ABSTRACT:
A power source for a pair of solenoid coils selectively acting in opposite directions on a single armature. The source includes a selectively variable D.C. power source selectively energizing either coil with opposite magnetic polarity and a dither signal generator which continuously supplies out of phase dither signals to the two coils.
