Load switch closing operation:
operating handle insert closing operation shaft hole (bottom right) clockwise rotation 180°, Institutions drive the contact rapidly do closing operation load switch.
Load switch break-brake operation:
operating handle counterclockwise rotation180 ° to complete the operation.
Load switch earthing operation:
operating handle insert ground operation shaft hole (top right) clockwise rotation 180 °, do the grounding switch institutions drive the contact rapidly. Break-brake operations of earthing switch Just insert the operating handle grounding operation shaft, counterclockwise rotation 180 °. Complete the operation.
