Required Pressure Switch. Also needed a new Hadley compressor which I bought. It finally worked like new again. I really like Hadley products. They are sturdy and well made.

Worked great. The last one died after a year, most likely because I plugged it in with the electrical connections down, which could have allowed condensation to settle inside the switch. This time I changed direction and hope for a longer lifespan.

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…
