Low Pressure Sensor / Switch: Description and Operation
Air Conditioning (A/C) Low Pressure Switch
The A/C low pressure switch is used for additional A/C system pressure control. This normally closed switch opens when the refrigerant pressure drops
below 152 kPa (22 psi). This results in the A/C turning off, preventing the evaporator from freezing.
