I just installed blinking LEDs and buzzers in my dash and I am looking for around a 3 psi switch I can hook up to my fuel pumps so if the pressure drops to 3 psi or lower that it completes the circuit and trips the led and buzzer. Any ideas where I can get something like this? I have done some looking but not having much luck finding anything.

Thanks

Summit or Jegs

Looked at all the different marine super stores but never thought about looking at Jegs or summit. Thanks!

Now before I pull the trigger I need a second opinion.....

I think this is what I am looking for

What I want to double check on is that it sounds like at 5psi and higher the switch is open and at 4 psi and lower the switch is closed. Does that sound right?

I have 2 in the box ready to ship that are adjustable. Interested?

Thanks everybody, I know have several locations to buy them from. I am still wondering about wheter I need a normally open or normally closed? Based on my post above it sounds like I want one that is normally closed which means below 4PSI the switch is closed and above 4 it is open? Sound right?

ok, so I just read the documentation and maybe I need a normally open instead. It sounds like the nomally closed are a closed circuit when above 4 PSI and when below 4PSI it opens the circuit.

Yes normally open means when things are going good the circuit will be open (no continuity) when switch fails to achieve proper pressure the switch closes and creates the continuity loop and lights your dash light and or buzzer.

Great, thanks man!

What's the psi range? Are they normally open? How much?

Thanks
