I installed this in a deep kitchen cabinet that I use all the time. The inside of that cabinet was dark enough that I’d sometimes need a flashlight to find what I was after. No more! Installed this switch to the top of the cabinet with Velcro, ran a few 12 volt jewelry spotlights across the top and down one side and voila! Perfect light in that cabinet as soon as the cabinet door’s opened.
I’d considered a magnetic switch, a push-button switch and a motion sensor switch. So glad I went with this Sensky sensor. If you need a simple switch for a 12 v device, this Sensky switch is a great option!
