摘要
A half wave and full wave energization system for permanent magnet D.C. motors employing a hand trigger operated switch which commutates terminals of a full wave rectifier bridge when connected to a source of A. C. supply to provide selectively half wave and full wave energization of such motors when the trigger is depressed from an extended "off" position.
