Patent abstract

A conductive tracing for a keyboard including a pair of electrically conductive paths that are electrically isolated from each other. The pair of electrically conductive paths may each include conductive surfaces that are electrically coupled together. Each of the plurality of conductive surfaces of the pair of electrically conductive paths extend radially between a center portion and a peripheral portion of the conductive tracing. One or more of the conductive surfaces may include a pair of outer edges that are substantially parallel to a respective radial direction that the outer edges extend in. The conductive surfaces of one of the pair of electrically conductive paths may be complementary formed to the conductive surfaces of another of the pair of electrically conductive paths. The conductive tracing may be substantially symmetric about an axis that passes through the center portion of the conductive tracing.
