Rated 5 out of 5 by from Easy to install... But did have to adjust I have a 10-12 year old Kobalt 60 gal compressor, pressure switch went bad on (wouldn't cut itself off at 155 psi). This is the only 125 on/155 off switch I could find. It installed easily, just had to bend/re-route 1/4" line going back to head. Now my only complaint, it's rated to shut off at 155 psi, when I installed it, it shut off around 165/170, kicked back on at 145. The pressure relief valve opens at 175, and that's too close for me. Now they claim these are "non adjustable" but there is a screw with arrow pointing left (-), and arrow pointing right (+). They have a dab of hot glue on the screw to keep you from adjusting it. I Simply peel the glue off with my finger and back the screw 3 full turns, now it kicks on at 120 psi, kicks off at 150 psi. Just use caution and common sense, you can adjust the pressures.

Rated 5 out of 5 by from Good replacement Wasn't sure it would work on my unit, but it hooked up without any issues and is working great.

Rated 5 out of 5 by from Piece of cake I read the above poor review and was skeptical that it would work for me but I needed one on a Sunday so I purchased it. I replaced a Furnace switch and the replacement was straightforward. I too had screw lugs on the old switch. This switch does have 1/4 tabs but if you loosen the phillips screws you can remove them and replace them with your original wiring lugs. I suggest the above reviewer call a professional to install. It was too obvious that the tabs could be removed for the lug connectors.
