Abstract

Ein zum Aufbau auf Leiterplatten geeigneter Drucktastenschal­ ter erfährt eine Verbesserung durch eine Verkleinerung des im Gehäuse des Schalters zu dichtenden Raum.
Die erfindungsgemässe Konstruktion erlaubt zudem, leicht aus­ wechselbare Tastenkappen (1) zu verwenden. Eine Erhöhung der Betriebssicherheit des Schalters ist durch die Konstruktion der Kalotte (2) mit einem zentralen Führungskragen (2a), wel­ cher die Buchse (4) radial umschliesst, möglich. Als Material für diese Kalotte (2) haben sich insbesondere Silikonelasto­ mere bewährt.
