Patent ID: 7030723

Claim:
An electromagnetic switching device, comprising: an electromagnetic drive apparatus; a moving contact element, operatable by the drive apparatus and switchable between a bridging position, adapted to connect a pair of stationary contacts, and a disconnected position, adapted to disconnect the stationary contacts; an actuating apparatus including an actuating element adapted to interact with the moving contact element and moveable between an operating position and a safe position, wherein, in the operating position, the moving contact element is switchable by the electromagnetic drive apparatus between the bridging position and the disconnected position, and wherein, by movement of the actuating element to the safe position, the moving contact element is adapted to move from the bridging position to the disconnected position, and is adapted to be blocked in the disconnected position; wherein the moving contact element is adapted to be blocked in the bridging position by the actuating element when the actuating element is in an on position.
