Our HornBlasters Weatherproof Pressure Switch with 40A Relay is built to perform in harsh conditions and keep your air system running strong. Available in 90-120 PSI, 110-150 PSI, 145-175 PSI, and 165-200 PSI ranges, each switch is fully encased and sealed with weatherproof sealant to protect it against the elements. The built-in 40A relay makes installation simple and clean—no extra wiring needed.
This pressure switch automatically turns your compressor on when tank pressure drops to the lower limit and shuts it off when it reaches the upper limit—no guesswork, no hassle.

United StatesThe HornBlasters 110-150 PSI Weatherproof Pressure Switch with 40A Relay works great. Also, Hornblasters is a great company to deal with.
United StatesNeeded a small part which was still under warranty. The initial reply and later approval was within minutes and received part the next day. Could not whish for anything else! Purchase last year was same super quick experience. It is refreshing nowadays to find a company who really seems to care.
United StatesI received the product quickly and it works well
United StatesI've had HornBlasters horns on my last 2 trucks. I am very happy with the improvements they have made . I have the kit that goes where the spare tire goes with dual air tanks. Also have the remote button. I am very happy. Impressed with the output.
United Statespersonnel were very helpful in figuring out why my horns were not working . helped me figure out exactly what part i needed and didn't try to up sale me on things i didn't need. Part came in on time as promised and installed and works like new, almost blew my ears off
