​ Adjustable pressure switch for water pump Description The pressure switch is purely mechanical deformation that causes the microswitch to act. When the pressure increases, different sensing pressure components (diaphragm, bellows, piston) will deform and move upward. Through the mechanical structure such as handrail spring, the microswitch at the top end will be finally activated to make the electrical signal output. The setting mode of UE pressure switch can be divided
