This 1/8" NPT pressure switch with preattached wires and weatherproof coating is essential to the operation of any 12 or 24-volt air compressor. The switch turns the compressor on automatically when your pressure drops below a specific pressure and then off again once you reach the max pressure.

This pressure switch is rated for both 12 and 24-volt applications making it perfect for automotive or marine use. The switch is rated for 10,000 cycles and is extremely durable.

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!

Thanks hornblasters team

Called them up told them what was going on. They sent me a part: not only did they make sure I was being sent the right part. He had me take a picture under the truck and email it to him.( because I didn’t know what to look for) btw they didn’t get off the phone for this. He waited patiently. 10/10 for me on customer service. What’s awesome is their products are great products but what’s better is their customer service. I’m really happy with these guys
