Question: Do I understand correctly that the switch can be set for both low and high pressure?
Document: People who complain about the switch don't know how to set up a simple installation and then blame the switch. These switches have to work with a pressure tank of sufficient volume or otherwise the pump will short cycle and you might damage the contacts on the switch. If your installation is set up correctly the switch will last for years.
Square D is a good choice, I just put it in and forget it once it is set up. This is the Low Pressure Cutoff model and that is the safe way to  go .
Seems well made.I bought this for my cistern set up.It controls a Wayne 1 HP. irrigation pump.Was easy to install and adjust. My only concern was with the low pressure contact lever on the side. Its a bit cheap but does the job.You must be careful not to push it too far or you can bend the sheet metal that holds it in.As usual, you have minimal rm. inside to run your wire but thats just the nature of these switches.
differance that it is set up for.If it would letyou adjust it more ,I would have rated it a five star.But in all it is a great switch and I would reccommend it highly to anyone .I will be buying more.
I have to replace these pressure switches on my well ever 3-4 years. The components corrode or get gunked up internally, and eventually I end up with no water when taking a shower. No big deal, it is part of living the rural life.All the ones I have picked up from the local hardware store required quite a bit of adjusting to get set at the 40 PSI 'on', and the 60 PSI 'off'. This one was set perfect out of the box!
It was great to find a pressure switch with a low cut off.I have had several irrigation pumps lose a prime for one reasonor another.
This pressure switch replaced one that had corroding terminals as well as pretty silty inside. I purchased this one because of the extra safety of the low-pressure cutoff. Wired up easily and the on/off pressures were easily adjusted. Just make sure of the on/off pressure you need for your application as there are several different models. This is a 40 on 60 off model.
This is a replacement. I wouldn't have anything but this switch. If there are any problems with our sprinkler system that causes more water to be used than our pump will supply, the pressure goes below 30 PSI and the switch shuts the pump off until it is manually reset and we know we have to find our problem. This switch is also good for a low producing well. When more water is drawn than the well produces, the pump is shut off.
I have used this type before and have found them to be great for my application. I use this type of pressure switch in the tropics and have found it to be a pump saver. With the low pressure cut-off function, when my tank goes empty it cuts the pressure pump off. This happens a lot in third world countries where you depend upon a city water system as your main source for water and you never know when they will cut off your supply.
Nothing special to write here other than this replaced my old cutoff switch (same brand) that had lasted many, many moons. We had a hard freeze and I didn't have this unit and the pipe it was attached to properly heated or insulated, and it just didn't seem to work after thawing it all out. No big deal. This unit seems better than my old unit b/c it has the low-pressure cutoff. I can't attest to how well that will work, but I can only hope.
Answer: yes
