I have a security system with door/window open alarms. One of the sensors got damaged and these spliced right onto the alarm unit meaning I don't have to replace the entire alarm. I only needed to replace the damaged sensor end. Saved me a bundle. Review: Reed Switch Kit Provides Good Value - These switches are in the closed position when the magnet is close and opens when the magnet is about 3/4" away. All five switches worked perfectly and the included double-sided tape made installation easy. ## Features - Product Name: Door Magnetic Sensor Switch - Sensing distance: 10mm-15mm - Product size: 29*15.5*9mm Wire length: 33cm - Sensing distance: 10mm-15mm Service life: 1000000 times - Working current: 0.5A/Working voltage: 100V (1-100V)/Maximum power: 10W ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YFBG27Y | | Best Sellers Rank | #26,547 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #5 in Garage Door Sensors | | Brand | Gebildet | | Brand Name | Gebildet | | Circuit Type | 1-way | | Color | Black-NC | | Compatible Devices | Security systems, home automation hubs, door lock systems | | Connector Type | Screw | | Connector type | Screw | | Contact Material | ABS | | Contact Type | Normally Closed | | Contact type | Normally Closed | | Control Method | Touch | | Control Type | touch | | Current Rating | 0.5 Amps | | Current rating | 0.5 Amps | | Customer Reviews | 4.1 out of 5 stars 104 Reviews | | Item Weight | 0.07 Kilograms | | Manufacturer | Gebildet | | Material Type | Acrylonitrile Butadiene Styrene | | Model | E332 | | Mounting Type | Door Mount | | Number of Items | 5 | | Number of Positions | 5 | | Operating Voltage | 100 Volts (AC) | | Operating voltage | 100 Volts (AC) | | Operation Mode | ON-OFF | | Operation mode | ON-OFF | | Part Number | E332 | | Switch Type | Magnetic Switch | | Terminal | Screw | | UPC | 781621382491 | | Unit Count | 1 Count | | Wattage | 10 watts | ## Product Details - **Current rating:** 0.5 Amps - **Connector type:** screw - **Brand:** Gebildet - **Material:** Acrylonitrile Butadiene Styrene - **Mounting type:** Door Mount ## Images ![Gebildet 5pcs Recessed Wired Security Window Gate Contact Sensor Alarm Magnetic Reed Switch Black, Magnetic Door Sensor, Normally Closed Magnetic Switch - Image 1](https://m.media-amazon.com/images/I/71csUmCakjL.jpg) ![Gebildet 5pcs Recessed Wired Security Window Gate Contact Sensor Alarm Magnetic Reed Switch Black, Magnetic Door Sensor, Normally Closed Magnetic Switch - Image 2](https://m.media-amazon.com/images/I/61-GDO6qIiL.jpg) ![Gebildet 5pcs Recessed Wired Security Window Gate Contact Sensor Alarm Magnetic Reed Switch Black, Magnetic Door Sensor, Normally Closed Magnetic Switch - Image 3](https://m.media-amazon.com/images/I/61Hp-0X88uL.jpg) ![Gebildet 5pcs Recessed Wired Security Window Gate Contact Sensor Alarm Magnetic Reed Switch Black, Magnetic Door Sensor, Normally Closed Magnetic Switch - Image 4](https://m.media-amazon.com/images/I/61p74WIFSrL.jpg) ![Gebildet 5pcs Recessed Wired Security Window Gate Contact Sensor Alarm Magnetic Reed Switch Black, Magnetic Door Sensor, Normally Closed Magnetic Switch - Image 5](https://m.media-amazon.com/images/I/61DMdR4JJvL.jpg) ## Questions & Answers **Q: Are you certain these switches are normally closed ? The picture of the light circuit indicates they are normally open, without magnet.** A: You are correct. Almost all of the reed switches on Amazon universally have the NO/NC descriptions backwards. Even the guy who responded to you about his RV steps was mistaken as his application would require a normally closed switch (ie. door opening and removing the magnet would allow the current to flow). I think the big misunderstanding is these vendors (and some people) think the "normal" position is with a magnet adjacent the reed switch. It is not. **Q: What color are these? Pictures suggest black, but description says white.** A: Mine came in black **Q: Can this be used in a 12v application? I wanted to use ground to trigger a negative input(car alarm application)** A: Yes, I am also using it for 12V lights. You limit is going to be the 0.5amp load. **Q: Are these waterproof or at least water resistant?** A: Yes . It is water proof . Just only wires connection for sensor ( over 10'' long) must be in dry area. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfectly and attached to my existing alarm without issue. *by G***N on 21 November 2025* Worked perfectly! I have a security system with door/window open alarms. One of the sensors got damaged and these spliced right onto the alarm unit meaning I don't have to replace the entire alarm. I only needed to replace the damaged sensor end. Saved me a bundle. ### ⭐⭐⭐⭐⭐ Reed Switch Kit Provides Good Value *by G***Y on 28 November 2025* These switches are in the closed position when the magnet is close and opens when the magnet is about 3/4" away. All five switches worked perfectly and the included double-sided tape made installation easy. ### ⭐ Wrong switch type, these are NO, not NC *by S***E on 22 April 2026* All 5 of these are Normally Open (NO), not normally closed. This is the exact opposite of what I wanted and now they're useless for my project.
