The automobile air-conditioning pressure switch detects the pressure of the air-conditioning pipeline, and then transmits the pressure signal to the air-conditioning control system to protect the air-conditioning compressor and the pipeline! The air conditioner can work normally only when the pressure signal is within the normal range!Air-conditioning pressure switches usually have three wires, one is 12v. The other two are a high-pressure switch and a normal pressure switch.When the pressure is too high, the electromagnetic clutch of the compressor will be disconnected. When the pressure on the high-pressure side is higher than a certain value, the high-pressure switch will be opened to allow the fan to rotate at a high speed, without damaging the system due to high pressure.The compressor will not work when the pressure is lower than a certain value, so that the compressor will not be damaged.
