This HornBlasters pressure switch is essential to the operation of any 12 or 24-volt air compressor. The switch turns the compressor on automatically and shuts the compressor off automatically depending on the pressure in the tank. For example, the 110-150 PSI pressure switch would kick the compressor on anytime the system is at 110 PSI or below. And as soon as the system reaches 150 PSI it will shut the compressor off.

This pressure switch is rated for both 12 and 24-volt applications and up to 20 Amps.

We recommend purchasing a relay with this 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!

Excellent Service

Phone tech stayed on pho e while I was under the truck helping me diagnose the problem. It was like he was there with me. It was a $25 pressure switch. Ordered, received and honking my *** off again. Great service and great horn. Also scares Canada Geese lol


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
