Description
Die Erfindung betrifft eine Drucktaste mit einer größeren Breite, insbesondere eine Leertaste für alpha-numerische Tastaturen, bei der Folien mit aufgedruckten Kontakten vorhanden sind und eine Folie mit einer domförmigen Erhebung ausgestattet ist und beim Niederdrücken über die Taste dieser Foliendom in Kontaktberührung mit der darunterliegenden Folie gelangt.The invention relates to a push button with a larger width, especially a space bar for alpha-numeric keyboards, at of the foils with printed contacts are present and one foil is equipped with a dome-shaped elevation and when depressed via the button of this foil dome in contact with the one below Foil arrives.
Bei bekannten Druckschaltern mit einem Dom (DE-OS 23 41 521), der bei Betätigung der Taste niedergedrückt wird und nach Überwindung eines Druckpunktes Kontakt mit darunterliegenden Kontakten gibt, sind Tasten geringer Breite vorhanden.In known pressure switches with a dome (DE-OS 23 41 521), the when the button is pressed and after overcoming a pressure point there are contact with underlying contacts Small width keys available.
Bei Tasten großer Breite, beispielsweise einer Leertaste für alpha-numerische Tastaturen, reicht ein Dom für eine sichere Betätigung nicht aus. Es ist versucht worden, mehrere derartige Foliendome unterhalb der Taste anzuordnen. Hierdurch wird jedoch die Schaltkraft erhöht. Sie unterscheidet sich von der der übrigen Tasten, wodurch die Bedienung erschwert und fehlerhaft wird und die Taste sich durchbiegen kann.For keys with a large width, for example a space key for alpha-numeric Keyboards, a dome is not enough for safe operation out. Attempts have been made to place several such film domes below the Button. However, this increases the switching force. It makes a difference differs from that of the other keys, making operation more difficult and becomes faulty and the button can bend.
Aufgabe der Erfindung ist es, bei Drucktasten der eingangs genannten Art zu erreichen, daß diese Tasten mit größerer Breite ebenso kontaktsicher und den gleichen Druckpunkt aufweisen wie Tasten normaler Größe.The object of the invention is to push buttons of the aforementioned Way to achieve that these keys with greater width just as reliable and have the same pressure point as normal size keys.
Erfindungsgemäß wird dies dadurch erreicht, daß unterhalb der Taste ein als Foliendom ausgebildeter Kontakt und mindestens ein flach ausgebildeter Hilfskontakt angeordnet sind.According to the invention this is achieved in that below the key as a foil dome trained contact and at least one flat trained auxiliary contact are arranged.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, daß unter der Mitte der Taste ein Foliendom mit darunterliegendem Folienkontakt angeordnet ist und in der Nähe beider Enden der Taste unter dieser je ein flach ausgebildeter Hilfskontakt angebracht ist.An advantageous embodiment of the invention provides that under the middle the button is arranged a foil dome with underlying foil contact and near both ends of the button below this one a flat one Auxiliary contact is attached.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden nachfolgend näher beschrieben. Es zeigen:Embodiments of the invention are shown in the drawing and are described in more detail below. Show it:
Fig. 1 ein Druckschalter mit breiter Taste in der Ansicht von vorn, Fig. 1 a pressure switch with wide key in front view,
Fig. 2 ein Druckschalter in der Seitenansicht im Schnitt. Fig. 2 is a pressure switch in side view in section.
Der in Fig. 1 dargestellte Druckschalter trägt an einem nicht dargestellten Rahmen eine untere Folie 1 mit aufgedruckten Kontakten 4, eine obere Folie 2 mit aufgedruckten Kontakten 5 und 6 und dazwischen eine isolierende Folie 3 mit Öffnungen an den Kontaktstellen. Der Kontakt 6 ist als Foliendom ausgebildet und legt sich während des Herunterdrückens nach Überwindung eines Druckpunktes sprungartig an den darunterliegenden Kontakt 4 an.The pressure switch shown in Fig. 1 carries on a frame, not shown, a lower film 1 with printed contacts 4, an upper film 2 with printed contacts 5 and 6 and in between an insulating film 3 with openings at the contact points. The contact 6 is designed as a film dome and abuts the contact 4 underneath during the pressing down after overcoming a pressure point.
In der Abdeckung 8 oder dem Gehäuse ist die Taste 7 größerer Breite frei gelagert. Sie trägt auf ihrer Unterseite Betätigungsnasen 9, die für die Hilfskontakt 5 etwas größer sind als die Betätigungsnase 10 für den Foliendom 6.In the cover 8 or the housing, the button 7 of greater width is freely stored. It carries on its underside actuating lugs 9 which are somewhat larger for the auxiliary contact 5 than the actuating lug 10 for the film dome 6 .
Durch diese Ausbildung des Druckschalters mit einem Foliendom 6 und Hilfskontakten 5 wird erreicht, daß bei einem Drücken in der Mitte der breiten Taste oder auch außermittig, durch den Hauptkontakt 6 und mindestens einen der Hilfskontakte 5 sicher eine Kontaktgabe mit den Kontakten 4 erfolgt. Dabei erfolgt die Betätigung ebenso leicht und mit derselben Druckpunktcharakteristik wie bei den normalen Tasten, welche nur den Foliendom 6 aufweisen.This design of the pressure switch with a foil dome 6 and auxiliary contacts 5 ensures that when pressing in the middle of the wide button or off-center, the main contact 6 and at least one of the auxiliary contacts 5 ensure contact with the contacts 4 . The operation is just as easy and with the same pressure point characteristic as with the normal keys, which only have the membrane dome 6 .
In Fig. 2 sind die Tasten einer Tastatur noch ausführlicher dargestellt. Diese entsprechen der Fig. 1 bis auf die Ausnahme, daß hier normale Tasten 11 und auch die Taste 7 größere Breite mit einem Folienschanier 13 mit einem Rahmen 12 verbunden ist. Die Betätigungsnasen 9 bzw. 10 an den Tasten sind hier abgeschrägt, da diese bei der Betätigung um das Schanier 13 schwenken.In FIG. 2, the keyboard keys are shown in more detail. These correspond to FIG. 1 with the exception that normal keys 11 and also key 7 of greater width are connected to a frame hinge 13 with a frame 12 . The actuating lugs 9 and 10 on the keys are chamfered here, since they pivot about the hinge 13 when actuated.
