ABSTRACT:
An electromagnetic actuating device comprises a solenoid coil to which a control current can be applied and an armature associated with the solenoid coil which is adapted to carry out movements which are dependent upon a control current flowing through the solenoid coil and a spring arrangement for biassing the armature into opposite directions, with a holding position being defined which is assumed by the armature at a holding current through the solenoid coil, with the holding current flowing through the solenoid coil being variable to a higher value or to a lower value with the armature not leaving the holding position, and both the higher and the lower current value being able to be dimensioned in such a manner that interference influences on the magnetic and spring forces which actuate the armature do not bring the armature from its holding position into an actuated position which is different from the holding position.
