The differential pressure switch consists of two capsule chambers, two sealed diaphragms and one differential pressure film. High pressure and low pressure respectively enter the high pressure chamber and low pressure chamber of the differential pressure switch. The felt differential pressure makes the pressure sensing film deform. Through the mechanical structure such as handrail spring, the top microswitch is finally started to output the electrical signal.
