Review: Work perfectly for a low power LED light string to automatically turn on/off via proximity on door. - Work perfectly. I used them in my under the stairs closet. I installed some LED light strings on the ceiling in the closet and installed this switch on the wall, wiring it through a MOSFET power relay. When you open the closet door the lights automatically turn on, and they turn off when you close the door. It seems like the lights are always on because as soon as you open the door its illuminated, but of course that's not the case. I didn't need 10 or 15, so this was the only listing I found that had only a couple for a good price. The magnetic sensors already being wired made installation a breeze.
Review: Perfect, I loved. - Perfect, I loved.

## 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.

### ⭐ Move Along, Move Along.
*by J***. on October 15, 2025*

These little switches caused me so much headache, because they just quit working out of nowhere. The voltage and amperage were well within specs. I bought six because I needed four. I wired them in first by just twisting the wires. They worked. I then soldered and heat-shrunk the connections. They worked. I mounted them to the doors and cabinet, but one of them didn't work. I replaced it, and one of the others quit working after a day. I was convinced for a while that something was faulty with my wiring or mounting. Turns out these are junk.
