WebHow Does an Air Compressor Pressure Switch Work? The diaphragm in the air compressor switch controls the airflow in the compressor to regulate the power output. When the tank has been filled with enough pressure, the diaphragm deforms and stops air from flowing until the pressure drops enough and the switch allows airflow again. WebA pressure switch is a passive device since all it needs to function is the presence or absence of pressure. Diaphragm pressure compresses a calibrated spring.
