The pressure switch is mainly used in the refrigeration system, in the pipeline circulation system of high pressure and low pressure, to protect the abnormal high pressure of the system to prevent damage to the compressor.
After being filled, the refrigerant flows into the aluminum shell (that is, inside the switch) through the small hole under the aluminum shell. The inner cavity uses a rectangular ring and a diaphragm to separate the refrigerant from the electrical part ...

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...
