![]() ![]() ![]() The apparatus of claim 1, in which the metal plate has a first thickness and includes a plurality of blind holes extending into the metal plate at the opposing planar surface to provide a second thickness of the metal plate less than the first thickness in the plurality of defined areas.ģ. An apparatus, comprising: a metal plate having a plurality of defined areas forming touch sensors on an first planar surface, and having an opposing planar surface, the metal plate configured to be deformable in the plurality of defined areas by a human touch, and the metal plate having non-touch areas in areas other than the defined areas and a circuit board having 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.Ģ. ![]()
