Generally, pressure switches are installed in automobile air-conditioning refrigeration systems.Pressure protection switches include high pressure pressure switch, low pressure pressure switch, high and low pressure combination switch a...
The automobile air conditioner pressure switch is a part to protect the air conditioner refrigeration, it can adjust the pressure in time.When the refrigerant pressure in the air conditioning system is too high or too low, the pressure switch is turned off, so that the compressor does not work (the pressure switch and other switches control the relay to control the compressor) and protect the system components from damage.Generally divided into two-state pressure switch and three-state pressu...
