Description
In einem Ausführungsbeipiel wirkt die Taste 3 auf eine von der Taste 3 getrennte Gummimembran, die ihrcrscits eine Kontaktfläche beinhaltet. Vorteilhafterweise ist direkt an der Unterseite der Taste 3 eine Kontaktfläche angeordnet, die beim lierunterdrücken der Taste 3 die Schalterfunktion ausübt. Eine derartigc Anordnung ist in den Fig. 2 bis 4 dargestellt. In one embodiment, key 3 acts one from the button 3 separate rubber membrane, which includes itscrscits a contact surface. A contact surface is advantageously arranged directly on the underside of the button 3, which performs the switch function when pressing button 3. Such a c Arrangement is shown in Figs.
In Fig. 2 ist die Taste 3 an ihrer Unterseite mit der Kontaktfläche 9 aus Kontaktkautschuk versehen, die zusammen mit den beiden Kontaktflächen 10 und 11 den beim Drücken der Taste geschlossenen Schalter bildet. Die Aufhängung der Taste 3 erfolgt wie in Fig. 1. In Fig. 2, the button 3 is on its underside with the contact surface 9 made of contact rubber, which together with the two contact surfaces 10 and 11 forms the switch that is closed when the button is pressed. The suspension of the Button 3 takes place as in Fig. 1.
In Fig. 3 ist an der Unterseite der Taste 3 in die Taste 3 eine Metallkontaktbrücke 15 eingepreßt, die wiederum zusammen mit den Kontaktflächen 10, 11 den beim Drücken der Taste 3 geschlossenen Schalter bildet. In Fig. 3, a metal contact bridge is on the underside of the button 3 in the button 3 15 pressed in, which in turn, together with the contact surfaces 10, 11 when pressing the button 3 forms closed switch.
In Fig. 4 hat die Taste 3 an ihrer Unterseite die Kontur einer Kontaktbrücke und ist mit einer Metallisierung 13 versehen, die wiederum zusammen mit den Kontaktflächen 10, 11 den beim Drücken der Taste geschlossenen Schalter bildet. Die Möglichkeit, daß die Taste 3 selbst an ihrer Unterseite Kontaktflächen bildet, ergibt sich dadurch, daß durch die Lagerung der Taste 3 diese bei ihrer Betätigung eine gleichmäßige Bewegung ohne ein Kippen oder Verkanten ausführt. In Fig. 4, the button 3 has the contour of a contact bridge on its underside and is provided with a metallization 13, which in turn together with the contact surfaces 10, 11 forms the switch that is closed when the button is pressed. The possibility, that the button 3 itself forms contact surfaces on its underside, results from that by the storage of the button 3 this is a uniform when you press it Moves without tilting or tilting.
