low air pressure switch

[shootiniron]

Anyone know where I can get a new low air pressure switch, the one that tells the buzzer when to stop buzzing.My buzzer wont quit so I figure its got to be the switch.

Thanks!

Remove it and benchtest it with compressed air and an ohm meter. If you can't find one, I have one somewhere in my collection of old parts. Let me/us know how it goes.

can the low pressure switch be ajusted ? My buzzer will not stop till about 85# My running pressure is about 110#
But would like it to stop alarming before 85.

Your local heavy truck dealer should have what you need.
Most for commercial trucks kill the buzzer and/or light @ 60-70psi.

DOT says 60 psi. They can be real touchy about it too.
