Backlighting appliance deadfronted user interfaces

A method of manufacturing a capacitive touch switch, the method comprising:

• defining a transparent icon in a filtering layer;
• positioning the filtering layer on an insulating panel;
• aligning the insulating panel with a transparent substrate including a capacitive electrode;
• positioning a printed circuit board between the filtering layer and the transparent substrate, the transparent substrate including a void;
• positioning the transparent substrate at least partially within the void adjacent to the filtering layer such that the filtering layer is positioned behind the insulating panel and the transparent substrate is positioned behind the filtering layer;
• positioning a light guide adjacent to the transparent substrate;
• and
• securing an opaque cover adjacent to the light guide, the opaque cover colored to substantially match an opaque color of the filtering layer.

A user interface, comprising:

• a filtering layer positioned behind an insulating panel, the filtering layer having an opaque color and defining a plurality of transparent icons;
• a printed circuit board positioned behind the filtering layer and including a void and a circuit board terminal block that extends partially into the void;
• a transparent substrate including a plurality of capacitive electrodes, the transparent substrate being formed of a tinted material, the transparent substrate being aligned with the void and including an electrode terminal block configured to interface with the circuit board terminal block;
• and
• a plurality of light-emitting diodes operably coupled with the printed circuit board, each of the light-emitting diodes configured to transmit light through a portion of the transparent substrate, at least one of the plurality of transparent icons, and a portion of the insulating panel when energized.
