ABSTRACT:
A rotary drive for a switch actuated by a toggle lever includes an operative connection which swivels, a first catch element on the operative connection, coupled to the toggle lever, and a second catch element on the operative connection. A mounting plate parallel to the switch base and a rotatable shaft are provided, the rotatable shaft disposed through the mounting plate. The rotary drive further includes a swivel arm on the shaft, a rotary knob coupled to the shaft configured to rotate the shaft. A mechanical connection couples the swivel arm to the second catch element, converting movement of the shaft into a movement of the operative connection. A swivel movement of the toggle lever is transferred to the second catch element, and the swivel arm enables the operative connection to swivel through a rotation of the shaft to move the toggle lever.
