Abstract: This invention is for a trigger switch apparatus for a hand held electric drill and includes a control of the electric power to a drill for fast or slow rotation of the drill bit by moving a rheostat contact bridge over a rheostat coil section for control of the rotation speed of the drill bit, and further a leaf spring holds the trigger carriage stop shoulder onto the carriage, and on seizure, kick back or sudden torque of the drill bit there is a cut off of power and the switch reverts to an “off” or “open” position, which then requires re-setting of the switch to a “closed” or “on” position for re-actuating operation of the hand held electric drill.
