A metallic interrupter ultrasonically welded to a thermoplastic polyester sleeve or hub eliminates the need for a hardened steel washer by operating the hub directly on a predominantly iron-composite surface by providing a land formed with the hub. The hub has a bottom flange of circular shape with a shaft opening for communication with the distributor rotor and stakes for connection with the interrupter. A bored cylindrical portion is affixed concentrically to the bottom flange; and the land on the underside of the bottom flange communicates with the bowl shaped housing. |
