A designator (700) adapted as an actuator for an elastomeric membrane keypad (1100) sandwiched between a circuit board (1203) and a housing (1201). The designator (700) has a substantially translucent substrate (701). A top surface of the substrate (703) has substantially translucent (705) and substantially opaque (707) portions for producing negative (800) or positive (1000) image graphics. Upper side surfaces of the substrate (709) adjoining the top surface (703) are substantially opaque. Lower side surfaces of the substrate (711) adjoining the upper side surfaces (709) are substantially translucent. A light source (1206) illuminates the graphics and the perimeter of the designator (1301). A preferred associated method describes constructing the designator using a two part insert molding process.

Désignateur (700) adapté comme actionneur pour clavier (1100) à membrane élastomérique placée entre une plaquette à circuit imprimé (1203) et un boîtier (1201). Le désignateur a un support (701) substantiellement translucide. Le dessus du support (703) a des parties substantiellement translucides (705) et des parties substantiellement opaques (707) pour produire des images négatives (800) ou positives (1000) Les surfaces latérales supérieures (709) près du dessus du support (703) sont substantiellement opaques. Les surfaces latérales inférieures du support (711) adjacentes aux surfaces latérales supérieures (709) sont substantiellement translucides. Une source lumineuse (1206) illumine les images et le périmètre du désignateur (1301). Une méthode associée préférée décrit la construction du désignateur suivant un procédé de moulage à élément rapporté en deux pièces.
