ABSTRACT:
A magnetically actuated switching device using reversibly magnetizable armatures treated by a selective annealing process. The annealing process changes the homogeneous coercive magnetic properties of the armatures so that the highest coercive force is caused to occur in the region of the armature which is subjected to magnetizing forces from an energizing coil, and the region of the armature existing outside the magnetizing field is annealed in a manner to lower the coercive force of the armature. Selectively annealing the armature to provide high coercive force in the vicinity of the magnetizing coil reduces the amount of magnetizing force necessary to be supplied by the coil for switching the armature from a closed to an open contact position.
