Air Pressure Switch 85-100 PSI 1/8"-27 NPT DC 24V 12V Air Compressor 100PSI DC

Worked great. Shut off 100. Turn on at 80

After installation it seemed the first few cycles it would not cut off until ~120 psi. After several air tank fills and empties the switch was much more accurate. Ends up starting at 86 psi and stopping at 104 psi. Good enough for me.

I have a harbor freight pancake compressor which had worked great for many years. Then suddenly it would intermittently not turn off popping my high-pressure relief. I needed one of these to fix it and now it works great again.

awesome

Just what I needed

So I have a stupid Porter Cable Pancake Compressor that has a a pressure switch that shut off at 150 lbs, same compressor is oil less, never buy an oil less compressor talk about junk. The piston ring is made of cardboard. So getting to this pressure switch. My compressor even after a new ring and cylinder quickly couldn’t reach the 150 lb preset on the factory pressure switch. A new ring only reached pressure of 150 3 or 4 times before it wouldn’t reach pressure and then would not shut off. Never would there be a reason for a 4 gallon compressor to need to reach 150 lbs., and it took forever to go from 120 to 150. A parts store wanted $40 for a switch that would shut off at 120 lbs. compressor not worth putting that much money into. Looked on Amazon found these. Now compressor working fine shutting off at 100 lbs. Which is all I need from it. This switch saved tool from junk yard.Only reason it’s not a 5 star is haven’t had it installed long enough to evaluate durability. By itself install a simple plug in, but was a bitch to access the location in my terrible PC compressor

As represented

This pressure switch worked perfectly to replace the broken one in my blue hawk air compressor from Lowe's. I had always wished the pressure switch could be adjusted to shut off at less psi on the compressor as it was stock. I didn't realize you could change the switch so easily and affordably, and this pressure switch now kicks off at 100psi which is what I wanted. Cheapie air compressors seem like they run all day long to try and pump up to 125psi, which isn't necessary for what most folks do with such a compressor. This unit was totally worth the price and came with a spare as well.
