Abstract

Films having printed contacts are provided for a push button of relatively large width, especially as a space bar for alphanumeric keyboards. A film is equipped with a dome-shaped projection and touching contact is made with the film located underneath when this film dome is pressed down by means of the key. Easy and error-free operation is ensured in that a contact (which is constructed as a film dome) and at least one auxiliary contact (which is constructed to be flat) are arranged underneath the push button.

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 one Width, especially a space bar for alpha-numeric Keyboards, in the case of foils with printed contacts are present and a film with a dome-shaped Elevation is equipped and when depressed over the Button of this foil dome in contact with the underlying one 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), which is depressed when the button is pressed and after Overcoming a pressure point contact with those below Contacts, there are buttons of small width.

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 aber der Druckpunkt stärker, er unterscheidet sich von dem der übrigen Tasten, wodurch die Bedienung erschwert und fehlerhaft wird und die Taste kann sich durchbiegen.For keys with a large width, for example a space key for alpha-numeric keyboards, one dome is enough for one safe actuation not off. It has been tried arrange several such foil domes below the button. This makes the pressure point stronger, it differentiates different from that of the other buttons, which makes the operation becomes difficult and faulty and the button may turn up bend.

Gegenstand der Erfindung ist es, bei einer Drucktaste der eingangs genannten Art zu erreichen, daß die Taste mit einer größeren Breite genauso leicht und fehlerfrei eine Kontaktgabe ermöglicht und zu bedienen ist, wie die übrigen normalen Tasten, insbesondere mit gleichem Druckpunkt. The object of the invention is in a push button to achieve that the key with a larger width just as easily and error-free a contact enabled and operated like the rest normal keys, especially with the same pressure point.  

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 button a contact designed as a foil dome and at least one flat auxiliary contact arranged are.

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 of the button a foil dome with an underlying Foil contact is arranged and close both ends of the button under this one each flat Auxiliary contact is attached.

Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden nachfolgend näher beschrieben. Es zeigen:Embodiments of the invention are in the drawing are shown 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 etwas größer sind für die Hilfskontakte 5 und eine kleinere bzw. zurückversetzte 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 contacts 5 and a smaller or recessed 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 abweichend zu einem Ende durch den Hauptkontakt 6 und mindestens einen der Hilfskontakte 5 sicher eine Kontaktgabe an 4 erfolgt. 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 alternatively to one end through the main contact 6 and at least one of the auxiliary contacts 5, contact is made with 4 .

Dabei erfolgt die Betätigung genauso leicht und mit derselben Druckpunktcharakteristik wie bei vorhandenen normalen Tasten mit einem Foliendom.The operation is just as easy and with same pressure point characteristic as existing ones normal buttons with a foil dome.

In Fig. 2 sind die Tasten einer Tastatur noch ausführlicher dargestellt und diese entsprechen der Fig. 1 bis auf die Ausnahme, daß hier normale Tasten 11 und auch die Taste 7 größerer 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 keys of a keyboard are shown in more detail and these correspond to Fig. 1 with the exception that normal keys 11 and also the key 7 of greater width are connected here with a foil hinge 13 with a frame 12 . The actuating lugs 9 and 10 on the keys are chamfered here because they pivot about the hinge 13 when actuated.
