Working Principle:
This series products 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. When the pressure is reduced to below the recovery point, the pressure control can be reset automatically.

Application:
This series products are a super load pressure switch, the maximum pressure set point is up to 750psi, the maximum rated current is 25A, the switch has normally open and normally closed configuration. It is widely used in refrigeration units, all kinds of air conditioner, air compressor, oil pump and other industrial equipments which need to regulate the medium pressure to protect the system.
