Description

Die, Erfindung besteht in einer als Schaltwalzenkontakt ausgebildeten Kontaktbrücke für elektrische Drehschalter, die mittels Stift und Büchse, welche die Schaltwalze durchdringen und passend ineinandergredfen., kerbstiftartig miteinander verbunden sind, so, daß sie hierdurch auf der Schaltwalze festgehalten werden und elektrisch leitend miteinander verbunden sind. Die Abbildung zeigt eine Schaltwalze mit den. Kontakten der erfindungsgemäßen. Art.The invention consists in one designed as a shift drum contact Contact bridge for electrical rotary switches, which by means of pin and socket, which penetrate the shift drum and fit into each other., like a grooved pin are connected so that they are thereby held on the shift drum and are electrically connected to each other. The illustration shows a shift drum with the. Contacts of the invention. Art.

Die auf der Schaltwalze I, die als Träger der Verbindungskontakte, dient, zu befestigenden Kontakte :2 und 3 durchdringen mit ihren. Fortsätzen 4 und 5,die Schaltwalze; wobei der Fortsatz 4 des Kontaktes 2 als Büchse ausgebildet ist und der Fortsatz 5 einen Stift 6 trägt, welcher in die Büchse des Fo:rtsatzes 4 eingreift. Dieser Stift 6 ist als Kerbstift ausgebildet, so daß er beim Eindrücken in die Büchse des Fortsatzes 4 durch Zurückdrängung des Werkstoffes an den. Lochwandungen der Büchse gehalten wird. Auf diese Weise wird eine innige mechanische und. elektrische Verbindung der beiden Kontaktteile 2 und 3 erreicht.The ones on the shift drum I, which are used as carriers of the connecting contacts, serves to be fastened contacts: 2 and 3 penetrate with their. Appendices 4 and 5, the shift drum; wherein the extension 4 of the contact 2 is designed as a sleeve and the extension 5 carries a pin 6 which is inserted into the sleeve of the extension 4 intervenes. This pin 6 is designed as a grooved pin, so that when pressed in in the sleeve of the extension 4 by pushing back the material to the. Perforated walls the rifle is held. In this way it becomes an intimate mechanical and. electrical Connection of the two contact parts 2 and 3 achieved.

Abgesehen von der zuverlässigen Befestigung bzw. Verbindung der beiden Kontaktteile 2 und 3 entstehen in den ILontalttfiäch-en der Kontaktteile keine Unebenheiten, die eine übermäßige Funkenbildung hervorrufen und zu einem vorzeitigen Verschleiß führen. Bei der sonst üblichen Verbindung von auf zwei verschiedenen Seiten eines Isolierkörpers liegenden Kontaktteilen ist es insbesondere bei Massenfabrikation infolge der Verschiedenheit der Isolierstoffe nicht immer möglich, die Einzelteile so genau herzustellen, daß dien verbindenden Mittel immer um den notwendigen kleinen Betrag länger sind, als das Isolierteil selbst dick ist.Apart from the reliable attachment or connection of the two Contact parts 2 and 3 do not create any unevenness in the contact surfaces, causing excessive sparking and premature wear to lead. With the usual connection of one on two different sides Insulating body lying contact parts, it is especially in mass production Due to the diversity of the insulating materials, the individual parts are not always possible so precisely to produce that the connecting means always around the necessary small Amount longer than the thickness of the insulating part itself.

Durch die kerbstiftartige Verbindung aber kommt es auf diesen kleinen Betrag gar nicht an, so daß die Kontakte durch diese Einrichtung stets gleichmäßig auf der Schaltwalze aufliegen.Due to the grooved connection, however, it comes down to these small ones Amount not at all, so that the contacts through this facility are always even rest on the shift drum.
