Definitions

  • the invention relates to an electric key switch, in particular an electrical key switch in a motor vehicle for operating a functional unit, with a housing and a button and a symbol illumination device for illuminating a transparent area of the button, the functional unit to be operated with the key switch or a specific function of the functional unit symbolized, and a functional illumination device for displaying the operating state of the functional unit, wherein the symbol illumination device comprises a first light source and the functional illumination device comprises a second light source and a sealed Lichtleitumble to a light integrated into the button surface.
  • Pushbuttons in motor vehicles are easy to find in the dark when a symbol on the control surface of the button is illuminated by means of a symbol lighting device.
  • the symbol is lit when the headlights of the vehicle are turned on.
  • it makes sense to inform the vehicle occupant about the current switching state of the key switch, for example, whether a functional unit is on or off.
  • an additional function lighting device can be provided with a light exit surface in the button, which is illuminated separately from the symbol illumination only in dependence on the operating state of the functional unit to be operated.
  • a push button switch is shown, which is part of a switch unit with multiple push buttons.
  • a light bulb arranged outside the housing of the switch unit serves both for external "floodlighting" of the switch unit and for illumination of the functional symbols of the individual keys. For this purpose, the light of the bulb is guided via light guide back into the housing and to the respective function symbols.
  • this design is inefficient for individual key switches and requires additional space.
  • this solution is not suitable for applications in which an external lighting of the push-button switch could be distracting.
  • a rotary transmission element for transmitting the rotational movement of a rotary knob to a rotary switch also serves to guide the rotary knob in a pressure operation and as a light guide, which transmits the light of a light source to a function light display on the front of the knob.
  • the light for a search illumination for backlighting a symbol field of the rotary knob is fed in a light guide by means of at least one light source, which is arranged on a circuit board of the key switch.
  • US 5,252,798 shows an electrical key switch with the features of the preamble of claim 1.
  • the invention provides a compact electrical key switch with efficient symbol and function illumination.
  • the Lichtleitumble comprises a light guide, and arranged over the second light source switching mat is provided, wherein between the light guide and the switching mat is a positive connection.
  • This structure allows a pleasant shift feeling in the operation of the light switch and a stray light-free entrance of the light of the second light source through the switching mat in the light guide.
  • the symbol illumination is effected by a light source arranged within the push-button switch, wherein the light-conducting path of the functional lighting is isolated from this light source and its scattered light. This ensures that neither stray light of the first light source to the light exit surface nor scattered light of the second light source can reach the transparent region of the key despite the tight space conditions.
  • the full integration of the two lighting devices in the key switch has the advantage that the key switch as stand-alone functional unit can be pre-assembled and placed anywhere in the vehicle.
  • space-saving LEDs can be used as light sources, which are preferably arranged directly on a common printed circuit board.
  • optical fiber dips into a bore of the switching mat.
  • the function of the switching mat is not affected by a movement of the light guide in the direction of actuation.
  • the formation of the light guide as a light stone, which extends from the bore of the switching mat to the button, has the advantage that the foreclosure of the Lichtleitumble can be realized by the second light source to the light exit surface in a simple manner with few components.
  • the key switch comprises a reflector which divides an interior of the key switch into two illumination areas, the first illumination area substantially restricting the exit of the light of the first light source to the transparent area and the light guide in the second Lighting area is guided.
  • the reflector thus assumes a dual function, which allows a saving of components and space.
  • the in the Figures 1 and 2 illustrated switch 10 is an electrical push button switch, which is provided in a motor vehicle for operating a specific functional unit.
  • the key switch 10 has a housing 22 and a movable key 12 with a control surface 14.
  • the control surface 14 has a transparent symbol 16, which represents the functional unit or a specific function of the functional unit.
  • Above the symbol 16 is a light exit surface 18, via which the vehicle occupant is informed about the operating state of the functional unit.
  • the housing 22 and / or the button 12, which are each made here in one piece, can also be composed of several parts.
  • FIG. 2 the structure of the key switch 10 can be seen.
  • the button 12 is fixedly connected to a reflector 20 which is guided in a housing 22 and sits on domes 24, 26 of a switching mat 28.
  • the switching mat 28 in turn rests on a printed circuit board 30.
  • the dome 24, 26 of the switching mat 28 are compressed by the reflector 20 and thus provide a certain feel, which is perceived by the vehicle occupant.
  • the switching mat 28 two light sources 32, 34 are arranged in the form of LEDs.
  • the first light source 32 which is arranged in a bore 36 of a projecting into the reflector 20 survey 38 of the switching mat 28, is used when needed to illuminate the symbol 16.
  • the second light source 34 is disposed in a bore 40 of the mandrel 26 and is dependent the switching state of the key switch 10 is activated.
  • the reflector 20 divides an internal space of the key switch 10 in two lighting areas, wherein the subdivision is substantially realized by a partition wall 42.
  • the first illumination region is geometrically designed so that the light of the first light source 32 entering the reflector 20 via the bore 36 of the projection 38 uniformly illuminates the transparent symbol 16.
  • a light brick 44 is held, which extends from the control surface 14 of the key 12 into the bore 40 of the mandrel 26, in which the second light source 34 is arranged.
  • the second light source 34 facing away from the end of the light brick 44 forms the light exit surface 18 in the control surface 14 of the button 12, which indicates the vehicle occupant current switching state of the push-button 10.
  • the light brick 44 is fixedly connected to the button 12 or to the reflector 20 and is accordingly moved along with an actuation of the push-button 10 with these.
  • the second light source 34 facing the end of the light brick 44 moves in the bore 40, without thereby the flexibility of the switching mat 28 is hindered in the direction of actuation.
  • another light guide or a correspondingly formed light shaft can be provided.
