ABSTRACT:
An electromagnetic device adapted to operate with a battery of small capacity and having an armature arranged to move upon energization and de-energization of a coil, to and away from a yoke respectively. In order to insure that, after having been attracted, the armature is in intimate contact with the yoke over the entire prescribed area of interface therebetween, there is provided an annular elastic spacer which may be of round cross-section secured in an annular recess around a pivot pin for the armature at the center of length thereof and fitted in a vertical hole of the armature to permit not only absorption of the shock on the armature, thus protecting the attraction face, but also tilting movement of the armature about the spacer ring with respect to the yoke.
