This switch can according to figure 2 for example in an operating panel below the display device of a watch case can be used. According to Figure 4 has the switch used a rubber part from a electrically conductive elastomer depending on pressure. With this Rubber part is connected to a so-called switch body, which fixed contacts for electrical contacting the Has switch.

Die Aufgabe der Erfindung liegt darin, ein Bedien-Tableau mit einem Schalter anzugeben, welches sich vergleichsweise einfach herstellen lässt.The object of the invention is to have an operating panel specify a switch, which is comparatively easy can be made.
Die Aufgabe wird dadurch gelöst, dass die Festkontakte in das aus Kunststoff gefertigte Bedien-Tableau integriert sind und das Schaltelement mit diesem im Mehrkomponenten-Spritzgießverfahren hergestellt ist. Hierdurch entsteht vorteilhafterweise ein einfach herzustellendes Bauteil, wobei durch die Anwendung des Mehrkomponenten-Spritzgießverfahrens eine Endmontage eingespart wird. Besonders vorteilthaft ist es, wenn auch die Festkontakte bildende Leiterbahn aus leitfähigem Kunststoff zusammen mit dem Bedien-Tableau und dem Schaltelement im Mehrkomponenten-Spritzgießverfahren hergestellt sind. Hierdurch können zusätzlich die Festkontakte und die sich an diese anschließenden Leiterbahnen kostengünstig im Spritzgießverfahren zusammen mit den anderen spritzgegossenen Komponenten hergestellt werden. Hierdurch ergibt sich ein besonders kostengünstiges Bedien-Tableau.The task is solved in that the fixed contacts in the control panel made of plastic are integrated and the switching element with this in a multi-component injection molding process is made. This advantageously results an easy to manufacture component, with the Final assembly using the multi-component injection molding process is saved. It is particularly advantageous if also the conductor track forming conductive contacts made of conductive Plastic together with the control panel and the switching element manufactured in a multi-component injection molding process are. As a result, the fixed contacts and to these connecting conductor tracks inexpensively in Injection molding process along with the other injection molded ones Components are manufactured. This results in a special one cost-effective control panel.
Weiterhin ist es vorteilhaft, wenn dass Bedien-Tableau einen Wandlungsteil eines Gehäuses für elektronische Bauteile bildet. Dabei kann vorteilhaft der Schalter des Bedien-Tableaus elektrisch mit den elektronischen Bauteilen verbunden werden. Außerdem kann besonders vorteilhaft das Gehäuse als Schaltungsträger für die elektronischen Bauteile verwendet werden. Dabei kann für die elektronischen Bauteile sowie den Schalter auf eine gesonderte Trägerplatte komplett verzichtet werden, wodurch zum einen die Fertigungskosten reduziert werden und zum anderen eine besonders kompakte Bauweise des Gehäuses realisiert wird.It is also advantageous if the control panel has a Conversion part of a housing for electronic components forms. The switch on the control panel can be advantageous be electrically connected to the electronic components. In addition, the housing can be particularly advantageously used as a circuit carrier can be used for the electronic components. It can be used for the electronic components as well as the switch there is no need for a separate carrier plate, which on the one hand reduces the manufacturing costs and on the other hand, a particularly compact design of the housing is realized becomes.
Das Bedien-Tableau kann beispielsweise mittels einer Steckverbindung mit dem Gehäuse verbunden werden und dabei beispielsweise gleichzeitig die Funktion eines Deckels für eine Gehäuseöffnung übernehmen, welche zum Einbau der elektronischen Bauteile in das Gehäuse vorgesehen ist. Besonders vorteilhaft ist jedoch die einteilige Herstellung des Gehäuses und des Bedien-Tableaus durch Spritzgießen.The control panel can, for example, by means of a plug connection be connected to the housing, for example at the same time the function of a lid for one Take over the housing opening, which is used to install the electronic Components are provided in the housing. Particularly advantageous is, however, the one-piece manufacture of the housing and the control panel by injection molding.
Als elektrisch leitender Kunststoff wird zweckmäßig ein Compound aus Metallpulver und einem thermoplastischen Elastomer eingesetzt. Entscheidend für die Funktion gefüllter leitfähiger Compounds ist, daß sich ein durchgehendes Netzwerk ausbildet, in dem sich die Füllstoffpartikel berühren bzw. auf ca. 10 nm annähnern. Bei einer kontinuierlichen Steigerung des Füllstoffanteils steigt die Leitfähigkeit zunächst nur geringfügig bis zu einer bestimmten Konzentration a. In einem schmalen Konzentrationsbereich oberhalb einer bestimmten Füllstoffkonzentration, der sogenannten Perkolationskonzentration, steigt die Leitfähigkeit dann um ein Vielfaches an. Bei einer weiteren Steigerung der Füllstoffkonzentration wird ein Plateauwert erreicht, ab dem sich die Leitfähigkeit nicht mehr deutlich verändert. Dieser Plateauwert ist im wesentlichen von der Form der Füllstoffpartikel und deren Neigung zur Agglomeration von Netzwerken abhängig, aber auch z. B. von Störungen der statistischen Füllstoffverteilung.A compound is expediently used as the electrically conductive plastic made of metal powder and a thermoplastic elastomer used. Crucial for the function of filled conductive Compounds is that a continuous network is formed in which the filler particles touch or on approximate approx. 10 nm. With a continuous increase the proportion of filler initially only increases slightly up to a certain concentration a. In one narrow concentration range above a certain Filler concentration, the so-called percolation concentration, The conductivity then increases many times over on. With a further increase in the filler concentration a plateau value is reached, above which the conductivity no longer changed significantly. This plateau value is essentially on the shape of the filler particles and their inclination depending on the agglomeration of networks, but also e.g. B. of disturbances in the statistical filler distribution.
Liegt die Füllstoffkonzentration im Anfang des Perkolationsbereiches, so kommt es bei Druckeinwirkung auf den Kunststoff zu einem sprunghaften Ansteigen der elektrischen Leitfähigkeit. Diese Eigenschaft lässt sich zur Realisierung einer Tasterfunktion nutzen. Werden am Gehäuse mechanische Mittel zum Einrasten in der betätigten Stellung vorgesehen, so kann auch eine Schalterfunktion wie bei einem Kippschalter realisiert werden.If the filler concentration is in the beginning of the percolation range, so it comes under pressure on the plastic to a sudden increase in electrical conductivity. This property can be used to implement a Use button function. Are mechanical means on the housing provided to snap in the actuated position, so can also a switch function like a toggle switch become.
Sämtliche Montagearbeiten für den Schaltereinbau entfallen mit der erfindungsgemäßen Lösung. Werden auch die Leitungsverbindungen im Mehrkomponentenspritzgießverfahren mit hergestellt, so entfallen sogar die Arbeiten zur Herstellung der nötigen Leitungsverbindungen.All installation work for the switch installation is omitted with the solution according to the invention. Will also be the line connections manufactured in a multi-component injection molding process, this even eliminates the work required to manufacture the necessary line connections.
Der Schalter ist äußerst robust, da er aus einem einheitlichen Werkstoff besteht und mechanische Teile entfallen. Außerdem sind keine Gehäusedurchbrüche für den Schalter nötig, so dass nunmehr auf einfache Art und Weise Gehäuse hergestellt werden können, die dicht sind gegenüber aggressiven Medien oder gegenüber Staub.The switch is extremely robust as it is made from a single unit Material exists and mechanical parts are omitted. Moreover no openings for the switch are necessary, so that housings are now produced in a simple manner that are dense to aggressive Media or against dust.
