ABSTRACT:
A safety lock device for a toggle switch has a cylindrical head with slotted opening in its perimeter, a threaded outer surface, flared skirt and an open base. Vice arms are attached within the device with its arms protruding through its slotted perimeter. The vice arms have opposed, grooved heads spaced within the open base. A lock ring with teeth on its inner surface and a plurality of screw holes through its upper surface, slides over the cylindrical head with the teeth in the slotted outer perimeter of the cylindrical head. The lock ring forces the grooved heads into a clamping position of the toggle switch. A flanged lock nut with a hole in its flange is threaded to mate with the cylindrical head and lock ring. The hole in the flange is aligned with one of the screw holes of the lock ring and a screw is inserted into the aligned holes to lock the device in locking position.
