The working principle of the pressure switch: when the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor will move instantaneously, and the switch connector will be connected or disconnected by connecting the guide rod. When the pressure drops to or rises to the rated recovery value, the disc will reset instantaneously, and the switch will reset automatically, or simply, when the measured pressure exceeds the rated value, the free end of the elastic element will move, Push the switch element directly or after comparison to change the on-off state of the switch element to control the measured pressure. The elastic elements used for the pressure switch include single-coil spring tube, diaphragm, diaphragm box, bellows, etc
