Review on H13940S Pressure Switch by Hadley Horns by Chris Laznovsky

Not sure why I gave it 2 stars instead of 1. I think because it worked for a while. I had a leak in my tank so I removed the tank, welded it on and reinstalled it. Light up the truck and the compressor won't turn off. Went to 160psi b4 I unplugged it. He wasn't even 3 months old and only used it for a couple of weeks. I unplugged the pressure sensor, put it in an ohmmeter and it didn't shut off until it reached 180psi. Rating 110-135. However. I ended up using their $35 Hadley switches. I will try a 16.88V push button switch. What's to lose if you try other than 1/2 the cost of Hadley.
