A water pressure switch is commonly used to control a well pump. The switch is installed at the pressure tank and when water goes out of the tank pressure drops . When pressure gets to 30 psi that's usually the setting for the switch to activate the pump. The pump will come on and run for 2-5 minutes replenishing the tank to 50 psi then the switch will turn it off. (some systems are 40-60, but 30-50 is common)

Pressure switch does not switch off?
switch is frozen from water corrosion.
How do i maintain water pressure in my well?
with a pressure tank and pressure switch
How much pressure should a water bladder tank hold?
It depends on which pressure switch you have. The total pressure with a 60-80 switch is about 84 psi.
Where is the pressure switch in a well water supply?
The pressure switch is usually on the pump if it's a jet pump, or at the base of the pressure tank if a submersible pump.
How can you increase water pressure with a 36 gallon tank and 2040 pressure switch?
If your pump is capable of making more pressure than it is now, you can turn up the pressure switch.
What determine residential water well pressure?
The pressure is determined by the "pressure switch" typically located at the pressure tank. The switch monitors system pressure and will turn the pump off when the water pressure reaches a predetermined level. As water is used - drawn off the pressure tank - the switch will turn the pump back on at a lower pressure. Switches are typically 30-50 or 40-60 (contacts closing at the lower pressure setting and opening at the higher setting).
How do you pump up the pressure in a cold water tank?
residual air pressure in the tank, and the pressure switch settings
How much water pressure should be in a well water expansion tank?
The air pressure should be 2-3 psi LESS than the pressure switch cut on. If you have a good 30/50 switch, then 27-28 psi air is good. (this is measured when tank is almost empty of water.)Total pressure with this switch should never be more than about 58 psi
How much pressure should be put into a bladderless water tank?
You must drain the tank almost to bottom, switch off the pump and water feed to house . Now put in 27-28 psi of air if you have a 30/50 pressure switch. Put in 37-38 if you have a 40/60 switch. It may be necessary to adjust the pressure switch after observing cut in and out.
How do you change the water pressure on a home well?
Check the link for answers to a lot of questions on wells and pumps. The pressure switch is the device that controls what pressures the pump will turn on and off at. This is not to say that the pressure switch makes pressure. Pressure has to be made by the pump.
What does a tank do?
Water bladder tanks are tanks which contain a rubber bladder that is filled with either water or air. The majority of water bladder tanks have water-filled bladders. When a water faucet is turned on or a toilet is flushed, the water is piped in from the water tank. As the water pressure and air pressure get low, the contacts on the pressure switch click together. The pressure switch sends an electrical current to the water pump which causes the water pump to kick on and pipe water back into the water bladder tank. The amount of time it takes for the pressure switch to click on depends upon the size of the water bladder tank. The larger the water bladder tank, the longer it will be before the pressure switch starts to deliver electrical current to the water pump.

We have a well with a pressure pump. The water pressure is low all through the house and the water pressure pump is reading low. What is causing this. Can we fix it ourselves. Pump is only 7yrs old.?
You just need to adjust the pressure switch on the pump to your desired pressure...typically around 50 psi. Sometimes the springs in the pressure switch get old, and just need tightening.
