Abstract

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.
