Abstract
A touch switch includes a touch input section, a metal piece provided to the touch input section at a surface thereof, and at least two induction-type proximity sensors so provided as to face the metal piece. The induction-type proximity sensors are arranged in parallel to each other and each have an LC oscillation circuit that output signals that changes in accordance with the distance to the metal piece. A duplicated touch switch that requires no stroke and achieves switch duplication is thus provided.
