Refrigerant Pressure Sensor / Switch: Description and Operation
Compressor High Side Cut-Off Switch
This system is equipped with a high pressure cutoff switch. This switch is normally closed, and opens at 2827-3103 kPa (410-450 psi) to interrupt the
voltage to the compressor clutch coil. This will stop the compressor from cycling and prevent the pressure relief valve from discharging refrigerant and
oil.
