Abstract

An electromagnetic control mechanism (1) with an actuating element (15) which can move longitudinally and can be retained in three stable positions. By way of two coils (3, 4), the actuating element (15) can be switched to a first or to a second stable position, namely, the two opposed end positions. The actuating element (15) comprises an actuator rod (7) with a permanent magnet (8) arranged on the actuator rod (7), such that the actuating element (15) can be retained magnetically in the third stable position by the permanent magnet (8).
