The actuator or driver allows a wide tolerances at the inputs while still precisely selecting the image positions. The module includes a light absorbing shield disposed about a light source and having a light opening positioned and sized to provide illumination of the icon, containment of light not directed through the light opening, and control of the angle of light emitted from the opening.
