Zudem ist durch die DE 102 33 331 C1 ein weiteres elektrisches Schaltgerät bekannt geworden. Dieses elektrische Schaltgerät besteht im Wesentlichen aus einem wannenförmig ausgebildeten Sockelteil zur Aufnahme einer elektrischen Leiterplatte, auf welcher die zur Realisierung der geforderten Funktionen notwendigen elektrischen/elektronischen Bauelemente angeordnet sind und wobei zur Funktionsbeeinflussung als Benutzerschnittstelle zumindest ein Betätigungsorgan vorgesehen ist. Der Aufbau eines solchen elektrischen Schaltgerätes ist durch die Berücksichtigung von Modularitätsaspekten schon stark vereinfacht. Trotzdem verursacht der Aufbau eines solchen elektrischen Schaltgerätes immer noch einen erheblichen Herstellungs- und Montageaufwand.In addition, through the DE 102 33 331 C1 Another electrical switching device has become known. This electrical switching device consists essentially of a Trough-shaped base part for receiving an electrical circuit board on which the required for the realization of the required functions electrical / electronic components are arranged and wherein at least one actuating member is provided to function as a user interface. The construction of such an electrical switching device is already greatly simplified by the consideration of modularity aspects. Nevertheless, the structure of such an electrical switching device still causes a considerable manufacturing and assembly costs.

Außerdem ist durch die DE 84 19 690 U1 ein elektrisches Schaltgerät mit einem wannenförmig ausgebildeten Sockelteil zur Aufnahme einer Bodenplatte bekannt geworden. Auf der Bodenplatte sind einige der zur Realisierung der geforderten Funktionen notwendigen elektrischen/elektronischen Bauteile angeordnet, wobei zur Funktionsbeeinflussung als Benutzerschnittstelle zumindest ein Betätigungsorgan vorgesehen ist. Das Betätigungsorgan besteht aus einem, den Innenraum des Sockelteiles oberseitig verschließenden Grundkörper, einem auf der dem Sockelteil abgewandten Hauptfläche angeordneten, aus zumindest zwei Schichten bestehenden Glasplattenverbund mit Flächenelektroden und einer Füllung mit Flüssigkristall sowie einer, den Grundkörper und/oder den Glasplattenverbund zumindest partiell abdeckenden Kunststoffdeckschicht.Moreover, by the DE 84 19 690 U1 an electrical switching device with a trough-shaped base part for receiving a base plate has become known. Some of the necessary for the realization of the required functions electrical / electronic components are arranged on the bottom plate, wherein at least one actuating member is provided as a user interface for influencing the function.

Diese Aufgabe wird durch die im Hauptanspruch angegebenen Merkmale gelöst. Bei einem solchermaßen ausgebildeten Schaltgerät ist besonders vorteilhaft, dass sich das Betätigungsorgan bei mehrteiligem Aufbau auf einfache Art und Weise mittels eines einzigen Werkzeuges herstellen lässt.This object is achieved by the features specified in the main claim.

Des Weiteren ist besonders vorteilhaft, wenn als Kunststoffdeckschicht Polyurethan (PUR) Verwendung findet, dass, ohne besondere Maßnahmen ergreifen zu müssen, eine besonders kratzfeste, selbstheilende sowie eine Tiefenwirkung aufweisende Oberfläche entsteht und dass sich Symbole und Beleuchtungsfenster auf besonders einfache Art und Weise z. B. durch Freilasern am ansonsten fertigen Betätigungsorgan realisieren lassen. Ein solches elektrisches Schaltgerät besteht damit aus besonders wenigen, in mehreren Varianten modifizierbare Modulkomponenten.Furthermore, it is particularly advantageous if the plastic cover layer polyurethane (PUR) is used that, without having to take special measures, a particularly scratch-resistant, self-healing and having a depth effect surface is formed and that symbols and lighting windows in a particularly simple manner z. B. can be realized by free fibers on otherwise finished actuator. Such an electrical switching device thus consists of very few, modifiable in several variants module components.

Wie aus den Figuren hervorgeht, besteht ein solches elektrisches Schaltgerät hauptsächlich aus einem wannenförmig ausgebildeten Sockelteil 1 zur Aufnahme einer elektrischen Leiterplatte 2, auf welcher die zur Realisierung der geforderten Funktionen notwendigen elektrischen/elektronischen Bauelemente 3a, 3b angeordnet sind und welches zur Funktionsbeeinflussung als Benutzerschnittstelle ein Betätigungsorgan 4 aufweist. Das Betätigungsorgan 4 besteht aus einem den Innenraum des Sockelteiles 1 oberseitig verschließenden Grundkörper 5, einem auf der dem Sockelteil 1 abgewandten Hauptfläche angeordneten, aus mehreren Schichten bestehenden Folienverbund 6 und einer den Folienverbund 6 abdeckenden, aus Plyurethan bestehenden Kunststoffdeckschicht 7. Auch der Grundkörper 5 wird an seinem Randbereich 5a partiell von der Kunststoffdeckschicht 7 umschlossen. Außerdem sind zwei Laschen 7a durch die Kunststoffdeckschicht 7 ausgebildet, die jeweils den Randbereich 5a des Grundkörpers 5 überdecken. Mehrere erste Bauelemente sind als kapazitiv arbeitende Schaltelemente 3a und mehrere zweite Bauelemente sind als für die Funktionsanzeige und/oder die Betriebsanzeige vorgesehene Leuchtdioden 3b ausgeführt. Im vorliegenden Fall übernimmt lediglich die eine zentral angeordnete Leuchtdiode 3b die Betriebsanzeige, wohingegen die vierzehn dem Randbereich des Betätigungsorgans 4 zugeordneten Leuchtdioden 3b die Funktionsanzeige übernehmen.As can be seen from the figures, such an electrical switching device mainly consists of a trough-shaped base part 1 for receiving an electrical circuit board 2, on which the required for the realization of the required functions electrical / electronic components 3a, 3b are arranged and which function as a user interface Actuator 4 has. The actuating member 4 consists of a the upper side of the interior of the base part 1 closing body 5, arranged on the base part facing away from the main surface 1, of a plurality Layers existing composite film 6 and the film composite 6 covering, consisting of Plyurethan plastic top layer 7. The main body 5 is partially enclosed at its edge region 5a of the plastic top layer 7. In addition, two tabs 7a are formed by the plastic cover layer 7, each covering the edge region 5a of the main body 5. Several first components are designed as capacitively operating switching elements 3a and a plurality of second components are designed as provided for the function display and / or the operation indicator LEDs 3b. In the present case, only one centrally arranged light-emitting diode 3b takes over the operating display, whereas the fourteen light-emitting diodes 3b associated with the edge region of the actuating element 4 assume the function display.

Wie insbesondere aus Figur 1 und Figur 2 hervorgeht, besteht das elektrische Schaltgerät lediglich aus drei Modulkomponenten, nämlich dem Sockelteil 1, der Leiterplatte 2 und dem in einem einzigen Werkzeug hergestellten Betätigungsorgan 4. Um auf besonders einfache Art und Weise eine Vielzahl an Varianten eines solchen elektrischen Schaltgerätes realisieren zu können, lassen sich sowohl das Sockelteil 1 als auch die Leiterplatte 2 und das Betätigungsorgan 4 bei Bedarf leicht variieren. Das Sockelteil 1 kann z. B. bereits einstückig mit Funktionskomponenten versehen sein, die nicht in jedem Fall benötigt werden. Außerdem kann ein derartiges Sockelteil 1 leicht in mehreren verschiedenen Varianten mit unterschiedlichen geometrischen Abmessungen hergestellt werden, um verschiedene Funktionsanforderungen zu erfüllen. Die Leiterplatte 2 kann z. B. leicht in unterschiedlichen Bestückungsvarianten zur Verfügung gestellt werden, um unterschiedlichen Funktionsanforderungen gerecht zu werden. Das Betätigungsorgan 4 kann in verschiedenen Ausführungen hinsichtlich der Anzahl und Ausgestaltung von Symbolen 6a und Fenstern 6b, 6c an unterschiedliche Funktionsanforderungen angepasst werden. Wie insbesondere aus Figur 1 hervorgeht, weist der Folienverbund 6 ein mittig angeordnetes erstes Fenster 6b auf, welches für die Betriebsanzeige mittels der mittig angeordneten Leuchtdiode 3b vorgesehen ist. Außerdem sind mehrere zweite Fenster 6c vorgesehen, die für eine Funktionsanzeige mittels der im Randbereich angeordneten Leuchtdioden 3b vorgesehen sind. Zu diesem Zweck weist der Grundkörper 5 an entsprechenden Stellen Durchbrüche 5b auf und ist die Kunststoffdeckschicht 7 klar transparent ausgeführt. Zudem besteht die Möglichkeit, zum Beispiel Ausführungen zur Verfügung zu stellen, bei denen das Betätigungsorgan 4 bzw. die Betätigungsorgane 4 starr mit dem Sockelteil 1 verbunden oder aber beweglich am Sockelteil 1 gelagert sind. Beim vorliegenden Ausführungsbeispiel ist das Betätigungsorgan starr mit dem Sockelteil 1 verbunden. Die auf der elektrischen Leiterplatte 2 vorhandenen Schaltelemente 3a sind beim vorliegenden Ausführungsbeispiel als kapazitiv arbeitende Schaltelemente 3a ausgeführt. Die Symbole 6a können hinterleuchtet werden.As in particular from FIG. 1 and FIG. 2 shows, the electrical switching device consists only of three module components, namely the base part 1, the circuit board 2 and the actuator 4 produced in a single tool to be able to realize a variety of variants of such electrical switching device in a particularly simple manner, can be both the base part 1 and the circuit board 2 and the actuator 4 vary slightly if necessary.

Es ist somit ein elektrisches Schaltgerät realisiert, dessen Betätigungsorgan bei mehrteiligem Aufbau auf einfache Art und Weise mittels eines einzigen Werkzeuges hergestellt werden kann. Weiterhin ist bei einem derartigen elektrischen Schaltgerät vorteilhaft, das als Kunststoffdeckschicht Polyurethan (PUR) Verwendung findet, so dass, ohne besondere Maßnahmen ergreifen zu müssen, eine besonders kratzfeste, selbstheilende sowie eine Tiefenwirkung aufweisende Oberfläche entsteht. Symbole 6a und Fenster 6b, 6c lassen sich auf besonders einfache Art und Weise durch Freilasern am ansonsten fertigen Betätigungsorgan 4 realisieren.About a plug 8 and retaining spring 9, the electrical switching device can be easily associated with conventional Busankopplern the building system technology.
