When the pressure drops When it reaches or rises to the rated recovery value, the disc resets instantaneously and the switch automatically resets, or in simple terms, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison to change The on-off state of the switch element achieves the purpose of controlling the measured pressure. The elastic components used in the pressure switch include single coil spring tube, diaphragm, bellows and so on. Common models of UE J400 series mechanical pressure switches: UE J402-126 Vacuum pressure switch-0.1-0MPa J400 series main models and features J400 type, single point output, internally adjustable J402 type, dual point output, internally adjustable J403 type, Three-point output, internally adjustable
