood finishes.

Who is this product for? Homeowners looking to upgrade their storage spaces with automatic lighting, DIY enthusiasts who enjoy tinkering with home improvements, RV and boat owners needing efficient lighting solutions, and anyone tired of fumbling in the dark. It’s also great for people with limited mobility who benefit from hands-free lighting, or parents who want to make nighttime diaper changes or snack retrievals easier.

Key Features of 4 pcs Cabinet Door

✅ Normally Closed (NC) Design for Automatic Operation

The core functionality of the 4 pcs Cabinet Door lies in its normally closed (NC) configuration. This means that when the cabinet door is closed, the switch is open (circuit broken, light off), and when the door is opened, the switch closes (circuit completed, light on). This is the opposite of a typical light switch, but it’s exactly what you want for automatic cabinet lighting.

In practical terms, this design ensures that your lights only come on when the door is open—saving energy and extending bulb life. There’s no risk of accidentally leaving the light on, and no need to remember to turn it off. The switch responds instantly to the door’s movement, providing immediate illumination the moment you open the cabinet. This is especially useful in tight spaces where visibility is poor or when your hands are full.

I tested this with a 12V LED strip in my pantry, and the response was nearly instantaneous. The light came on the second the door cleared the frame and turned off the moment it clicked shut. No delay, no flickering—just reliable, consistent performance. This kind of responsiveness is crucial for a product that’s meant to improve convenience, not add frustration.

✅ Wide Voltage Compatibility (12V, 24V, 110V)

One of the standout features of the 4 pcs Cabinet Door is its ability to work with multiple voltage systems. Whether you’re using low-voltage LED strips (common in under-cabinet lighting), battery-powered puck lights, or even standard 110V household wiring, these switches can handle it—as long as the current stays within the 1A limit.

This flexibility is a huge advantage. Many similar products are limited to DC-only setups, which restricts their use to battery-powered or transformer-driven lights. But the 4 pcs Cabinet Door bridges that gap, making it suitable for both DIY LED projects and more permanent hardwired installations. For example, I used one switch with a 24V LED strip in my workshop cabinet and another with a 12V battery-powered light in my closet—both worked flawlessly.

Just remember: while the switch can handle 110V AC, you must ensure your wiring is safe and up to code. If you’re not comfortable working with household voltage, stick to low-voltage DC systems or consult an electrician. But for most cabinet lighting applications, 12V or 24V is more than sufficient and much safer.

✅ Compact and Discreet Size

At just 1.3 inches long and less than half an inch thick, the 4 pcs Cabinet Door switches are incredibly compact. This small footprint allows them to be mounted in tight spaces without interfering with the door’s operation or the contents of the cabinet. I installed one behind the hinge rail of a shallow pantry door, and it was completely hidden from view.

The low profile also means they don’t stick out or create bumps that could catch on clothes or dishes. In a wardrobe, for instance, you can mount the switch on the side frame or top rail, where it won’t interfere with hanging garments. The included screws are short and flush-mounted, and the plastic caps help conceal them for a clean, professional look.

This discretion is especially important in high-traffic areas like kitchens or bathrooms, where aesthetics matter. You want the functionality without the visual clutter. The 4 pcs Cabinet Door delivers on both fronts—effective performance with minimal visual impact.

✅ Durable, Flame-Retardant PC Material

The switches are housed in high-quality polycarbonate (PC), a thermoplastic known for its strength, clarity, and resistance to impact and heat. This material is commonly used in safety glasses, bulletproof windows, and electronic enclosures—so it’s more than capable of handling the demands of a cabinet environment.

PC is also flame-retardant, which is a critical safety feature when dealing with electrical components. In the unlikely event of a short circuit or overheating, the housing won’t easily catch fire or emit toxic fumes. It’s also non-toxic, rust-proof, and corrosion-resistant, making it suitable for humid areas like bathrooms or outdoor storage sheds.

During my testing, I exposed one switch to a damp environment (a basement storage cabinet) for several weeks. There was no sign of rust, warping, or degradation. The switch continued to operate smoothly, proving its resilience in less-than-ideal conditions. This durability ensures a long service life, even with daily use.

✅ Easy Installation with Included Hardware

One of the biggest selling points of the 4 pcs Cabinet Door is how easy it is to install. You don’t need special tools, electrical expertise, or a degree in engineering. The package includes everything you need: four switches, eight screws, and eight plastic caps. The screws are the right length—long enough to secure the switch but short enough not to protrude through the other side.

Installation is straightforward: mount the switch on the cabinet frame (not the door itself), position it so the door’s movement triggers the internal mechanism, and connect it inline with your lighting circuit. For LED strips, this usually means splicing into the positive wire. For battery-powered lights, you can insert the switch between the battery and the light.

I installed all four switches in under 30 minutes, including testing and adjustments. The instructions are minimal (mostly diagrams), but the design is intuitive enough that even a beginner can figure it out. The plastic caps are a nice touch—they hide the screw heads and give the installation a polished, finished appearance.

✅ Reliable Performance in Real-World Use

After several weeks of daily use across multiple cabinets, the 4 pcs Cabinet Door switches have proven to be reliable and consistent. I’ve used them in a pantry, a wardrobe, a tool cabinet, and a bathroom vanity—all with different lighting types and door styles. In every case, the switches responded accurately to the door’s position.

The actuation is smooth and requires minimal force. You don’t need to slam the door or open it fully for the switch to engage. Even a partial opening (about 2–3 inches) is enough to trigger the light. This is important for usability—nobody wants to wrestle with a stiff door just to turn on a light.

I also tested the longevity by opening and closing one cabinet door over 200 times in a single day (yes, I was bored). The switch showed no signs of wear or reduced sensitivity. This kind of durability is essential for a product that’s meant to be used dozens of times a day.

✅ Great Value for a 4-Pack

At $9.59 for four switches, the 4 pcs Cabinet Door offers exceptional value. That’s less than $2.40 per switch—including mounting hardware. Comparable products from brands like Lutron or Honeywell can cost two to three times as much for a single switch, and they often require additional components or professional installation.

Even when you factor in the cost of LED lights or wiring, this setup remains one of the most affordable ways to add automatic lighting to your cabinets. And since the switches are reusable, you can move them to different cabinets as your needs change. I’ve already repurposed one from an old pantry to a new jewelry box—no extra cost, no waste.

For the price, you’re getting a durable, versatile, and effective solution that solves a real problem. It’s hard to argue with that kind of value.

How Does 4 pcs Cabinet Door Perform?

✅ Pantry Lighting: Hands-Free Convenience

I installed one of the 4 pcs Cabinet Door switches in my kitchen pantry, which previously had no lighting. The space is narrow and dark, especially in the early morning when the overhead kitchen lights aren’t on. Using a 12V LED strip mounted along the top shelf, I wired the switch inline with the positive lead.

The results were immediate and impressive. Every time I opened the pantry door, the light came on instantly. No fumbling, no guessing where the cans are. I could see everything clearly—cereals, spices, snacks—without needing to turn on the main kitchen lights. When I closed the door, the light turned off within a second. No phantom glow, no wasted energy.

Over several weeks, the switch performed flawlessly. Even with frequent use (multiple times a day), there was no delay or malfunction. The compact size meant it didn’t interfere with the door’s swing, and the white color blended well with the painted wood frame. This is exactly the kind of use case the 4 pcs Cabinet Door was designed for—and it delivered.

✅ Wardrobe Lighting: Perfect for Closets

My walk-in closet was another prime candidate for the 4 pcs Cabinet Door. The existing lighting was a single overhead bulb that cast long shadows and made it hard to see colors accurately. I added a 24V LED strip along the top rail and installed the switch on the side frame, positioned so the door’s edge would press against it when closed.

The difference was night and day. Opening the closet door now floods the space with bright, even light. I can easily distinguish between navy and black shirts, find matching shoes, and see the texture of fabrics. The light turns off the moment the door closes, so there’s no risk of leaving it on overnight.

One minor adjustment was needed: I had to reposition the switch slightly to ensure consistent contact. But once aligned, it worked perfectly. The switch’s durability stood up to daily use, and the flame-retardant housing gave me peace of mind, especially with the closet’s proximity to electrical outlets.

✅ Tool Cabinet: Practical for Workspaces

In my garage workshop, I have a metal tool cabinet that’s often used in low-light conditions. I installed a 12V LED puck light inside and connected it to one of the 4 pcs Cabinet Door switches. The switch was mounted on the inside of the cabinet frame, triggered by the door’s movement.

This setup has been a game-changer. No more digging through drawers in the dark or using a flashlight to find a specific wrench. The light comes on the second I open the door and turns off when I close it. It’s especially useful when I’m working late or in the early morning.

The PC housing held up well against dust and occasional moisture, and the switch showed no signs of wear after weeks of use. The only challenge was finding a secure mounting spot on the metal frame, but the included screws worked fine with a bit of pre-drilling.

✅ Jewelry Box: Elegant and Functional

My wife’s jewelry box was the final test. It’s a small, elegant case with multiple drawers, and she often struggled to see her pieces in dim lighting. I installed a tiny 3V LED light inside one drawer and used a 4 pcs Cabinet Door switch to control it.

The result was delightful. Opening the drawer instantly illuminates her necklaces, earrings, and bracelets, making it easier to choose the right piece. The switch is completely hidden, so it doesn’t detract from the box’s appearance. She loves the added convenience, and I love that it was so easy to set up.

This use case highlights the switch’s versatility. It’s not just for large cabinets—it works beautifully in small, delicate spaces too.
