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
