发明名称 Electrical cover plate
摘要 A cover plate (100, 200) for accommodating a wide variety of different electrical outlets, switches and connectors is formed from a first layer of transparent material (120) that is laminated to a second layer of colored material (122) that is laminated to a third layer of metal (124). Prior to lamination of the third layer to the second layer, selected portions of the second layer are removed by machining or engraving. The engraved portion may be filled with paints that contrast in color to the color of the colored foil, providing selected areas with decorative and or informative information. The engraved portion is protected from wear and tear by encapsulation between the second layer (122) and the third layer (124).
