Works good
I'm using this as a brake vacuum boost pump switch on a custom electric vehicle and it works perfectly. I saw other reviews mention that theirs chatters but mine doesn't chatter at all and works perfectly so far.

The switches do not work. Iโm on my third one.
Iโve got three of these switches so far none of them work! When I hook them up, itโll work literally for a split second and shut off. If I take my feed wire and put it to the side of the switch for ground, everything works good. This third switch. I have never installed it put an old meter on it And the only place it functions correctly is on the inside. The body will not let it go to ground. I put my own meter on it and it does not show anything at all. The Amazon listing give something for troubleshooting, but it goes right to something with air-conditioning not even pertaining to this switch. Very frustrated.
