AC pressure switch

The AC pressure switch is an important sensor in a vehicle's air conditioning system, monitoring the refrigerant pressure in the air conditioning circuit. It ensures that the air conditioning system operates only under safe conditions and protects vital components such as the air conditioning compressor from damage.

The pressure switch measures the pressure in the high- or low-pressure section of the air conditioning system and sends corresponding signals to the vehicle's control unit. If the pressure is too high or too low, the pressure switch can interrupt the operation of the air conditioning compressor or activate certain protective functions.

Excessive pressure can be caused by overheating of the system or a blockage in the refrigerant circuit. Excessive pressure can indicate a leak in the system or an insufficient amount of refrigerant. The pressure switch helps to detect such situations early and prevent damage to the air conditioning system.

The components consist of precision sensor elements, electrical contacts, and robust housings designed for use in the engine compartment. They must withstand temperature fluctuations, vibrations, and contact with refrigerants over the long term.
