Great brand, great switch
Needed a replacement for the probably 50+ year old cutoff switch that was installed on my compressor. This one screwed right into my setup and it hooked up in line with my 240v motor and it works great. The plastic cover is a nice upgrade from the coverless one with exposed wiring someone had just left on my old one.

perfect
Bought this to fix a Saylor Beall compressor I bought used years ago. The pressure switch was bent and did not shut off the compressor. This was a bolt on fix that worked perfect. Worked perfect out of the box and I have zero issues.

Quality switch, required significant adjustment.
I purchased this switch to replace the second failed factory pressure switch on my 4 year old DeWalt 80 gallon 175 psi 240v compressor The square D switch is an obvious quality improvement over the OEM sourced switch, with much more robust contactors and mechanisms My only gripe is the pressure cut in and out settings were way off upon installation the high pressure cutoff setting out of the box allowed my compressor to get to 220 PSI before I cut the power and turned it off. I was able to adjust this down to 175 PSI, however the cut in pressure setting is as low as I can adjust it, and it is at 150 PSI, not 135. I can live with it as is, and am hopeful this switch will last longer.
