Abstract
A bistable electromagnetic actuator device, a permanent magnet means (), as well as an armature unit () with an elongate plunger unit () extending along a moving direction, wherein said armature unit can be moved into at least one of two end and/or stop positions that are stable in the deenergized state by means of stationary electromagnetic driving means (), wherein stationary magnetic field detector means () are assigned to a housing (), which at least sectionally encloses the armature unit, for the contactless interaction with the permanent magnet means in at least one of the end or stop positions provided for the armature position detection, wherein the plunger unit features a terminal contact and/or engagement section () for interacting with an actuating partner in a contacting and non-positive fashion such that a non-positive contact and/or actuation by the actuating partner causes a motion of the armature unit into one of the end or stop positions, in which the armature unit remains in a stable fashion in the deenergized state, when the electromagnetic driving means are deactivated, and wherein the magnetic field detector means are arranged and wired for generating and outputting a detector signal corresponding to this end or stop position.
