Fit perfect, works perfectly. The low pressure cut-off is a pump saver. Make sure your switch has that function.

All my fault for not seeing the fine print. I bought this to protect my lawn water booster-pump and thought I was buying a sensor produced by a trusted manufacturer. Now I’m required to stay by the pump and make sure it doesn’t burn up which defeats the whole purpose of the switch. Thought I was buying a trusted brand but received a switch made by a company that I don’t recognize or trust and is a subsidiary of a large Taiwan based holding company.FROM NOW ON I’LL READ THE FINE PRINT. It works so far but now l’m doing product quality control.

As found on arrival.I don't know if this was a return item that was resold as new but this is what I found.The box was rather ragged upon receipt. I would not know if it left shipping that condition or if that occured in the transport. Obviously the electrical connecting points are not spec.All four of the electrical connects were bent, 1 was bent further than the other 3. All 4 of the screw connections were exceptionally tight, the 4th, the screw head is deformed.I am a large guy with strong hands and grip, I am having some trouble loosening the 4th screw.I need the water well functioning or I would return it as is. Maybe I can salvage the switch.This is NOT Square D quality that I am accustomed.

This low-pressure cut off switch has single-handedly prevented my jet pump from running dry on multiple occasions now. If the volume from the water source drops too low, this switch will detect the pump is not putting out enough pressure (10 PSI below cut in) and stop making contact, thereby shutting off the pump.Considering pumps are not inexpensive nor are they enjoyable to install, I’d consider this switch essential to safeguard your investment.My one caveat is if you’re filling a large volume (such as a 3000 gal storage tank), be prepared to hold the switch down for a long time before it’ll hold pressure. You can also tape it down with electric tape which has worked well for me.

We’re in drought in South Texas, 4th year of 7 year cycle. Although my well is ok, I have burned up well pump without a cut off, not a cheap repair.I found that Square D is reliable and robust under our hot summers. Highly recommend.

I gave them 5 stars because at first they accidently sent the standard version instead of the low pressure shut off one, it was in the wrong box. But i let them know and they immediately sent a replacement with no questions and gave me free return. It was a legit name brand one too and worked perfectly. I would highly recommend
