Refrigerant Pressure Sensor / Switch: Description and Operation
During Abnormal Low-Pressure Operation
If the refrigerant pressure falls, the pressure on the seal film is lost, and the force exerted from the stopper, guide head, high pressure disc and high
pressure internal lid to the low pressure disc decreases, and the low pressure disc rotates back, pressing the guide pin down and causing the moving
contact to be OFF.
