Abstract
An improved selection panel having a plurality of touch-actuated capacitive switches thereon. Each capacitive switch in the panel includes a transparent glass substrate having transparent conductive coatings on opposite sides thereof to form a capacitor. A display support is positioned behind and adjacent to the plurality of capacitive switches, and provides a separate display card support for each capacitive switch. A removable display card is positioned in each separate support in a manner such that each of the display cards may be changed periodically.
