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.

This switch is terrible! Worked for about 5 minutes, it stopped working and would not turn the vacuum pump on, I found out when I when to push the pedal and had not brakes. Beware, this is a huge safety risk.
