The HVAC Pressure Switch manufacturer tells you that we have introduced the composition and working principle of each system of the car air conditioner before, and know the various states of the refrigerant in the air conditioner pipeline. The refrigerant is transformed into a low-temperature and low-pressure gas, and then becomes a high-temperature and high-pressure gas through the air conditioner compressor. The HVAC Pressure Switch manufacturer tells you that this kind of pressure monitoring is currently identified through the air conditioner pressure switch. But what is an air conditioner pressure switch?

The HVAC Pressure Switch manufacturer tells you that the air-conditioning pressure switch is installed in the air-conditioning condensing pipeline, mainly to detect the pressure of the refrigerant in the air-conditioning pipeline. The air conditioner pressure switch is sometimes called a two-state pressure switch, or a three-state pressure switch.
Bi-state pressure means that it can sense high and low pressures, while a tri-state pressure switch is also capable of sensing medium pressures. HVAC Pressure Switch manufacturers tell you that there are basically three-state switches on the market. The high-voltage switch and low-voltage switch are generally connected in series in the circuit, which is a normally closed switch, and the medium-voltage switch and high-voltage switch are connected in parallel, which is a normally open switch.
