  Wasserdichter Schalter. 



   Bei Kippschaltern ist es bekannt, die Austrittsöffnung für das Betätigungsglied durch eine glatte Gummihaube wasserdicht abzuschliessen, innerhalb welcher dann der Kipphebel angeordnet ist. Die Erfindung betrifft eine Verbesserung dieser Anordnung, bestehend in einer ziehharmonihaartigen Ausbildung der Abschlusshaube. Diese Anordnung eignet sich insbesondere für Druckknopfsehalter, bei denen der Druckknopf zwei verschiedene Lagen annehmen kann, wie vornehmlich bei Doppeldruckknopfschaltern, da die ziehharmonikaartig ausgebildete Haube einerseits bei heraustretendem Druckknopf nicht übermässig gedehnt wird und   hiedureh   anderseits selbst nach längerem Gebrauch bei hinein-   gedrücktem   Knopf nicht schlaff herabhängt. 



   Die Erfindung ist in der Zeichnung in Anwendung auf einen Druekknopfschalter mit zwei wechselweise betätigten Druckknöpfen in einigen beispielsweisen Anordnungen dargestellt. 



   Gemäss Fig. 1 sind mit a die Druckknöpfe und mit   b   der   Gehäusedeckel   bzw. die Deckplatte, in welcher die Durchtrittsöffnungen c vorgesehen sind, bezeichnet. Die Hauben d sind   ziehharmonika-   artig gefaltet und mittels ihrer Randwülste f an den konischen Ansätzen e festgehalten. In der abge- änderten Anordnung nach Fig. 2 sind die konischen Ansätze e nach innen gerichtet und die Hauben durch die   Öffnung c gezogen, wodurch   eine besonders zuverlässige Befestigung erzielt wird. Um das Durchwetzen der Haube zu verhüten, ist sie an der Griffstelle (gegebenenfalls auch durch ein fremdes Material) verstärkt. 
 EMI1.1 
 Aussehen des Schalters nicht verzichten will.

   Gemäss Fig. 3 ist die Haube d durch ein   Plättchen   h geschützt, das als   Lauffläche   für den Schwinghebel ausgebildet ist. Die Haube kann aber auch nach Fig. 4 am Umfang des Druckknopfes angeklebt bzw., wenn dieser aus Hartgummi besteht, angeschweiss sein. 



   Als weiterer Vorteil der Erfindung ist noch   anzuführen,   dass man durch die   ziehharmonika-   artige Ausbildung der Haube nicht an deren Herstellung aus Gummi gebunden ist, sondern sie auch aus andern wasserdichten Stoffen herstellen kann, wodurch ihre Haltbarkeit bedeutend erhöht zu werden vermag.

  Waterproof switch.



   In the case of toggle switches, it is known to close off the outlet opening for the actuating element in a watertight manner by means of a smooth rubber hood, within which the toggle lever is then arranged. The invention relates to an improvement of this arrangement, consisting in an accordion-like design of the end cap. This arrangement is particularly suitable for push-button holders in which the push-button can assume two different positions, such as primarily with double-push-button switches, since the accordion-like hood is on the one hand not stretched excessively when the push-button emerges and on the other hand does not become slack even after prolonged use when the button is pushed in hangs down.



   The invention is shown in the drawing in application to a push button switch with two alternately operated push buttons in some exemplary arrangements.



   According to FIG. 1, the pushbuttons are designated with a and the housing cover or the cover plate in which the passage openings c are provided with b are designated. The hoods d are folded like an accordion and are held on the conical extensions e by means of their edge beads f. In the modified arrangement according to FIG. 2, the conical extensions e are directed inwards and the hoods are drawn through the opening c, whereby a particularly reliable fastening is achieved. In order to prevent the hood from being worn through, it is reinforced at the grip point (possibly also by a foreign material).
 EMI1.1
 Appearance of the switch does not want to do without.

   According to Fig. 3, the hood d is protected by a plate h, which is designed as a running surface for the rocker arm. The hood can also be glued to the circumference of the push button according to FIG. 4 or, if it is made of hard rubber, welded on.



   Another advantage of the invention is that the accordion-like design of the hood does not mean that it is made from rubber, but can also be made from other waterproof materials, which can significantly increase its durability.
