  • the invention relates to a rotary knob, in particular as Control element for motor vehicle components, with a rotatable arranged handle, one firmly connected to the handle and with this rotatable first carrier plates, one fixed second carrier plate, electrically conductive Fasteners for the production of an electrical Connection between the first and the second carrier plate and an electric light source.
  • Illuminated knobs are used in various devices. By illuminating the rotary knob this can be recognized even in the dark. Is the illuminable Part of the knob located outside the center, see above can clearly the position of the rotary knob at the same time be recognized. This is particularly important if the rotary knob with a clickable switching or adjusting element connected is. In such a case at the various Locking positions of the rotary knob an even Luminosity is known to have several Arrange the LEDs in a ring underneath the rotary knob. So the screening takes place on the Rotary knob radially from the center of the symbol or Marking element in the different locking positions each with its own light emitting diode. The disadvantage is this embodiment that a variety of light emitting diodes is required.
  • a rotational resistance is known from DE 197 12 294 C2, which has an illuminated rotary knob.
  • a light emitting diode is mounted on a fixed board.
  • the rotational resistance has a light guide body, in whose center of rotation is a light entry surface in front of the light source is arranged.
  • the light guide body ends in a transparent housing part, one from the outside visible scale. Such an arrangement is therefore especially for large-area lighting of the rotary knob suitable.
  • the object of the invention is to provide a rotary knob, which is an illuminated function symbol or an illuminated one Marking with a single light source to illuminate the function symbol or the marking gets along and still a uniform illuminance the function symbol or the marking for different ones Guaranteed rotary positions of the rotary knob.
  • the task is done with a generic knob solved that the electric light source on the first Carrier plate is arranged and over the connecting elements is supplied with an operating voltage.
  • a design is realized in which the light source is integrated directly into the rotary knob and works with it rotates. It thus becomes a central arrangement of the light source below a radiolucent area of the rotary knob allows. This ensures that the illuminance regardless of the rotary position of the rotary knob is always constant.
  • the translucent area is concerned it is particularly a translucent outdoor area the handle, preferably a translucent one Function symbol or a mark, the outside area can be X-rayed by the light source and in Distance to an axis of rotation of the handle is arranged. With Such an arrangement can position even in the dark of the rotary knob can be reliably recognized. This is particularly so when operating components in a motor vehicle of importance, so that here is a preferred area of application for the rotary knob according to the invention.
  • the arrangement of the light source within the rotary knob can be used to illuminate the radiolucent area be quite sufficient, but the handling of the rotary knob according to the invention preferably an optical fiber with a light entry surface facing the light source on. Through this light guide the light becomes the light source from this to the illuminated area.
  • the arrangement of the light source in the knob itself can Light guide a simple geometric shape such as have a rod or cylindrical shape. Through this simple design of the light guide can cost of such a knob can be kept low.
  • the connecting elements are preferably between the first and second carrier plate designed as a contact spring grinder, which are attached to the fixed, second carrier plate are.
  • an operating element can be realized with a large angle of rotation, especially with a rotation angle of more than 360 Degrees (endlessly rotatable).
  • the first points Carrier plate preferably each self-contained Conductor tracks on that with the light source and the connecting elements are connected. The closed, in contact Conductor tracks to the contact spring wipers are still arranged concentrically to each other.
  • the connecting elements between the first and second carrier plate for example, also formed as a cable his.
  • the first carrier plate is in particular ring-shaped and arranged concentrically to the handle. hereby is achieved that an adjusting axis of the rotary knob by reach through the first carrier plate and onto a positioning or Switching element can act.
  • a switching or The control element is preferably on the second carrier plate arranged. Examples of corresponding switching or Control elements are a latching rotary switch, a rotary potentiometer, an incremental encoder or an encoder.
  • the first carrier plate joined together with the light guide. This results in a safe and permanently stable Connection of the light guide within the rotary knob.
  • the light guide is particularly non-positive and positive connected to the handle.
  • the light source is in particular a Led. These components are small and available for mounting on printed circuit boards.
