Abstract: A plastic ignition high voltage switch housing comprising two separately molded components formed of a high temperature, high strength insulating thermoplastic material, each component containing one bushing. The two components are spun welded together while maintaining axial alignment of the bushings. The two components can be designed to permit the placement of a gasket between them prior to spin welding, thereby capturing the gasket within the housing.

Abstract: A shaft coupler for connecting a distributor shaft of an ignition distributor to the camshaft of an internal combustion engine. The coupler comprises a plastic member having a pair of drive lugs located in a groove formed in the end of the camshaft. The plastic member has another pair of lugs located in a groove formed in a driven metallic member that is connected to the distributor shaft. Rubber sleeves are disposed about these lugs and torque is transmitted from the plastic member to the metallic member through the sleeves. The two members are secured together by arms that extend from the plastic member through slots formed in the metallic member. The arms have teeth engaging a face of the metallic member.
