Abstract
An electromagnetic actuator for operating a setting member includes an electromagnet composed of a yoke body and a magnet coil held by the yoke body; an armature adapted to be coupled to the setting member; and a resetting spring for exerting a spring force to the armature. The spring force opposes the magnetic force generated by the electromagnet when energized. The armature is guided in a reciprocating motion which it executes in a direction of armature displacement in response to the magnetic and spring forces. The armature is provided with a plurality of throughgoing, slot-shaped apertures.
