Abstract
Description
Die Erfindung betrifft einen mehrstufigen Schalter nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a multi-stage switch the preamble of claim 1.
Derartige Schalter sind bereits als mechanische Schalter bekannt.Such switches are already mechanical switches known.
Folienschalter sind Schalter mit selbsttätigem Rückstell effekt, die mit Hilfe von Schaltfolien realisiert werden und die als Flächenschalter oder Domschalter ausgebildet sind. Die Kontaktgabe erfolgt dabei durch Druck auf eine obere Schaltfolie bzw. einen Schaltdom, infolgedessen ein Kontakt zu einem auf einer unteren Schaltfolie ange brachten Schaltkontakt geschlossen wird, der durch Ab standsfolien oder durch die Ausbildung des Doms vom obe ren Schaltkontakt getrennt ist.Membrane switches are switches with automatic reset effect, which are realized with the help of switching foils and designed as a surface switch or cathedral switch are. The contact is made by pressing on a upper switching foil or a switching dome, as a result a contact to one on a lower switching film brought switch contact is closed by Ab stand foils or through the formation of the cathedral from above ren switch contact is disconnected.
Solche Folienschalter lassen sich als "Schließer" für die Ausführung nur eines bestimmten Schaltvorgangs ein setzen.Such membrane switches can be used as "closers" for the execution of only a certain switching operation put.
Der Erfindung liegt die Aufgabe zugrunde, einen Schalter auf der Grundlage von Folienschaltern anzugeben, mit dem mehrere Funktionen gleichzeitig ausgeführt werden kön nen.The invention has for its object a switch on the basis of membrane switches, with which multiple functions can be performed simultaneously nen.
Dies wird erfindungsgemäß dadurch erreicht, daß der Schalter ein mehrschichtiger Folienschalter ist.This is achieved in that the Switch is a multilayer membrane switch.
Im mehrschichtigen Folienschalter sind dabei mehrere Flächenschalter und/oder Domschalter übereinander lie gend integriert. There are several in the multi-layer membrane switch Surface switch and / or cathedral switch lie one above the other integrated.
Der Erfindung liegt die Erkenntnis zugrunde, daß durch Vorgabe unterschiedlicher Schaltkräfte bei Flächenschal tern bzw. Domschaltern ein mehrstufiger Schaltvorgang ausgelöst werden kann und somit ein mehrstufiger Folien schalter bzw. eine Mehrkontakt-Konfiguration realisier bar ist.The invention is based on the finding that through Specification of different switching forces for surface formwork ters or dome switches a multi-stage switching process can be triggered and thus a multi-stage film switch or a multi-contact configuration is cash.
Die Schaltkräfte können bei Domschaltern durch die Ge staltung des Doms und bei Flächenschaltern durch die Dicke der Abstandsfolie zwischen den beiden Schaltfolien bzw. durch die Größe der Schaltöffnung einstellbar vor gegeben werden.The switching forces can be at dome switches by the Ge design of the cathedral and for area switches by the Thickness of the spacer foil between the two switching foils or adjustable by the size of the switch opening are given.
Mit einem einzigen mehrstufigen Folienschalter lassen sich mehrere getrennte Signale auslösen bzw. mit einer Bewegung können durch Variation des Drucks mehrere Funk tionen ausgeführt werden. Beispielsweise können mehrere Geschwindigkeitsstufen (langsam, schnell) gesteuert wer den oder eine Ansteuerung von gegensätzlichen Funktionen wie laut/leise, hell/dunkel usw. durch Variation des Tastendrucks eines einzigen Schalters, beispielsweise bei einem Fernsehgerät oder Videogerät, vorgenommen wer den.Leave with a single multi-stage membrane switch trigger several separate signals or with one Movement can be multiple radio by varying the pressure operations are carried out. For example, several Speed levels (slow, fast) controlled who the or a control of opposite functions how loud / quiet, light / dark etc. by varying the Pressing a single switch, for example on a television or video device, who made the.
Denkbar ist auch, mit dem ersten Tastendruck den Wert einer bestimmten Größe anzuwählen bzw. einzustellen und mit weiteren Tastendrücken diesen Wert zu fixieren; bei spielsweise kann beim Programmieren ein leichter Tasten druck einen Vorgang auslösen und ein stärkerer Tasten druck das Programmier-Resultat sichern.It is also conceivable to press the value with the first key select or set a certain size and to fix this value with further key presses; at for example, programming can be easier Press to trigger a process and a stronger button save the programming result.
Bei Tasten mit mehreren Funktionen kann ein Funktions wechsel durch Variation des Tastendrucks erreicht wer den; die jeweilige Funktion kann überdies optisch ange zeigt werden.A function can be used for keys with multiple functions change achieved by varying the key press the; the respective function can also optically indicated be shown.
Vorteilhaft wird der mehrschichtige Folienschalter aus einer einzigen Folie hergestellt, nach Aufbringen von Abstandsfolien durch einen Faltvorgang in seine endgül tige Form gebracht und anschließend verklebt. The multilayer membrane switch is advantageous a single film, after applying Spacer foils through a folding process in its endgül brought shape and then glued.
Der Schalter kann somit in einem Stück bearbeitet wer den, beispielsweise kann die Bedruckung der Folie mit Leiterbahnen, Kontaktflächen oder mit einem Designdruck in einem einzigen Arbeitsgang erfolgen.The switch can thus be machined in one piece the, for example, the printing of the film with Conductor tracks, contact areas or with a design print done in a single operation.
Für die mehrstufigen Folienschalter sind alle möglichen Ausführungsformen denkbar, in denen sich Domschalter und Flächenschalter kombinieren lassen; beispielsweise kann ein mehrstufiger Folienschalter aus einem Domschalter und mehreren Flächenschaltern, aber auch aus mehreren Flächenschaltern allein bestehen.All are possible for the multi-stage membrane switches Embodiments conceivable in which cathedral switches and Let the surface switch be combined; for example can a multi-stage membrane switch from a cathedral switch and several surface switches, but also several Surface switches exist alone.
Die Betätigung des Folienschalters kann entweder direkt (manuell) oder indirekt (mit Hilfe von Schaltstößeln) erfolgen.The membrane switch can either be operated directly (manually) or indirectly (with the aid of switching tappets) respectively.
Ungewollte Fehlschaltungen lassen sich vermeiden, wenn die Schaltkräfte der einzelnen Schaltstufen ausreichend unterschiedlich gewählt werden.Unintentional switching errors can be avoided if the switching forces of the individual switching stages are sufficient can be chosen differently.
Die Erfindung und ihre Herstellung sollen nachstehend anhand eines Ausführungsbeispiels beschrieben werden, bei dem ein Flächenschalter und ein Domschalter in einem zweistufigen Folienschalter übereinander liegend inte griert sind.The invention and its manufacture are set out below are described using an exemplary embodiment, where a surface switch and a cathedral switch in one two-stage membrane switch one above the other inte are free.
Die Fig. 1 zeigt den zweistufigen Folienschalter im Schnitt, in der Fig. 2 ist die Schaltfolie beim Falt prozeß dargestellt. Fig. 1 shows the two-stage membrane switch in section, in Fig. 2 the switching film is shown during the folding process.
Als Schaltfolie 3 dient ein Polyesterstreifen mit den Abmessungen von beispielsweise 640×500 mm und einer Dicke von beispielsweise 125 µm. Diejenigen Stellen, an denen Schaltkontakte 5 und Anschlußleitbahnen 6 entspre chend des Layouts vorgesehen sind, werden in einem ein zigen Arbeitsgang mit Leitsilber bedruckt, auf den für die Anschlüsse vorgesehenen Teil der Folie wird eine Schutzfolie aufgebracht, die Schaltfolie in die gewünsch ten Einzelteile ausgeschnitten und die Dome des Domschal ters 2 gebildet. A polyester strip with dimensions of, for example, 640 × 500 mm and a thickness of, for example, 125 μm is used as switching film 3 . Those places at which switching contacts 5 and connecting tracks 6 are provided accordingly to the layout are printed with conductive silver in a single operation, a protective film is applied to the part of the film provided for the connections, the switching film is cut into the desired individual parts and the domes of the Domschal ters 2 formed.
Anschließend werden Abstands- bzw. Distanzfolien 4, die eine Stärke von beispielsweise 70 µm besitzen und beid seitig mit Kleber versehen sind, auf die Schaltfolie 3 aufgebracht. Die gesamte Konfiguration wird nun mittels Vorrichtungen gefaltet, wobei in der Figur nicht darge stellte Metallstifte in Montagehilfsbohrungen sicher stellen, daß die Schaltkontakte 5 übereinander zu liegen kommen. Die Folien werden sodann verklebt und Lötkon takte bzw. Stecker angebracht; eventuell kann noch ein Designdruck auf die Folienrückseite gedruckt oder eine bedruckte Designfolie aufgeklebt werden.Then spacing foils 4 , which have a thickness of, for example, 70 μm and are provided on both sides with adhesive, are applied to the switching foil 3 . The entire configuration is now folded by means of devices, in the figure not shown Darge metal pins in auxiliary mounting holes ensure that the switching contacts 5 come to lie on top of each other. The foils are then glued and Lötkon clock or plug attached; possibly a design print can be printed on the back of the film or a printed design film can be stuck on.
Durch den Schaltdom des Domschalters 2 existiert eine füllbare Barriere zwischen den beiden Schaltstufen des zweistufigen Folienschalters; dabei wird bei einem leich ten Tastendruck auf den Schalter zunächst der Flächen schalter 1 und bei stärkerem Tastendruck der Domschalter 2 betätigt, wobei der Schnappeffekt in der zweiten Schalt stufe (Domschalter 2) den präzisen Schaltvorgang bestä tigt.The switch dome of the dome switch 2 creates a fillable barrier between the two switching stages of the two-stage membrane switch; the light switch 1 is pressed first and then the dome switch 2 is pressed, the snap effect in the second switching stage (dome switch 2 ) confirms the precise switching operation.
In der Fig. 1 ist auch ein Schaltstößel 7 dargestellt, mit dessen Hilfe eine präzise Auslösung des Schaltvor gangs ermöglicht wird.In Fig. 1, a switching plunger 7 is shown, with the help of a precise triggering of the Schaltvor gear is made possible.
