ABSTRACT:
A portable electric drill has a printed circuit board assembly mounted in a motor compartment and attached to a stator lamination stack. A motor reversing switch is mounted on the printed circuit board assembly and has an operating pin which cooperates with an actuating lever that is mechanically interrelated to a trigger switch for energizing the drill. The trigger switch remains inoperative until the actuating lever is positioned to allow the motor to be energized to drivingly rotate in either one or other rotational direction. The printed circuit board assembly also has mounted thereon brush holders, noise-suppression elements, brush terminals, and field coil terminals. A pivoted lever for operating the reversing switch pin may be disposed inside or outside the motor compartment.
