YCHGLZ1-125~3200A Changeover Switch

Features

(DMC)for the switch housing,which has high dielectric performance,protection capa-bility,and reliable operating safety.The operating mechanism is a spring-stored energy,instantaneous release acceleration mechanism,with instant connection and disconnectiondual-breakpoint contact structure.It is independent of the speed of the operating handle,greatly improving the electrical and mechanical performance.

The side-operated isolation switch adds a side-operated mechanism on the basis of thecentral front-operated isolation switch,which is suitable for the connection and disconnec-tion circuit and electrical isolation on the side.

The double-throw isolation switch is composed of two isolation switches stacked up anddown or arranged side by side,which is suitable for the switching of dual power supply ortwo load devices,as well as for safety isolation.

The switch has a beautiful and novel appearance,simple structure,and easy operation.
