Abstract: In described examples, an apparatus includes a metal plate having a plurality of defined areas forming touch sensors on a first planar surface, and having an opposing planar surface. The metal plate is arranged to be deformable in the plurality of defined areas by a human touch. A circuit board has a plurality of conductive sensors on a first surface arranged with the plurality of conductive sensors facing and spaced from the opposing planar surface of the metal plate, the conductive sensors placed in correspondence with the defined areas on the metal plate so that deflection sensors are formed in the defined areas by the conductive sensors and the opposing planar surface of the metal plate. Methods are described.
