ABSTRACT:
A multi-slider electrical assembly comprises a metal case having a channel-shaped cross-section mounted on a substrate. The case has parallel slits, and guide blocks are spaced apart in parallel within the case for guiding a plurality of sliders extending through the slits. The case has an engage projection and semi-projections on each side thereof formed at each corner on its side walls. The engage projections are bent in contact with metal layers on the bottom surface of the substrate, and the semi-projections bear on grounding layers on the upper surface of the substrate, in order to hold the substrate therebetween without crushing it and to provide a good ground for the case.
