LP switch means Low pressure switch. This switch is installed on the suction side of the compressor on the copper pipe. LP switch senses the pressure in system and if due to any reason like leakage of refrigerant, low gas charge it will cut the system which is called tripping. These switches has a range of pressure according to the capacity of the refrigeration or air
