Description
Working Principle
The series of pressure switches are made based on the theory that an inside reversible stainless steel motion diaphragm turns over when inducing a certain pressure .The electric contact(H)opens and electric contact(L)closes simultaneously when the diaphragm moves/When the system pressure reduces,the diaphragm resets instantly ,with the function of Switch Spring,The electric contact disconnects from contact(L)and connects with contact(H)automatically.
Application
The product is mainly used in regrigeration system of air-conditioner and precise pressure control system;It can also be used as the precise high-low pressure protection of variety of equipment and tools.
