Die Polymerisation der Pyrrole erfolgt in Gegenwart von Komplexierungsraitteln. Man versteht hierunter Salze, die als Anionen beispielsweise solche aus der Gruppe BF^", AsF^", AsF6"", SbFg", SbCl", PFg", ClO^, HSO4", SOa enthalten. Bevorzugt sind auch Koraplexierungsraittel, die Anionen aromatischer Sulfonsäuren,' beispielsweise das Benzolsulfonsäure-Anion oder Toluolsulfonsäure-Anion enthalten. Diese Salze enthalten als Kationen z.B. Lithium, Natrium oder Kalium oder auch tertiäre oder quaternäre Ammonium- oder Phosphonium-Kationen. Die Verwendung von Verbindungen dieser Klasse als Koraplexierungsmtttel ist bekannt. Diese Koraplexierungsmittel, die bei der elektrochemischen Polymerisation der Pyrrole gleichzeitig als Leitsalze dienen, werden hierbei in die Pyrrol-Polymeren eingelagert und bewirken die hohe elektrische Leitfähigkeit der- Pyrrol-Polymeren.

This is understood to mean salts which contain as anions, for example, those from the group BF ^ ", AsF ^", AsF 6 "", SbFg ", SbCl", PFg ", ClO ^, HSO 4 ", SOa. Coraplexing agents which contain anions of aromatic sulfonic acids, for example the benzenesulfonic acid anion or toluenesulfonic acid anion, are also preferred. These salts contain, for example, lithium, sodium or potassium or also tertiary or quaternary ammonium or phosphonium cations as cations. The use of compounds of this class as coraplexing agents is known. These coraplexing agents, which also serve as conductive salts in the electrochemical polymerization of the pyrroles, are incorporated into the pyrrole polymers and cause the pyrrole polymers to have high electrical conductivity.

In der Figur ist eine mögliche Ausführungsform des erfindungsgemäßen Druckschalters im Querschnitt schematisch wiedergegeben. Auf einer festen, dimensionsstabilen Unterlage (1), z.B. aus Kunststoff, Glas, Metall, Papier oder ähnlichem, sind zwei flächig ausgebildete Kontaktelemente (2) aus elektrisch leitfähigen Pyrrol-Polymeren über eine elektrisch isolierende Haftschicht (3) festhaftend aufgebracht. Die beiden Kontaktelemente (2) sind dabei elektrisch voneinander getrennt angeordnet und jeweils, mit einem Anschluß (A) für die Strorazu- bzw. -abfuhr- versehen, über den beiden Kontaktelementen (2) ist das ebenfalls flächig ausgebildete, federnde Brückeneleraent (5) aus den elektrisch leitfähigen Pyrrol-Polymeren mittels geeigneter Halte- oder Einspannvorrichtungen (6) so angebracht, daß es von beiden Kontakteleraenten (2) elektrisch getrennt ist. Dies erfolgt in der gezeigten Ausführungsform über Isolierelemente (7), wobei auch die beiden Kontaktelemente über ein solches Isolierelement (7) getrennt sind. Durch ein Druck erzeugendes Mediun (8), z.B. die menschliche Hand oder ein mechanisches Druckstück wi-e einen Stempel, kann das Brückeneleraent (5) an die beiden Kontaktelemente (2) angedrückt und so zwischen diesen eine elektrisch leitende Verbindung hergestellt werden. Wird das Brückeneleraent (5) wieder von dem Druck entlastet, geht es aufgrund' seiner federnden, elastischen Eigenschaften unter Unterbrechung der elektrisch leitenden Verbindung wieder in seine Ausgangslage zurück.In the figure is a possible embodiment of the invention Pressure switch shown schematically in cross section. On a firm, dimensionally stable base (1), e.g. made of plastic, glass, Metal, paper or the like are two flat contact elements (2) made of electrically conductive pyrrole polymers via an electrically insulating adhesive layer (3) applied firmly. The two contact elements (2) are arranged electrically separated from one another and each with a connection (A) for the power supply or discharge, Above the two contact elements (2) is the resilient bridge element (5), which is also flat, made of the electrically conductive Pyrrole polymers using suitable holding or clamping devices (6) attached so that it is electrically isolated from both Kontakteleraenten (2) is. In the embodiment shown, this takes place via insulating elements (7), the two contact elements also being separated by such an insulating element (7). Through a pressure generating medium (8), E.g. the human hand or a mechanical pressure piece wi-e one Stamp, the bridge element (5) can be attached to the two contact elements (2) pressed and so an electrically conductive connection can be established between them. If the bridge element (5) is back from the pressure relieved, it works because of 'its resilient, elastic properties back to its original position with interruption of the electrically conductive connection.

Auch wenn der erf inclungsgemäße Druckschalter an Hand der . in der Figur gezeigten speziellen Ausführungsform erläutert worden ist, so ist es selbstredend, daß er viele andere Ausgestaltungsformen besitzen kann, wie sie für Druckschalter der in Rede stehenden Art üblich bzw. für einen 0.5 Fachmann selbstverständlich und geläufig sind.Even if the pressure switch according to the invention is based on the. in the figure Shown specific embodiment has been explained, it goes without saying that it can have many other embodiments, such as they are common for pressure switches of the type in question or for one 0.5 are a matter of course and familiar to a person skilled in the art.
So können die beiden Kontaktelemente - wenn auch bevorzugt - nicht nur flächig ausgebildet sein, sondern beispielsweise· auch linienförmig oder zylindrisch· Je nach Anordnung des Brückenelementes und der beiden Kontakteleraente kann auf besondere Isolierelemente dazwischen verzichtet werden, sofern durch andere konstruktive Auführungsformen das Erfordernis der elektrisch voneinander getrennten Anordnung dieser Elemente gewährleistet ist. In einer anderen Ausgestaltungsform des er.findungsgemäßen Druckschalters kann z.B. das Brückenelement fest mit einem der Kontaktelemente elektrisch leitend verbunden sein, so daß durch den Druck auf das Brückeneleraent nur noch der Kontakt mit dem zweiten Kontaktelement hergestellt zu werden braucht. Ferner ist es möglich, das federnde Brückenelement so anzuordnen, daß es nicht durch Druck, sondern durch Zu;·; an das bzw. die Kontaktelement(e) angedrückt wird. Eine Haftschicht zum Anbringen der Kontaktelemente auf einer Unterlage ist ebenfalls keineswegs zwingend erforderlich bzw. kann durch andere äquivalente Mittel ersetzt werden.So the two contact elements can - even if preferred - not only be flat, but also, for example, linear or cylindrical · Depending on the arrangement of the bridge element and the two contact elements, special insulating elements in between can be dispensed with if the requirement is met by other constructive forms of execution the electrically separated arrangement of these elements is guaranteed. In another embodiment of the inventive Pressure switch, for example, the bridge element can be firmly connected to one of the contact elements in an electrically conductive manner, so that the pressure on the bridge element only has contact with the second contact element needs to be produced. It is also possible to arrange the resilient bridge element in such a way that it is not by pressure, but by to; ·; is pressed against the contact element (s). An adhesive layer for Attaching the contact elements to a base is also by no means absolutely necessary or can be done by other equivalent means be replaced.
Das Brückeneletnent kann zum Auslösen des Schaltvorganges direkt mit Λο·λ Druck oder Zug erzeugenden Medium in Kontakt gebracht werden. Es kann aber auch beispielsweise von einer flexiblen, vorzugsweise elektrisch isolierend wirkenden Abdeck- oder Schutzfolie, beispielsweise aus Kunststoff, überspannt sein. Das Brückenelement kann auch als mehrlagiges Element ausgestaltet sein mit einer Lage aus den elektrisch..leitenden Pyrrol-Polytaeren, die den Kontaktelementen zugewandt ist, und einer Lage aus ε.3· einem elektrisch isolierend wirkenden Material, etwa einen ande~ ren Kunststoff-Film, die dem Druck erzeugenden t'ediun zugewandt ist. n;u; Brückenelement bzw. die sie überspannende Abdeck- bzw. Schutzfolie kann auch als Membran ausgebildet sein, so daß als druckerzeügendes 'Medium auch Gase oder Flüssigkeiten Anwendung finden können. Schließlich kann der erfindungsgemäße Druckschalter auch in ein SchaLt- oder Isoliergehäuse eingebaut sein.To trigger the switching process, the bridge element can be brought into direct contact with Λο · λ pressure or tension generating medium. However, it can also be covered, for example, by a flexible, preferably electrically insulating covering or protective film, for example made of plastic. The bridge element can also be designed as a multi-layer element with a layer made of the electrically conductive pyrrole polythene facing the contact elements and a layer made of an electrically insulating material, such as another plastic film facing the pressure generating t'ediun. n; u; The bridge element or the covering or protective film that spans it can also be designed as a membrane, so that gases or liquids can also be used as the pressure-generating medium. Finally, the pressure switch according to the invention can also be built into a switch or insulating housing.
Der erfindungsgemäße Druckschalter kann aufgrund seiner vielfältigen w'>\\~
liehen Ausgestaltungsformen in vielen Anwendungsbereichen Einsatz finden.
Er besitzt eine hohe Lebensdauer. Mit einem Druckschalter, wie er in der
Figur dargestellt ist, konnten über 20 Millionen Schaltungen ohne sichtbare Materialermüdungen ausgeführt werden.
Zeichn.The pressure switch according to the invention can be found due to its diverse w '> \\ ~ borrowed embodiments in many applications use. It has a long service life.
