| 摘要 |
The invention relates to a bistable electromagnetic actuator device comprising a permanent magnet means (12; 12a, 12b) and an armature unit (18) having a plunger unit (10) which extends in a direction of movement and can be moved by stationary electromagnetic drive means (22) to at least one of two end and/or stop positions that are stable in a de-energized state. A housing (20) which at least partially surrounds the armature unit is provided with stationary magnetic field detection means (34; 34a, 34b) for contactless interaction with the permanent magnet means in at least one of the end or stop positions which is provided for the purpose of detecting the armature position. The end face of the plunger unit has an engagement portion (28) for interacting with an actuating partner in a contacting and formfitting manner, such that when the electromagnetic drive means are deactivated, more particularly de-energized, formfitting contact and/or actuation by the actuating partner causes the armature unit to move to one of the end or stop positions in which the armature unit remains stable in a de-energized state, and the magnetic field detection means are arranged and connected so as to generate and output a detector signal which corresponds to said end or stop position, more particularly after the contact or actuation. |
