Abstract

Un designatore (700) adatto ad operare come attuatore per una tastiera a membrana elastomera (1100) inserita a sandwich fra un pannello di circuito (1203) ed un alloggiamento (1201). L'elemento designatore (700) presenta un substrato (701) sostanzialmente translucido. Una superficie di sommità (703) del substrato presenta una porzione sostanzialmente translucida (705) ed una porzione sostanzialmente opaca (707) per produrre una grafica ad immagine negativa (800) o positiva (1000). Le superfici laterali superiori (709) del substrato che si raccordano alla superficie di sommità (703) sono sostanzialmente opache. Le superfici laterali inferiori (711) del substrato che si raccordano alle superfici laterali superiori (709) sono sostanzialmente translucide. Una sorgente di luce (1206) illumina la grafica ed il perimetro dell'elemento designatore (1301). Un preferito associato procedimento descrive la costruzione dell'elemento designatore utilizzando un procedimento di stampaggio ad inserto in due parti.
