Do I understand correctly that the switch can be set for both low and high pressure?

Pressure preset range of 20 psi is adjustable to a higher or lower setting from 40 to 60 to like 30 to 50 by turning the main screw #1. The range low & high can be adjusted by turning screw #2. Full instructions are shown on the inside of the pressure cover.

High and low pressure settings come pre set from the factory for a given range such as 20/40 or 40/60. That being said either of these pre set pressures can be adjusted by use of 2 pressure adjustment spring loaded screws. There is a limit to the adjustment so you should purchase a switch that is pre-set closest to the pressures needed or wanted for your system. Remember if your system has a bladder type expansion tank the air pressure will need to be reset in the bladder if you change the low pressure setting on your pressure switch. I hope this is beneficial.

Yes. The delta between them is preset. All you deal with is the high side. If you wish to deal with the low side there is a separate adjuster.

Yes, a 3/4 pump has pressure settings, you can adjust your settings to where you need them on your pressure switch.

No, as long as you can access the wiring as the pressure switch is controlled by an electrically plugged in module that becomes the switch. Unless your handy with electrical, you may need an electrician.

Depends how high. These switches usually maintain a differential of 20 - 30 psi. ie Low cut out 30, High cut out 50psi. I'v had mine set to cut out at 70psi if that's any help. I did reduce it to the 30 -50 range as in the summer here it easy to blow the pvc pipe. I think max for a water heater is 70psi.

Hi. My take on this switch, which I have been using in my system literally for decades, is that it is not picky about voltage. It works just fine for me as a pressure switch for my 24volt dc pump.

It works well providing you set it up right. To trigger the switch it needs to go past 90 degrees either way. Its heavy duty and has been reliable for me. I use mine to maintain my pool. I would say yes its a good choice.

The switch has two sets of contacts. You can use a single set of contacts for 120v or both sets for 240. It has a ground lug on the body. It is meant for simple 3 wire (2 wires with ground) pump. It's just a water pressure operated relay. Be sure to check and adjust the actual pressure it's operating at, I had to. The pressure number on the box is just the factory pre-set.

Not exactly. A switch is on or off. This is a variable resistor. The resistance changes with pressure sending more or less voltage to the gauge thus showing more or less pressure. (more or less voltage)

my thought is it will overload the capacity of the switch. both pumps would be on at the same time so I believe that will be too much. look at pumps wattage draw compared to specs of switch. good luck.

Yes it can. It sets in increments as you know. Just hold the set button until it starts blinking, then continue to press the down button until you reach the desired psi. Turn the switch on off and then on. It should start. Good luck.

It should work well. It is controlling the switch for two locations for our compressor.

This is precisely the reason I purchased this pressure switch. I had one that was set to 30-50 and I wanted to raise my house pressure to 40-60 and this pressure switch worked just fine. I have a Goulds 5GS07412 at 275 feet below the surface. I think this is a 1/2 hp.

it is a combination of up and down settings on the 4 switches. each switch has an up and down toggle position.

That is pretty low for a high pressure cutoff. Numerous youtube videos describe how to adjust pressures on these. Turning the nut with the small spring counterclockwise should reduce high pressure cutoff, but you'll need to also adust the nut with the large spring to change the range so that the unit will still turn on at a lower cut in pressure. Probably someone will have a more definitive answer.

switch has three ports, tank, gauge, outlet to hose coupler etc., also has unloader (see compression fitting on picture). Used on a 2HP motor, works great , you can order turn on/ turn off pressure but it is adjustable.

Most likely the answer is no. Pressure switches are relatively inexpensive you might want to "jury rig" something up..

Yes. Switch operates on pressure build up in tank. Doesn't care what type pump. The contacts are separate to control the two hot wires. When you restart circuit, you may need to hold the priming lever down until pressure builds up the first time. Be sure to remove power from circuit before you work with it, each wire usually is 120 volts and 240 between the two.
