<p>An input device includes an array of adjacent capacitive sensors arranged into rows and columns. Each capacitive sensor exhibits a capacitance characteristic when in proximity to a conductive element. A plurality of mechanical hysteresis mechanisms are each deposited on and in contact with each of the capacitive sensors and configured to be actuated by a corresponding push button. Each capacitive sensor exhibits an electrical characteristic upon actuation of the corresponding mechanical hysteresis mechanism. An insulating overlay layer positioned over the array of capacitive sensors and the plurality of mechanical hysteresis mechanisms defines each push button and defines a surface for accommodating the conductive element.</p>
