The air compressor pressure switch is a guard-dog of sorts, safeguarding against potential catastrophes. It is tasked with ensuring that air pressure in the tank does not climb too high – a measure to protect the compressor from overheating and combusting. Without a functioning pressure switch, the compressor is vulnerable to dangerous pressures and temperatures.

Housed close by the air compressor tank, the pressure switch is composed of a pressure gauge and a switch. The pressure gauge is employed to ascertain the pressure held within the tank, while the activator switch turns off the compressor when the inside pressure reaches a defined height.

When the pressure reaches a certain level, the pressure switch has the power to trigger the compressor into action. If the air pressure drops down below a specific point, it will turn off. Conversely, when it surpasses a particular amount, the compressor is automatically reactivated.

When you look at an air compressor, the pressure switch is usually preset to operate 10 psi directly below its maximum potential – in other words, the compressor will stop running at 90 psi if it can typically provide 100 psi in air pressure.

Generally, once the air compressor tank experiences a pressure build-up that hits the cut-off mark, the appliance is turned off, remaining in this inactive state until the gauge drops to the restart pressure, upon which the switch will reactivate the compressor.

To maintain safety, it is essential to examine the pressure switch regularly. If it isn’t fully functional, the air compressor may become dangerously overheated and potentially combust. Therefore, the pressure switch is a key safeguard against catastrophic failure of the equipment.

Everyone who owns an air compressor should be aware of the pressure switch and understand how to check it. Should you not know the proper procedure, the owner’s manual for your specific model should provide pertinent instructions.
