Working Principle:
This series products are mainly uses the characteristics of the built-in stainless steel snap disc to be snapped under a certain pressure,when the disc snaps, it can drive the conversion of electrical contacts through a transfer pin,and the pressure is reduced to below the recovery point, it can be reset automatically.

Range of application:
This series products are mainly used in the air-conditioner (house used,commercial used and automotive),ice making machine, refrigeration equipment system and so on. It can also be used in all kinds of air vacuum pump, agricultural machinery for air and hydraulic pressure system.
