ABSTRACT:
An improved magneto system of the type employing a U-shaped tiltable armature within an electromagnetic relay wherein the armature is capable of tilting to provide an operable airgap between the armature and the yoke in order to increase the magnet force against the contacts when one of the contacts becomes stuck. The improvement provided a three-point support to the armature by resting each of the armature arms on its corresponding contact spring bank and resting a portion of the center region of the armature on the yoke.
