This pressure switch will automatically turn your compressor on when the pressure in your air tank falls below a certain pressure and will automatically turn your compressor off when the pressure reaches max pressure, delivering a switch-free and worry-free onboard air experience.
The Viair pressure switch with 40A relay has been tested to last 10,000 cycles with proper maintenance and features clearly labeled lead wires with insulated 1⁄4” male push-to-connect terminals.

Problems with my compressor not turning on after 2 years. Customer service helped troubleshoot and discovered it was a bad pressure switch. A $30 repair rather than a few hundred for a new compressor.
