AC compressor trinary low high pressure switch with wire
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.

Auto Air Conditioning Refrigeration Pressure Switch
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.

Pressure Switch For Refrigeration System
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 and seal it at the same time.

Automobile Air Conditioning Pressure Switch
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 pressure switch. The pressure switch is generally connected to the compressor, the condenser electric fan or the water tank fan. It is controlled by the ECU on the car and controls the opening of the fan according to the pressure change in the air conditioner. Turn off, or the air volume, when the pressure is too high, the compressor will stop working to protect the system.

12v /24v Barb Fitting normally open or normally closed pressure switch
This is a pressure switch with a pagoda-shaped joint, and its joint is in a continuous cone shape.
So it can be better connected with water pipes and air pipes.
This pressure switch is mostly used in air compressors, small air pumps, and water pumps, air tank.
Air pipe or water pipe can be installed at its interface.

High And Low Pressure Pressure Switch
This pressure switch can be used in many fields, such as air conditioning refrigeration systems, car horns, ARB air pumps, air compressors, etc.In the refrigeration and air-conditioning system, the general air-conditioning pressure switch is installed in the air-conditioning condensing pipe, mainly to detect the pressure of the refrigerant in the air-conditioning pipe.When the pressure is abnormal, the corresponding protection circuit is activated to prevent damage to the system.Common air-conditioning pressure switches generally include high-pressure switches, low-pressure switches, two state pressure switches and three state pressure switches.

Water Flow Sensor And Water Flow Switch
Water flow sensor refers to the water flow sensing instrument that outputs pulse signal or current, voltage and other signals through the induction of water flow. The output of this signal is in a certain linear proportion to the water flow, with corresponding conversion formula and comparison curve.
Therefore, it can be used for water control management and flow calculation. It can be used as a water flow switch and a flowmeter for flow accumulation calculation. Water flow sensor is mainly used with control chip, single chip microcomputer and even PLC.
