Handle of industrial cut-off switch with improved safety using multiple locks

A handle of an industrial cut-off switch using multiple locks to improve safety, which is installed to actuate the industrial cut-off switch, the handle comprising:

• a fixing unit formed on an outer surface of an enclosure of the industrial cut-off switch;
• and
• a rotation unit which is formed to be rotatable while covering one side of the fixing unit, is connected to a shaft unit extending from a switch unit inside the enclosure, and rotates the shaft unit together as the rotation unit turns, thereby changing an on/off state of the switch unit,
• wherein the handle is provided with a plurality of locking means, and the rotation unit is able to rotate in one direction to a limit of its rotational operating range to change the switch unit to the on state when all of the provided locking means are unlocked,
• wherein the rotation unit is configured to be able to gradually rotate by a predetermined range by an external force whenever each locking means is unlocked, so that a degree of unlocking of the handle is able to be visually checked.
• wherein the fixing unit comprises an inner locking ring in which a plurality of first locking holes are horizontally arranged to correspond to a curvature,
• the rotation unit comprises an outer locking ring which is formed to cover the inner locking ring and in which second locking hole are horizontally arranged to correspond to the first locking holes, and
• a pair of the first locking hole and the second locking hole corresponding to each other serve as one locking means and provide a locking function by using a locking device which is fastened in a state of passing through the pair of the first locking hole and the second locking hole.
