Abstract
A switching assembly includes an insulative substrate upon which is carried a plurality of conductive paths respective portions of which are selectively bridged upon depression of a resilient conductive contact element. That contact element is generally in the shape of a dome and has a central region of substantially planar conformation from which the remainder of the dome slants integrally downward and outward to a lower marginal rim portion. The dome-shaped element is disposed adjacent to the substrate with at least a portion of its rim portion electrically and physically contacting one of the portions of one of the paths. The central region is generally in registry over another of the portions in another of the paths so as to enable connection between the central region and that other portion upon depression of the central region.
