The invention relates to a visible or input part (2) forming a visible or input surface (3) that is translucent or transparent at least in some regions; a support (12) for securing the operating or display element to an external structure, in particular a motor vehicle component; an optional detection device (13, 18, 19) which is designed to detect an actuation and/or a contact of the visible or input surface (3) by an observer or operator (B); a transparent light guide (4) which, in the view of the observer or operator (B), is arranged below the visible or input surface (3), is secured to the support (12) and has an upper boundary surface (G) facing the visible or input surface (3) and a lower boundary surface (Gv) facing away from the visible or input surface (3); at least one light source (5) which is arranged to couple an optical reproduction wave field (L) into the light guide (4) via a light inlet surface (S); a first holographic image carrier (8) which contains a first transmission hologram and which is arranged adjacently to the upper boundary surface (G) of the light guide (4), wherein the reproduction wave field (L) coupled into the light guide (4) reaches the upper boundary surface (G) from the light inlet surface (S) on the basis of a light propagation produced by an internal reflection in the light guide (4), is coupled out in the direction of the observer or operator (B) and reaches the first holographic image carrier (8), wherein the reproduction wave field (L') is transformed into an image wave field (12) by the first holographic image carrier (8), and the image wave field (12) from the holographic image carrier (8) reaches the observer or operator (B) in order to display to the observer or operator (B) the first transmission hologram stored in the first holographic image carrier (8) in the form of a virtual image which visually symbolizes a switching functionality associated with the operating or display element (1) and/or an acute switching state.
