Electric switching device with improved actuation mechanism

An Electric switching device, comprising:

• a switching contact,
• an actuation mechanism coupled to the switching contact and
• a motor coupled to the actuation mechanism,
• characterized in that
• the actuation mechanism comprises
• a first spring,
• a first actuation plate connected to or contacting the first spring and coupled with the switching contact,
• a second actuation plate connected to or contacting the first spring and coupled with the motor, wherein the second actuation plate is spaced from the first actuation plate with at least a part of the first spring in-between, and
• a first blocking element, which comprises a rotatable first flattened shaft and a first lever connected to the first flattened shaft and which is designed to block the first actuation plate in a rotational blocking position and to release the first actuation plate in a rotational release position,
• wherein the second actuation plate is movable in a first direction by the motor,
• wherein the first spring or said part thereof upon movement of the second actuation plate in the first direction is loaded,
• wherein the second actuation plate or an actuating element connected thereto upon further movement of the second actuation plate in the first direction contacts the first lever,
• wherein the second actuation plate or the actuating element upon further movement of the second actuation plate in the first direction turns the rotatable first flattened shaft from its rotational blocking position in its rotational release position and
• wherein the first flattened shaft upon reaching its release position releases the first actuation plate, which in turn is moved in the first direction by a release of the loaded first spring or said loaded part of the first spring and as a consequence transfers the switching contact into a first switching state.
