Abstract: A conducting contact pair for a switch has a first conducting contact formed by a plurality of outward extending radial fingers arranged on a substrate, and a second conducting contact formed by a plurality of inward extending radial fingers. The first conducting contact and the second conducting contact are arranged with each inward extending radial finger extending between a corresponding pair of adjacent outward extending radial fingers. A bridge conductor is selectively pressed against the first conducting contact and the second contact to bridge any of the inward extending fingers to either of pair of adjacent outward extending radial fingers that it extends between.
