The Viair 110-150 PSI pressure switch with 40A relay is a rugged and easy to install pressure switch that has a 40 amp relay built-in to increase longevity and decrease install time. The Viair 110-150 PSI pressure switch with 40A relay will automatically turn your compressor on when the pressure in your air tank falls below 110 PSI and will automatically turn your compressor off when the pressure reaches 150 PSI, delivering a switch-free and worry-free onboard air experience.

The Viair 110-150 PSI 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.
