Definitions
- the invention relates to a membrane key switch with a housing and a key that is slidably guided on the housing.
- Modern membrane pushbutton switches as used in particular in motor vehicles are used, are short-stroke and have an illuminable if necessary Keypad. They consist of a plastic housing and a key attached to it and guided. Located below the button there is a connector chamber in which a generally multi-pin connector is used and locked. The connector chamber takes a large one Part of the generally specified total height of the switch, which means that there is little overall height for guiding the button.
- the invention provides a membrane push button switch, where the key guide extends over almost the entire height of the switch can extend.
- the housing has an outer wall that extends up to extends to a base surface facing away from the key, on the Base is angled inwards and into a parallel to the outer wall angled inner wall merges, which forms a plug chamber;
- the button has at least one molded guide wall, which between the inner wall and the outer wall of the housing is arranged.
- the Guide wall of the key thus surrounds the connector chamber, so that the height the plug chamber is not a limitation on the length of the button guide. In the preferred embodiment, therefore, the Guide wall of the key close to the base of the housing.
- a further improvement of the key guide is the preferred Embodiment achieved in that the inside of the outer wall of the Housing and on the outside on the guide wall of the button guide ribs and corresponding guide channels are formed.
- the inner wall of the housing at its end facing the button into an angled upper Wall over.
- a circuit board can be placed between the button and the top wall be arranged on the functional elements of the membrane switch are constructed, in particular one which can be actuated by means of the key Membrane switch element and an optional illuminated switch symbol.
- the membrane key switch shown in the figures has a housing 10 made of plastic, the shape of which is generally cylindrical, with a Cross-sectional shape that resembles a rectangle with rounded corners.
- a button 12 also made of plastic, is arranged on the housing 10.
- the key 12 has a key surface 12a and an integral part Guide wall 12b.
- the housing 10 consists of an outer wall 10a, which is located between an upper button 12 facing Edge and a base extends and angled in there is, an inner wall 10b, which is from the inwardly angled area the outer wall 10a goes out and parallel to the outer wall in the direction the button 12 extends, and an upper wall 10c which is parallel to the Touch surface 12a is. All components of the housing 10, outer wall 10a, Inner wall 10b and upper wall 10c are integrally formed with one another, especially by injection molding.
- the inner wall 10b of the housing delimits with the upper wall 10c, a connector chamber 14, into the contact pins 16 protrude.
- the contact pins 16 penetrate the upper one Wall 10c and are connected to a circuit board 18 which between the button 12 and the upper wall 10c of the housing parallel to this is arranged.
- Various functional elements are on the printed circuit board 18 membrane switch. This includes 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 one radial distance from each other.
- the guide wall 12b Key 12 inserted in the so between the outer wall 10 a and The inner wall 10b formed intermediate space.
- This guide wall 12b extends between Outer wall 10a and inner wall 10b close to the base 10d of the Housing 10, where the inner wall and outer wall are connected.
- the distance a between the end of the guide wall 12b and the base the housing 10 is slightly larger than the intended key travel.
- Further guide ribs 30, 32 are on the Molded outside of the guide wall 12b and extend vertically to the guide ribs 20 and 28 so that the button 12 in two directions perpendicular to one another and perpendicular to their axis largely is supported without play. Furthermore, a rib 22 is on the inside the outer wall 10a integrally formed and serves as an anti-rotation device in the Installation of the button 12.
- latching arms 34 integrally formed, by means of which the membrane key switch in one Opening an aperture 36 or the like is locked.
- a circumferential Support collar 38 formed on the outside of the outer wall 10a. With this Support collar 38 is the axial position of the housing 10 on the Aperture 36 set.
- Lugs 40 are formed on the inside of the outer wall 10a into corresponding recesses 42 in the guide wall 12b of the button 12 intervene to the key with that required for the key stroke Lock game on the housing 10.
