ABSTRACT:
A composite part and a method of manufacturing the same, comprising a plurality of pairs of terminal members formed in punched regions of a lead frame opposite to each other and shaped by cutting at predetermined positions a plurality of pairs of projection segments coupled at the respective base portions thereof; a plurality of circuit parts disposed and connected between the pairs of projection segments, and an armor molded in a region except the circuit parts and the base portions of the projection segments. The fore ends of the projection segments extending outward from the armor and formable into different shapes depending on the cut points are bent along the wall surfaces of the armor. Accordingly, there can be produced a composite part having any desired one of various functions by selectively changing the cut points of the projection segments. Since such selective change of the cut points can be achieved in the stage of use as well as that of manufacture, a remarkable advantage is attainable.
