Best Price for China yk Series Automotive Air Conditioning Pressure Sensor with CE
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 pressure is high, force the condensing fan to rotate at a high speed to reduce the high pressure pressure and increase the cooling effect.
High pressure switch: In order to prevent the system pressure from being too high, causing the system to explode, the compressor is forced to stop working. When the high-pressure pressure of the air conditioner is abnormally high, the high-pressure switch is opened to cut off the control circuit of the compressor, and the air-conditioning system stops working.

Leading Manufacturer for China Air Ride Suspension Train Horns Bagged Air Compressors pressure switch
The mechanical pressure switch is a micro switch action caused by pure mechanical deformation.When the pressure increases, the different sensing pressure components (diaphragm, bellows, piston) will deform and move upward. The upper micro switch is activated by a mechanical structure such as a railing spring to output an electrical signal. This is the principle of the pressure switch.

Wholesale Discount China High Pressure Series Pressure Switch for Conditioner and Other Refrigeration System
The pressure switch is installed on the high-pressure side of the air-conditioning system.When the refrigerant pressure is ≤0.196MPa, since the elastic force of the diaphragm, the butterfly spring and the upper spring is greater than the pressure of the refrigerant, the high and low pressure contacts are disconnected (OFF), the compressor stops, and low pressure protection is realized.
When the refrigerant pressure reaches 0.2MPa or more, this pressure is higher than the spring pressure of the switch, the spring will bend, the high and low pressure contacts are turned on (ON), and the compressor operates normally.

Original China High-Power Portable Industrial Airbrush Oil Free Piston Air Compressor Pump Pressure Switch
The working principle of the pressure switch is that if the pressure in the pressure switch system is higher or lower than the initial set safety pressure value, the internal disc of the pressure switch can detect and issue an alarm in time, and movement occurs, and the connection of the pressure switch is connected to the power supply , So that the connection of the pressure switch turns on or off the power.The water pressure switch is usually set to a fixed value when in use. That is, when the actual value is less than the fixed value or greater than the fixed value, an alarm will occur and movement will occur to cause a connection with another link. Turn the power on or off. When the water pressure in the system reaches a fixed value, it returns to its original state.
