Refrigerant Pressure Sensor / Switch: Description and Operation
High Pressure Cutout Switch
The system is also equipped with a high-pressure cutout switch. This switch opens at 2827-3050 kPa (410-440 psi) in order to interrupt the voltage to
the compressor clutch coil. Opening the switch stops the compressor from cycling. The switch prevents the pressure relief valve from discharging
refrigerant and oil.
