Dead-front user interface

摘要

A capacitive touch switch is disclosed which includes a transparent insulating panel, a filtering layer having an opaque color, a transparent icon being defined in the filtering layer, a transparent substrate including a capacitive electrode, the transparent substrate being tinted to substantially match the opaque color of the filtering layer, and a light source configured to transmit light through the transparent substrate, the transparent icon, and the transparent insulating panel when energized. A user interface and a method of manufacturing a capacitive touch switch are also disclosed.
