How Air Compressor Pressure Switch Work?

Air compressor pressure switches utilize airlines to monitor pressurized air as it travels to and from your air tank. All pressure switches have some part that reacts when pressure is used to it. The most basic device is a diaphragm that will physically compress when revealed to this air.

Air pressure in your compressor tank will develop and eventually build up enough backward pressure — also described as cut-out pressure — to improve the shape of this diaphragm. Deformation here will move the pressure switch.

When the air compressor pressure switch’s diaphragm is distorted enough, its movement will break connection inside the switch so that power stops running to the compressor’s motor circuit, stopping the compressor from pressurizing the air in your tank.

Constant air pressure at a particular volume will keep the diaphragm deformed. When the air pressure in your tank falls far enough, the diaphragm will revert back to its normal shape. Once this pressure — described cut-in pressure — lightens to a certain level, an inner operator within the diaphragm will deform differently. This action closes the circuit and starts the motor back up again.

Your Pressure Switches for Compressors maintains this dance as long as your machinery is utilizing compressed air. The cycle is broken when the system is no longer powered externally or when there is an issue. Exposures at any point in your compressor’s pressure switch and nearby casing can hold your work and cause significant problems.
