The invention relates to an operating or visualising element, comprising: an input part or visualising part (2) forming a translucent or transparent input surface or visualising surface (3); a carrier (12) for securing the operating or visualising element to an external structure; a detection device (13) which is designed to detect an actuation and/or a contacting of the input surface or visualising surface (3) by the operator (B); a transparent light guide (4) which, as viewed by the operator (B), is arranged below the input surface or visualising surface (3) and secured to the carrier (12), and which has an upper boundary surface (G) facing the input surface or visualising surface (3) and a lower boundary surface (G') facing away from the input surface or visualising 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 entry surface (S); a holographic image carrier (8), including a hologram, which is arranged adjacent to the upper boundary surface (G) of the light guide (4) or adjacent to the lower boundary surface (G') of the light guide (4), wherein the reproduction wave field (L) coupled into the light guide (4) travels from the light entry surface (S) to the upper boundary surface (G) due to a light propagation brought about via internal reflection in the light guide (4), is out-coupled in the direction of the operator (B) and travels to the holographic image carrier (8), wherein the first reproduction wave field (L) is transformed into an image wave field (L') by the first holographic image carrier (8) and the image wave field (L') travels from the holographic image carrier (8) to the operator (B), in order to display the hologram stored in the holographic image carrier (8) to the operator (B) as a virtual image, which contains a symbol (6) in a display surface (16) for visualising the switching functionality associated with the operating or visualising element (1) and/or a current switching status of the operating or visualising element (1), wherein the display surface (16) extends non-parallel to the upper boundary surface (G) and non-parallel to the lower boundary surface (G').
