The invention relates to a cap (1) for a display and/or control element, comprising a cap member (2) for covering a light source and/or actuating a switch of an associated control element. A luminous area or projection area is embodied in the cap member (2) in such a way that a symbol (5) represented on or through the luminous area or projection area becomes visible for an operator of the control element by irradiating the symbol (5) by means of a light source located on the switch side. The cap (1) is characterized in that the luminous area or projection area encompasses a light-permeable metal coating (4) which is preferably applied using a PVD process. The invention further relates to an associated production method, a display or control element comprising said cap, and a use.
