<p>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.</p> |
