◉ This kind of load isolation switch is widely used in the distribution system and automatic system of architecture, power supply,petrochemical, and other industries.It has flexible structure of modularized design, and flexible combination.

◉ The shell made by unsaturated polyester resin reinforced by glassfibre. The on and off state of contact is observed through windows. 

◉ The operating mechanism is an elatic-accumulating accelerating mechanism for instant release, which makes instant on and off of the double breakpoint contact, It has no relationship with the speed of operating handle and increases greatly various electric properties and mechnical properties,

There are operations inside and outside the board. There are frontal and lateral operations. There are connections behind the board.
