## Questions & Answers

**Q: What is the magnetic gap (distance) at which these will close contacts?**
A: The switch I have will work up to 1 inch away.  This is measured with both pieces flat on a table and moving them apart until the reed switch stops seeing the magnet.

**Q: Will these work to turn on/off LED light strips?**
A: They should.All depends how you would set them up.The switch is normally used on doors and windows.

**Q: What wire is recommended for use with this? Looking to wire up a light in my small toolbox.**
A: 18 AWG Wire

**Q: can i use this for 110v?**
A: Not directly. You will need a relay that reduces the power going to the magnet. My experience is that even with 12v power supply, if the power is more that 500ma, this switch will fail. They work great, just not rated to take much current.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Half worked
*by T***M on June 3, 2023*

Only one of the two worked. One was shipped broken.

### ⭐⭐⭐⭐⭐ Great switch - Used to create wired switch for garage door
*by M***T on July 21, 2023*

I purchased this to make my own wired open/close detector for my garage door opener. The ability to use this both as a Normally Open or Normally Closed switch is great because I wasn't sure what mode I needed to have for my plan to work. So far it has worked flawlessly for me.

### ⭐⭐⭐⭐ It will not melt if you use it right.
*by K***Y on January 1, 2024*

I found this magnetic switch and it was more-or-less perfect for my application, but I couldn't help but notice all of the reviews of melted units. On further inspection you'll notice that many of these reviews detail misuse of the product by passing far too much current through it, for example to a lightbulb. This item uses a lightbulb as an example but explicitly says it should run to some sort of panel. This is a switch meant for powering a relay that can actually handle the current of your application. This is a switch for a signal, not for power. This will work great for something like an Arduino, but it will not for powering truck lights. Be warned that this is totally a Chinese wholesale product and you probably cannot pass through as much current as it says, but using it modestly will yield the intended result. Realistically you should not pass through 0.5A. You don't need much for a signal.
