ABSTRACT:
A trigger operated speed control wherein the insulating housing is a two-shot molding having metal conductors plated on one of the molding materials on various external and interior surfaces. Stationary contact elements are secured to respective plated conductors within a housing cavity, as are terminals of the FET on an external surface of the housing. A printed circuit board is secured to the housing over an open side thereof to close the housing cavity, retaining all movable parts of the control within the cavity, the board having plated through holes which receive and are soldered to plated pin projections of the housing to secure the board to the housing and complete selected conducting paths between plated conductors and printed circuit traces. A plated molded pin projection also receives a pin receptacle terminal of a separate reversing switch unit when positioned in a pocket formed in the housing.
