Abstract

Beim einem Verfahren zum Herstellen von Folienschal­ tern (23) werden alle Leiterbahnen (17, 19, 21) nebeneinan­ der auf einer Seite eines einzigen Folienstreifens (15) aufge­ bracht und dieser anschließend so verformt, daß ein Hohl­ raum (29) entsteht, welcher an seiner Innenseite in festgeleg­ ten Schaltabständen die Leiterbahnen (17, 19, 21) trägt. Wird der Folienstreifen (15) vor dem Verbinden mit seitlichen Ausklinkungen (33; 39, 41) versehen, dann wird ein beson­ ders flexibler Folienschalter (31) zur Befestigung auf ge­ krümmten Unterlagen gebildet bzw. die Voraussetzung zur Erzeugung von Einzelschaltern (37) geschaffen. In a process for making a film scarf tern (23) all conductor tracks (17, 19, 21) next to each other on one side of a single film strip (15) brings and this is then deformed so that a hollow space (29) is created, which is fixed on the inside th switching distances the conductor tracks (17, 19, 21) carries. Becomes the film strip (15) before connecting to the side Notches (33; 39, 41), then a special ders flexible membrane switch (31) for attachment to ge curved documents or the prerequisite for Generation of individual switches (37) created.
