Definitions

  • the invention relates to a membrane key switch with a housing and a displaceably guided on the housing key.
  • Modern membrane push-button switch as used in particular in motor vehicles, are short-stroke and have an illuminated keypad when needed. They consist of a plastic housing and a mounted and guided button. Below the button is a connector chamber in which a generally multi-pin connector is inserted and locked. The plug chamber occupies a large part of the generally predetermined total height of the switch, which leaves little height for the leadership of the key.
  • the invention provides a membrane key switch is provided in which the key guide can extend over almost the entire height of the switch.
  • the housing has an outer wall which extends to a surface remote from the key base, is angled inwardly of the base and merges into an inner wall angled parallel to the outer wall forming a plug chamber;
  • the button has at least one molded guide wall which is arranged between the inner wall and the outer wall of the housing.
  • the guide wall of the key thus surrounds the plug chamber so that the height of the plug chamber does not limit the length of the key guide. In the preferred embodiment, therefore, the guide wall of the button extends to near the base of the housing.
  • the inner wall of the housing at its end facing the button in an angled upper wall over.
  • a circuit board can be arranged, are constructed on the functional elements of the membrane key switch, in particular a means of the button actuated membrane switch element and an optional illuminated switch symbol.
  • the membrane key switch shown in the figures comprises a housing 10 made of plastic, the shape of which is generally cylindrical, with a cross-sectional shape resembling a rectangle with rounded corners.
  • a button 12 also made of plastic, is arranged on the housing 10.
  • the button 12 has a touch surface 12a and a one-piece molded guide wall 12b.
  • the housing 10 consists of an outer wall 10a which extends between an upper edge facing the key 12 and a base, where it is angled inwardly, an inner wall 10b extending from the inwardly angled portion of the outer wall 10a and extends parallel to the outer wall in the direction of the key 12, and an upper wall 10c, which is parallel to the sensing surface 12a. All components of the housing 10, outer wall 10a, inner wall 10b and upper wall 10c, are integrally molded with each other, in particular by injection molding. The inner wall 10b of the housing is limited with the upper wall 10c a connector chamber 14, projecting into the contact pins 16.
  • the contact pins 16 penetrate the upper wall 10c and are connected to a circuit board 18 which is disposed between the key 12 and the upper wall 10c of the housing parallel thereto.
  • a circuit board 18 which is disposed between the key 12 and the upper wall 10c of the housing parallel thereto.
  • various functional elements of the membrane key switch are constructed. These include switch contacts, lighting elements, electronic components and the like.
  • Between the button 12 and the circuit board 18 are optical and mechanical transmission elements.
  • the outer wall 10a and the inner wall 10b of the housing 10 have a radial distance from each other.
  • the guide wall 12 b of the key 12 is inserted in the space thus formed between the outer wall 10 a and inner wall 10 b.
  • This guide wall 12b extends between outer wall 10a and inner wall 10b to close to the base 10d of the housing 10, where the inner wall and the outer wall are connected to each other.
  • the distance a between the end of the guide wall 12b and the base of the housing 10 is slightly larger than the intended key stroke.
  • intermeshing guide structures in the form of ribs and channels are formed on the inside of the outer wall 10a and on the outer side of the guide wall 12b.
  • a rib 20 is formed, which engages between two adjacent ribs 24, 26, which are integrally formed on the outside of the guide wall 12 b of the key 12.
  • a similar guide structure with an integrally formed rib 28 on the inside of the outer wall 10a is provided, which engages in a channel on the outside of the guide wall 12b.
  • guide ribs 30, 32 are integrally formed on the outside of the guide wall 12b and extend perpendicular to the guide ribs 20 and 28, so that the key 12 is supported largely free of play in two mutually perpendicular directions and perpendicular to its axis.
  • a rib 22 is integrally formed on the outer wall 10a and serves as a rotation in the assembly of the key 12th
  • a circumferential support collar 38 is integrally formed on the outside of the outer wall 10a. With this support collar 38, the axial position of the housing 10 is fixed to the diaphragm 36.
  • locking lugs 40 are formed, which engage in corresponding recesses 42 of the guide wall 12b of the key 12 to lock the key with the required for the key stroke game on the housing 10.
