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. ## Frequently Bought Together - Gebildet 3 Sets NO/NC Black Magnetic Switch Wiring Recessed Door Sensor Hidden Window Contact Reed Switch for Access Control Replace Alarm System - Nilight - TR-05 2PCS 60 Inch 180 LEDs Bed Strip Kit with Waterproof on/Off Switch Blade Fuse 2-Way Splitter Extension Cable for Cargo, Pickup Truck, SUV, RV, Boat , 2 Years Warranty --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/387491319-gebildet-3-x-magnetic-door-sensors-black-security-door-window](https://www.desertcart.tn/products/387491319-gebildet-3-x-magnetic-door-sensors-black-security-door-window) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-24*
