THE KIND OF PRESSURE YOU CAN HANDLE. 

The Viair 40 amp air compressor 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. 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.

    Worked great with correct part

    We ordered the horns and they were delivered remarkably fast. But when we installed we couldn’t figure out why they weren’t working. Once we received the correct pressure switch and finally had time to make the change the horns are literally a blast… lol

    Works as it should for years.

    I've had a hornblasters kit since 2008. I've only had to replace two of these since. They reliably work for years under harsh conditions (under a truck)
