China Supplier Normally Open Oil Pressure Switch - High And Low Pressure Pressure Switch – Anxin

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.

All ex-factory products have undergone rigorous leak testing and pressure testing,The warranty period of our products is one year or 100,000 times, whichever comes first,In order to meet the needs of the market, our company has developed products with a life of 500,000 to 1 million cycles, high-voltage resistant, and high-current products. Please contact us for details.

In the use of car air conditioner, when there are abnormal conditions such as blockage of the cooling fins, non-rotating cooling fans, or excessive refrigerant, the system pressure will be too high. If it is not controlled, the high pressure will damage the system components. This switch is mainly used in automobile air conditioning and refrigeration systems. It is installed in the pipeline between the dry receiver and the expansion valve as a safety control for the refrigeration system. Its characteristics are: automatic reset, working state can be normally open or normally closed, instantaneous action, sealed package, use the elastic element in the switch for reverse action, Guiding the drive to open or close the circuit. The switch automatically resets when the pressure drops to a predetermined value. Taking into account the specific pressure stability, durability, air tightness and other technical conditions of automobile air conditioners, our company selects German and Japanese raw materials for some parts. The available products are: signal state, two-states and three-states pressure switches, suitable for R12, R134a and other refrigeration media. And can be designed and manufactured according to user requirements.
