Old Part Numbers: FSPS115150
Air compressor switch for original equipment switches Furnas 69MB8LY, Huanli QSK-2, LeFoo LF10-1H3. Furnas/Hubbell type air compressor switch. 115/150 PSI, single 1/4" FPT port, 1/4" compression 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.
