ABSTRACT:
A capacitor for magneto or ignition applications comprises an inwardly embossed X-configuration on the bottom of the shell for providing good electrical and mechanical contact with the adjacent exposed foil capacitor counterturns to in turn provide low series resistance and inductance and minimum rotational movement of the capacitor winding. At the other end of the shell, a terminal assembly is provided with an arcuate spring which electrically contacts the other exposed foil counterturns through the medium of a perforate contact washer. During assembly, the terminal assembly is forced toward the embossed bottom of the shell to preset the capacitor components by embedding the X-shaped embossment into the adjacent counterturns and to embed the opposite counterturns into the perforate contact washer. In this assembled configuration, electrical and mechanical contacts are ensured so that the effects of heat and vibration do not cause contact separation and arcing.
