Single Pressure Controls

Single pressure controls help protect against refrigerant loss or excessive air conditioning/refrigeration compressor system pressure. A pressure switch closes an electrical contact when air compressor fluid pressure rises or falls. An air pressure switch is connected to a bellows or diaphragm that reacts to system pressure. The compressor’s press switch can automatically shut down the compressor when pressure gets too high, to prevent damage to the AC system.
