An actuating mechanism for an electrical switching device includes a frame and a driving member. The driving member is rotatably arranged in the frame around an axis and is movable between a first driver position and a second driver position. The driving member is mechanically linkable to the electrical switching device by a first linking member. The movable contacts of the electrical switching device are in a first position in the first driver position of the driving member and are in a second position in the second driver position of the driving member. The actuating mechanism further includes an actuating member. The actuating member is rotatably arranged in the frame around an axis and is movable between a first actuator position and a second actuator position by hand or based on using a motor. The actuating mechanism further includes a load spring.

An electrical system includes an enclosure for housing an electrical device. The enclosure includes a door with an operating handle connected to a first shaft that turns the electrical device on or off when the door is closed. The operating handle is further operable to simultaneously rotate a cam assembly, which in turn rotates a second shaft which displaces an interlock mechanism for engagement or disengagement to a busway structure.
