Electromagnetic drive unit and an electromechanical switching device
Abstract:
An electromechanical switching device, especially a contactor or a multifunctional device including a contactor, includes at least one stationary contact piece, at least one movable contact piece movable to and from the at least one stationary contact piece for opening or closing a current path and an electromagnetic drive unit including a yoke and a coil and a movable armature. In at least one embodiment, the electromagnetic drive unit is adapted to displace the movable contact piece in response to a voltage applied to the coil. The at least one movable contact piece and the at least one stationary contact piece are adapted to limit movement of the armature after activation of the electromagnetic drive unit.
