## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect solution to a difficult problem!
*by D***1 on March 13, 2025*

Perfect solution to a touchy problem. The adhesive mounting tabs were perfectly suited to my application. I had to trim the back plate a little but rhat was no issue. The long wire leads were very helpful when mounting in tight spaces. I highly recommend these switches.

### ⭐⭐⭐⭐⭐ Small size and works nicely
*by J***. on January 6, 2025*

They work really well so far. (3 months) I was surprised on the range of activation. I was worried that it was going to require a super close fit, but they don't. I would say it switches off when within less than an inch or so. Very pleased.

### ⭐⭐⭐⭐⭐ Work Great!
*by D***E on September 5, 2024*

Used these to activate lighting (12v COB LED) inside a storage compartment so that lights were only on when the door was open. Spliced the wires in and it works flawlessly. I used the included adhesive mounting strips to position and test the position of the two halves of the switch on the door and frame. Secured more permanently with screws once I confirmed functionality but installation was easy and it’s a cool feature to add to a lighting project.
