Pressure flaps serve to protect the air-conditioning system against damages due to excessive or too little pressure levels. Distinctions are made between low-pressure switches, high-pressure switches and trinary switches. The trinary switch contains the high- and low-pressure switches, as well as an additional switch contact for the condensing and coolant cooler

Electrically powered actuators for air-conditioning systems ensure the proper distribution of the air flow inside the vehicle interior. They mainly come with automatic air-conditioning systems for controlling the air and/or blending flaps, thus directing the air flow to the desired direction. A defective control (actuator) can pose a safety risk if a steamed-up or iced window impacts visibility or if an unpleasant room temperature or draft air impact the driver directly.
