HornBlasters 90-120 PSI Pressure Switch

Max Load of 20 Amps & 1/8" NPT


3 reviews

An essential component for the operation of any 12-volt or 24-volt compressor, our 90-120 PSI Pressure Switch provides worry-free operation of your onboard air system. When the air pressure in your tank drops below 90 PSI, our 90-120 PSI Pressure Switch will automatically activate your compressor until it reaches the desired pressure of 120 PSI. Our 90-120 PSI Pressure Switch can be utilized for both 12-Volt and 24-Volt Systems and can handle a power load of up to 30 amps. 

We recommend purchasing a relay with our 90-120 PSI Pressure Switch when using it with an air compressor. By installing a relay you can alleviate the burden of the compressor from the pressure switch, ensuring an even longer lifespan!

very good service

The order was shipped promptly. The product installed flawlessly and worked great. The only bad thing about the whole thing is UPS lost my package and I got it 2 weeks later. This is no fault of HornBlasters I don't blame them. Otherwise I'm totally happy with my experience with HornBlasters



Awesome product, ordered Wednesday and showed up Friday
