Abstract

An electromagnetic actuator includes an electromagnet; and an armature movable toward the electromagnet by an electromagnetic force generated upon energization of the electromagnet. The armature is connectable to a setting member displaced as a function of armature motions. The electromagnetic actuator further has a resetting spring which opposes the electromagnetic force and which has a first end supported in a housing and a second end; and at least one jointed connecting arrangement interposed between the resetting spring and the armature for supporting the armature on the second end of the resetting spring.
