Patent ID: 7768368

Claim:
Electromagnetic actuating apparatus with an armature unit, which is guided axially in a housing ( 10 , 22 , 11 ) and is capable of being moved by means of energizing a coil apparatus held on a spool, contact plug means ( 14 , 16 ), which are held in an insulator unit ( 12 ), being associated with the coil apparatus, and an elongated ground contact ( 16 ) of the contact plug means being electrically conductively connected to the housing, characterized in that the housing comprises: a housing body ( 10 ); a yoke section ( 22 ) at a front end of the housing body; and a guide tube ( 11 ) carried by the housing body and having a central passageway accommodating an armature assembly ( 13 ); and the ground contact interacts electrically conductively at an engagement end which is opposite its free end with said yoke section in such a way that, in a fitted state, a cutout formed in the engagement end in the ground contact engages over a projection ( 20 ) of the yoke section and/or at least partially surrounds it.
