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.
