Telemecanique Sensors 9013FHG54J59M1X Air-Compressor Pressure Switch, 175 psi Set Off, 40 psi Fixed Differential, 4-Way Flange, 2-Way Release Valve, Auto/Off Cut-Out Lever

The mount was different than the old generic one. There is one blind screw hole on the top you can use to mount it to your tank. I may try and re-mount it to the front of the compressor.The unloader valve I had to adjust so that the lever that actuates it would not keep depressing the valve needle. (Which would eventually make the tank turn back on due to the leak)Unloader valve is a compression type fitting not a quick disconnect, so if you need additional 1/8" compression fittings, you can get those at Home Depot for a couple bucks.

I bought this to replace the safety / pressure switch on an old 1941 Bendix Westinghouse 80 gallon air compressor. Having the multi port air fittings made it easier to plumb after attaching to a home made bracket. Having the adjustable pressure cut out is nice also. Try finding parts for a compressor that old... lol.

Item was delivered February 4 and installed February 5. As of today, March 8, the contacts are now sticking and the return window is closed. We could have bought 3 of the cheaper ones for the cost of this one.

Works great! Didn't burn out in two days like the cheap one

Thanks
