A control element for control functions within a passenger area of a vehicle having several turning knobs whose positions are indicated by an illumination display, includes an LED (Light Emitting Device) and a light-guide coupled directly with the LED and having a light-exit surface that is coupled with a light-entry surface leading to at least one turning knob, a light-conducting plate (7) adjacent the light-guide, and a housing. The light guide (4) is connected with the turning knob (2) and has, on axial surfaces (8,9) at an outer rim (10), indexing bumps and indexing indentations (11, 12), respectively, that cooperate with retaining catches (13) of a retaining spring (14) that is pushed onto the light-conducting plate (7) within retaining ribs (15) and is locked between an edge of the light-conducting plate (16) and a housing rib (17) in the push-on
An illuminated knob assembly includes a base. The base includes an annular track on an upper base surface of the base. A PC board is disposed in the track. The PC board includes a plurality of light sources disposed on an upper board surface of the board. A light transmitting plate is positioned over the PC board so as to transmit light therethrough from the light sources. A bezel is fitted over the light transmitting plate and includes gradated openings corresponding to different conditions of operation. The openings permit light to pass therethrough from the light transmitting plate and a knob is disposed adjacent the bezel. The knob includes a light pointer configured to receive and transmit light from the light transmitting plate.
