Je nach gewählten Schaltfunktionen der Funktionstasten können diese, beziehungsweise eine von der Funktionstaste angesteuerte Mechanik und/oder Elektronik, unterschiedlich ausgebildet sein. Dies macht die bekannten Schaltereinheiten im Aufbau sehr aufwändig.Such switch units are available in a variety of ways known. Depending on the selected switching functions of Function keys can this, or one of the Function key controlled mechanics and / or electronics, be formed differently. This makes the known Switch units in construction very complex.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Schaltereinheit vorzuschlagen, die möglichst eine große Anzahl verschiedener Schaltfunktionen durchführen kann, wobei der Aufbau der Schaltereinheit insgesamt flexibel und einfach sein soll.The present invention is therefore based on the object to propose a switch unit, the possible a large Number of different switching functions can perform, where the structure of the switch unit as a whole flexible and easy should be.

Diese Aufgabe wird mit einer Schaltereinheit gelöst, bei der jeder Funktionstaste eine separate Einzelleiterplatte mit einer entsprechenden Mechanik und/oder Elektronik zugeordnet ist, wobei ein Grundelement vorgesehen ist, auf dem die Einzelleiterplatten angeordnet sind, und wobei grundelementseitige Leiterbahnen vorgesehen sind, deren freien Enden als Kontaktfedern ausgebildet sind und einzelleiterplattenseitige Kontakte federnd vorgespannt kontaktieren. Durch eine derartige Schaltereinheit kann vorteilhafterweise erreicht werden, dass je nach Schaltaufgabe unterschiedliche Funktionstasten mit unterschiedlichen Einzelleiterplatten in der Schaltereinheit Verwendung finden können. Über die Kontaktfedern am Grundelement kann auf einfache Art und Weise eine funktionssichere Kontaktierung der Einzelleiterplatten erfolgen. Je nach zu bewältigender Schaltaufgabe können unterschiedliche Funktionstasten und/oder Einzelleiterplatten mit unterschiedlicher Bestückung Verwendung finden. Eine derartige Schaltereinheit ist unabhängig von den zu bewältigenden Schaltaufgaben sehr flexibel einsetzbar.This object is achieved with a switch unit in which Each function key has a separate single-conductor plate associated with a corresponding mechanics and / or electronics is, wherein a basic element is provided, on which the Single-conductor plates are arranged, and wherein Element-side conductor tracks are provided, the free Ends are formed as contact springs and Single-core plate-side contacts spring-biased to contact.

In diesem Zusammenhang ist ferner vorteilhaft, wenn die Abmessungen der Einzelleiterplatten wenigstens weitgehend gleich sind. Die Bestückung, und damit die Schaltfunktion der einzelnen Leiterplatten, kann allerdings unterschiedlich sein. Beispielsweise ist denkbar, dass für jede Einzelleiterplatte drei Kontaktfedern am Grundelement vorgesehen sind Ob die mit den drei Kontaktfedern zu kontaktierende Leiterplatte tatsächlich auch drei Kontaktstellen aufweist, hängt von der zu bewältigenden Schaltaufgabe ab. Denkbar ist, dass lediglich zwei Kontakte für die drei Kontaktfedern vorgesehen sind; eine der Kontaktfedern kontaktiert dann keinen vorgesehenen Kontakt an der Einzelleiterplatte.In this context, it is also advantageous if the Dimensions of the individual conductor plates at least largely are the same. The equipment, and thus the switching function of individual circuit boards, however, may be different. For example, it is conceivable that for each single-conductor plate three contact springs are provided on the base element Whether the with the three contact springs to be contacted circuit board actually has three contact points, depends on the to be handled switching task.
