Abstract
The invention relates to a cap () for a display and/or control element. Said cap () comprises a cap member () for covering a light source () and optionally also actuating a switch of an associated control element. A luminous area or projection area is embodied in the cap member () in such a way that a symbol represented on or through the luminous area or projection area becomes visible on an operator's side of the display and/or control element by irradiating the symbol by means of a light source (). The luminous area or projection area encompasses a light-permeable metal coating () which is preferably applied using a PVD process. The cap is characterized in that the metal coating () has a three-dimensional contour () for representing the symbol. The invention further relates to an associated production method, a display or control element comprising said cap, and a use.
