Campbell Hausfeld Air Compressor Pressure Switch Kit, 100/125 PSI #01A936

Old Part Numbers: CW207576AV

Pressure Switch replacement, 100/125 PSI, 4-port, on/off switch with unloader valve.

Replace the pressure switch if the compressor no longer cuts in or cuts out at the designated pressure (PSI), if the unit doesn't turn on or off, or if there is an obvious air leak from the contacts or manifold.

If the small unloader (bleeder) valve on or under your switch leaks constantly AFTER the unit shuts off, don't replace this part, replace the in-tank check valve. Most pressure switches have a bleeder valve which has a 1/4" plastic or copper line routing to it.
