Actuating mechanism for an electrical switching device, comprising - a frame, - a driving member which is rotatably arranged in the frame around an axis and which is movable between a first driver position and a second driver position, wherein the driving member is prepared to get mechanically linked to the electrical switching device by a first linking member wherein movable contacts of the electrical switching device are in a first position in the first driver position of the driving member and are in a second position in the second driver position of the driving member, - an actuating member which is rotatably arranged in the frame around an axis and which is movable between a first actuator position and a second actuator position by hand or by means of a motor, - a load spring, which at its first end is mounted to a first mounting point on the driving member and mounted to a second mounting point on the actuating member, wherein the first mounting point is spaced apart from the axis of the driving member and wherein the second mounting point is spaced apart from the axis of the actuating member, - a first locking member and a second locking member which are mounted to the frame each being movable between a locking position and a release position, - wherein in a first final state the driving member is in its first driver position and the actuating member is its first actuator position and locked by the first locking member, which is in its locking position, - wherein in a second final state the driving member is in its second driver position and the actuating member is its second actuator position and locked by the second locking member, which is in its locking position, - wherein during a transition from the first final state to the second final state - the load spring is loaded upon a movement of the actuating member towards its second position, wherein the driving member is held in its first position by the first locking member and wherein the first locking member is moved into its release position by the actuating member before or when the actuating member reaches its second position, - wherein the driving member, caused by the force generated by the load spring, moves into its second position when the first locking member moves into its release position and - wherein the second locking member is moved into its locking position before or when the driving member reaches its second position, characterized in that - the axis of the driving member coincides with the actuator axis of the actuating member. - a frame, - a driving member which is rotatably arranged in the frame around an axis and which is movable between a first driver position and a second driver position, wherein the driving member is prepared to get mechanically linked to the electrical switching device by a first linking member wherein movable contacts of the electrical switching device are in a first position in the first driver position of the driving member and are in a second position in the second driver position of the driving member, -
