A/C Low Refrigerant Pressure Switch
DESCRIPTIONThe A/C Low Refrigerant pressure switch is located in the low pressure refrigerant line.
OPERATION
When pressurized, the switch is closed and allows the compressor clutch relay to energize, feeding battery voltage to the compressor clutch coil. If the pressure drops below 2 psi, the switch opens and cuts off voltage to the clutch.
