## 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.

### ⭐ Switches that can't switch....
*by C***C on 13 September 2025*

Arrived with only the switches and no magnets making this useless. Also has a blob of solder on one of the switch cables so clearly this has been used, then returned without the full package and resold.
