Function The Car Air Conditioner Switch Sensor prevents the refrigeration system from operating under extreme refrigerant pipeline pressure and helps control the speed of the engine cooling fan. Material Made of ABS material. Not easy to wear or rust; strength; solid and practical. Performance Stable performance and reliability. Professionally manufactured with exquisite workmanship. Withstands harsh temperatures and conditions. Installation Simple to install. Directly old or damaged ones without modification. Convenient to use and saves time and effort. Key benefits Protects the A/C system from overpressure, reducing risk of damage. Maintains engine cooling fan operation for reliable cooling. Durable ABS construction for long life in demanding temperatures. Easy, nomodification replacement that fits as a straightforward upgrade or . Use scenarios Scenario 1: In hot or demand driving, the sensor helps prevent overpressure in the refrigerant line while regulating cooling fan speed. Scenario 2: Replacing a worn or faulty pressure switch to restore stable A/C performance and consistent engine cooling fan control. Scenario 3: Routine maintenance or where a direct, nomodification replacement improves reliability and reduces downtime.
