Schematic diagram of differential pressure switch

The differential pressure switch is composed of two membrane box cavities, which are sealed by two sealing diaphragms and one differential pressure diaphragm. The high pressure and low pressure respectively enter the high pressure chamber and low pressure chamber of the differential pressure switch, and the felt differential pressure deforms the pressure sensing diaphragm. Through the mechanical structure such as the balustrade spring, the top micro switch is finally started to make the electrical signal output.
