Abstract
An improved cabinet for electromagnetic and radio-frequency interference suppression includes an electrical component-mounting rail that includes a series of spring-like conductive projections or tabs internally formed to extend from its surface. The projections are arranged so that, as a component panel is mounted against the rail, the projections contact the panel at a plurality of points, establishing electrical contact between it and the rail. The projections are positioned to maintain distances between radiation-suppressing low impedance contacts of the rail and component which are small in comparison to wavelength of interference generated by the component and, thereby, to attenuate emissions from the cabinet.
