Bad switch
Installed the switch and tested worked one time shut the pump off. Stuck in the open position, tapped the switch and the pump run and would not shut off. Now the switch is stuck in the closed position, so the pump is working all the time and over heating, you’re better off ordering a adjustable vacuum switch.

Works til it doesn’t, I’m on my third one..
I use it for a brakes on a cammed Silverado. I’m on my third one of these due to them failing, I get about a month of use then they fail to work all together. There does not seem to be a better option as the ones from summit have similar issues. My suggestion is buy several, and prepare for sudden brake failure at all times lol!

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.

Overall goof value for money
Lucky find. Pump works well, just takes a bit of time to build up pressure. Overall goof value for money

Unreliable
I installed this along with a vacuum pump to assist my brakes. I tried to adjust it and at some point, I gently removed the spring under the adjustment screw. The screw had a spec of solder holding three coils together. As I handled the spring it crumbled so I replaced it with the spring from an ink pen. That made adjustment much more sensitive which is obviously desirable. But all the while the switch would randomly stick in the off position and leave me inconveniently and dangerously without power to my breaks so once I get stopped, I have to get out and tap on the switch to get my vacuum pump to work.

Stopped at 14 vacuum, but need 18-22
Couldn’t get this to work in my custom Peale booster setup. Wouldn’t allow the pump to get in the range of 18-22. There is no adjustment as it is factory set. Pretty useless for my application.I’m still trying to find an adjustable switch.I will say that I like the theory of how it works. Easy to set up, but it just doesn’t shut off at the right point. Couldn’t find any helpful info from the distributer and found no contact info.I’d like one like this that achieves my requirements.
