Abstract

A touch sensor pad, including a touch sensor that senses the presence of a touching member placed proximate the touch sensor. A layer of protective material overlies the touch sensor. The layer of protective material has a first surface proximate the touch sensor and an opposing second surface distal from the touch sensor. The second surface includes a resting surface portion and a developed surface portion. The developed surface portion is recessed below the resting surface portion such that the developed surface portion is nearer to the touch sensor than the resting surface portion. The touch sensor has a sensitivity such that the presence of a touching member in contact with the resting surface portion does not result in an actuation of the touch sensor while the presence of a touching member pressed into the developed surface portion does result in the actuation of the touch sensor.
