Abstract

Rechteckförmiger Kontaktträger (1) für Tastaturen mit den einzelnen Tasten zugeordneten, aus einander gegenüberliegenden Kontaktbahnen (3, 4) aufgebauten Kontaktfeldern (2). Rectangular contact carrier (1) for keyboards with the assigned to individual keys, from opposite one another Contact tracks (3, 4) built contact fields (2).

Die die Kontaktstellen bildenden Kontaktbahnen (3, 4) sollen so gestaltet werden, daß bei der Herstellung des Kontaktträgers (1) im Siebdruckverfahren auch bei Auftreten von Fertigungstoleranzen die Ausschußrate gering gehalten wird. The contact tracks (3, 4) forming the contact points should be designed so that in the manufacture of the Contact carrier (1) in the screen printing process even if it occurs the scrap rate is kept low by manufacturing tolerances becomes.

Dies wird dadurch erreicht, daß - bezogen auf einen Randbereich des Kontaktträgers (1) die Kontaktbahnen (3, 4) im Kontaktbereich parallel und unter einem Winkel von 45° zueinander angeordnet sind. Dadurch wird der Abstand der Kontaktbahnen (3, 4) im Kontaktbereich erheblich vergrößert, ohne daß die Abmessungen des Kontaktfeldes (2) geändert werden. This is achieved in that - in relation to an edge area the contact carrier (1) the contact tracks (3, 4) in the contact area parallel and at an angle of 45 ° are arranged to each other. This will distance the Contact tracks (3, 4) considerably enlarged in the contact area, without the dimensions of the contact field (2) changed will.
