The method for producing operating keys, ornamental covers etc. with finely-structured symbols involves engraving of the rear side of a carrier plate, and coating of this side with a material layer and a foil. It further involves material removal from the front side of the carrier plate until the engraving is fully or partially laid bare, and covering of this side of the carrier plate with a protective layer. An independent claim is also included for an operating key produced by the proposed method. |
