This is an air conditioner three-state pressure switch, which includes a high and low pressure switch and a medium voltage switch. The three-state pressure switch is installed on the high-pressure pipeline of the air-conditioning system.
Low-pressure switch: When the air-conditioning system leaks or the refrigerant is low, in order to protect the compressor from damage, the control circuit of the compressor is forcibly cut off to stop the compressor.
Mid-state switch: When the condensing pres...

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...
