Abstract: An auxiliary operating device for an electromechanical switching device having an operating mechanism. The auxiliary operating device including an actuating element couplable to the operating mechanism and movable between a first position and a second position, an actuation member movable relative to the actuating element between a third position and a fourth position, and a drive dog arrangement configured to cooperate with the actuating element and the actuation member. The auxiliary operating device further includes a coupling device movable between a release position and an operating position. The coupling device is configured, when in the operating position, so as to move the actuating element with the actuation member in a second direction of movement when the actuation member is in the third position. The coupling device is configured, when in the release position, so as to allow movement of the actuation member in the first and second directions between the third and fourth positions.

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.

Abstract: An electromagnetic switching device (2) with restricted guidance, in which the closure contacts do not come into contact when the break contact is welded or fixed. An elastically resilient transmission lever (10) is provided to establish the effective connection between the armature (8) and the contact support (12) extending at a distance from and parallel to the armature.
