ABSTRACT:
A circuit board structure is provided with a compact switching system for selectively connecting and disconnecting a pair of electrically conductive lead portions thereof. The switching system includes a through hole formed in the substrate portion and extending between its opposite sides. The interior side surface of the through hole is plated with an electrically conductive metal material. Portions of the plating are then removed to leave a mutually spaced plurality of plating segments within the through hole. Each plating segment is connected to an end of one of the circuit board leads. A switch structure is provided and has a contact portion which is insertable into the through hole and movable therein, into and out of engagement with a pair of the spaced plating segments, to selectively and electrically couple the circuit board leads associated with the plating segment pair.
