Abstract
An electromagnetic actuator for operating a setting member includes an electromagnet which has a housing provided with a recess having an opening; a yoke body having a surface constituting a pole face of the electromagnet; and a solenoid surrounding the yoke body. The yoke body and the solenoid are accommodated in the housing recess. An armature, to which the setting member is coupled, is guided for motions towards and away from the pole face in a space adjoining the electromagnet. The opening of the housing recess faces the space. A resetting spring exerts a force opposing a motion of the armature towards the pole face.
