  • Floodlights are usually used for Illumination of symbols between the switch unit and the person operating the switch unit are. In particular, symbols come for one Heating regulation of a vehicle into consideration.
  • Such a known prior art has the disadvantage that the switch unit has a large number of components, namely lamp holders, lighting elements, switches and has switch guides.
  • the assembly due to the large number of individual components complex, what with high costs, especially at a Series production, is connected.
  • the invention is therefore based on the object provide electrical switch unit that with as few components as possible and simple and inexpensive way to assemble and still can be used reliably.
  • This task is done with an electrical switch unit of the type described at the outset in that the Section of the lamp holder from the switch housing protrudes and that from the switch housing protruding section as a lighting element Floodlighting of the switch housing area arranged is.
  • additional component savings can be achieved.
  • a further development according to the invention provides for this Invention sees that for the floodlights and the Function key lighting only that on the from the Switch housing protruding section of the lamp holder arranged lighting element is present, wherein at least one light guide or light guide branch available through which the light from the lighting element is the Floodlighting as function key lighting for the Function symbols arrives. This is advantageous achieved that for lighting the Switch housing environment and the function keys, or the Function symbols only require a lighting element becomes.
  • This task is also performed by a switch unit of the type described in the introduction solved that the switch unit is only one Lamp holder for one or more lighting elements has, the one lamp holder the at least one Function key and at least one movable light guide leads, which serves as a push rod for the function key.
  • This switch unit according to the invention has in particular the Advantage that due to the one, all in or on the Switch unit existing lighting elements receiving lamp holder the number of components of the Switch unit is decidedly reduced. This will also the tolerance range and tolerance fluctuations of the Switch unit greatly reduced due to fewer components. When using only one lamp holder are also fewer interfaces or between the components Liaison points that lead to vulnerabilities and thus lead to malfunctions of the switch unit can.
  • the switch unit according to the invention also has the Advantage on that by using the function keys additional components for a Function key guidance is no longer required. This also becomes a significant component reduction achieved.
  • a Movable light guide as a plunger, it is possible to To place the lighting element away from the function key, without getting any significant loss of light.
  • about the movable light guide can be a Function display lighting.
  • Such Function display lighting is used to indicate whether the Function activated via the function key on or is switched off. This allows the switch unit operating the position of the function key clearly detect.
  • the Light guide or aperture interrupting light guide branch provided, depending on the switch and / or Function key position the light guide or Optical fiber branch opens or closes. So that's one further simplification and component reduction within the Switch unit possible.
  • the lamp holder also a Provides path limitation for the function key. So that will achieved a further component reduction, resulting in lower Tolerance deviations and lower manufacturing and Assembly costs leads.
  • the Lamp holder catches for the function key.
  • the at least one function key is thus with one Lamp holder securely fixed to the switch unit.
  • the Lamp holder one or more contact springs for the Illuminates lighting elements and fixes them. That too is the use of other, cost-increasing components avoided.
  • the lamp holder Includes LED or light bulbs as lighting elements and fixed.
  • Light bulbs have the advantage that they are very inexpensive.
  • LEDs on the other hand, have a high Luminous intensity with a low heat emission.
  • the light guide and / or the Optical fiber branches are made of optical plastic. On such plastic is particularly in production and Processing cheap.
  • a variant of the invention provides that the light guide and / or light guide branches have color filters.
  • color filters can advantageously be achieved that the function key illumination is a different color has, for example, the function display or Floodlighting.
  • the color filter are interchangeable, which means for different vehicle types, which have different interior lighting colors, one and the same switch unit, with accordingly different color filters, can be used.
  • the lamp holder can advantageously be ribbed Have stabilization of the switch housing.
  • the Switch housing is mainly used to cover the Functional parts within the switch housing, in particular the lamp holder and the one held by the lamp holder Switch board.
  • the lamp holder one or more Holds switch boards and fixes them.
  • a switch board is added to the all switch contacts are arranged and of which Cables for the lighting elements come off.
  • the switch board advantageously supplies the lighting elements directly with electricity. In order to are additional lines leading to a corresponding contribute elaborate switch unit avoided.
  • the switch board connector contacts for receiving a Connector element. This is an immediate one Contacting the switch board via the plug element possible with, for example, the vehicle electrical system.
  • FIG. 1 shows an electrical switch unit 1 in Front view. Three operable are clearly recognizable Function keys 2, 3 and 4, which are within a Switch housing 7 are arranged.
  • the one shown electrical switch unit 1 is for installation in a Motor vehicle provided. With the function key 2 the Vehicle air circulation can be switched on and off.
  • Function key 3 is used to operate the air conditioning system and Function key 4 for dehumidifying a vehicle window.
