Rotating electronic part and method of manufacturing the same

摘要: A rotating electronic part has a board; case composed of insulating resin; supporting projection made resin integrally structured with the case; and member. The board is provided central hole three or more notches around at even angular intervals. fixes so as to maintain penetration state on board. Each projections partially in one projects an inner radius hole. member shaft inserted rotatably supported distal ends projections; contact that faces board, makes rotational movement rotation shaft, contacts output electric signals outward.
