Refrigerant Pressure Sensor / Switch: Description and Operation
The A/C pressure switch is located in the condenser outlet line where refrigerant is in a high temperature, high pressure liquid state. The switch will
sense abnormally high or low pressure, and open the circuit. This removes ground, and the compressor will stop running.
