ABSTRACT:
A remote touch-pad control panel for a domestic appliance coordinated with a sound system for selecting domestic appliance functions whereby a different sound is audible for each function pad touched by the operator. The touch control panel has an imporforate flexible plastic skin coextensive therewith having indicia pads with the skin superimposed on a rigid outer insulating sheet having a plurality of spaced apart apertures arranged in a preselected pattern therein. The flexible skin pads have contacts on their inner surface paired with fixed contacts on an inner rigid sheet spaced by an intermediate frame from the outer sheet whereby a deflecting touch control force through the flexible plastic skin pad establishes electrical connection between the paired contacts to operate the appliance function selected and energize the sound associated therewith.
