Description

  • Dreischalter Die Erfindung besteht in einer neuen Kontaktanordnung für Drehschalter. Es werden erfindungsgemäß in, der Schalttrommel als Strombrücken eine öder mehrere Kontaktfedern in nach der Mantelfläahe zu offerwn längsachsigen Kanälen derart angeordnet, daß sie radial federnd mit ihren übereinanderliegenden Kontaktflächen auf den Gegenkontakten schleifen. Weitere erfindungsgemäße Maßnahmen bestehen darin, daß die in der Schalttrommel befindlichen Kanäle innen durch längsachsige Nuten verbreitert sind, damit in diese Verbreiterungen Führungslappen der Kontaktfedern eingeschoben werden können und die Kontaktfedern an beiden Enden U-förmig gegeneinander gebogen sind, so daß diese Enden zur Kontaktgabe an den beiden übereinanderliegenden Sockelkontakten dienen.Three switch The invention consists in a new contact arrangement for rotary switch. According to the invention, the switching drum is used as current bridges one or several contact springs in longitudinal axes to be offered after the jacket surface Channels arranged so that they are radially resilient with their superimposed Grind the contact surfaces on the mating contacts. Further measures according to the invention consist in that the channels located in the switching drum inside by longitudinal axis Grooves are widened so that guide tabs of the contact springs are in this widened area can be inserted and the contact springs at both ends U-shaped against each other are bent so that these ends for making contact with the two superimposed Socket contacts are used.
  • Abb. i der Zeichnung zeigt den Schalter im Längsschnitt, Abb.2 eine Draufsicht auf den Schalter, Abb.3 einen Schnitt durch die Schalttrommel quer zur Achsrichtung, Abb,, 4 eine Ansicht des Sockels von oben und Abb.5 eine Strombrücke in aufgebogenem Zustande.Fig. I of the drawing shows the switch in longitudinal section, Fig.2 a Top view of the switch, Fig.3 a section through the switching drum transversely to the Axial direction, Fig ,, 4 a view of the base from above and Fig.5 a current bridge in an upturned state.
  • Wie aus der Abb@.4 hervorgeht, befinden sich an der Innenwandung des Sockels i Nuten,-, deren Tiefe ungefähr der Stärke der zu den Klemmen 3 und 4 gehörenden Schaltkontakte 5 und 6 entspricht, die in den Nuten 2 mit der Innenwandung des Sockels bündig liegen. Die in der Schalttrommel als Strombrücken angeordneten Kontaktfedern bewegen sich daher ohne Hemmung über die Sockelkontakte und die dazwischenliegenden Isolierwände. Die Nuten 2 .gehen, wie aus Abb: i zu :ersehen, an der inneren Sockelwand von oben bis unten durch. Dieses hat den Zweck, das Pressen des Sockelkörpers zu erleichtern: Ferner besitzt auch die Schalttrommel 16 (Abb. 3) je nach der Art des Schalters mehrere Kanäle 7, welche nach der Mantelfläche zu offen sind. Die Kanäle 7 haben innen. Verbreiterungen 8, in welche die vorspringenden Kanten io der als Strombrükken dienenden Kontaktfedern 9 (Abb. 5) greifen.As can be seen from Fig @ .4, are located on the inner wall of the Base i grooves, - the depth of which is approximately the thickness of that belonging to terminals 3 and 4 Switching contacts 5 and 6 correspond to those in the grooves 2 with the inner wall of the base lie flush. The contact springs arranged as current bridges in the switching drum therefore move without inhibition over the socket contacts and those in between Insulating walls. The grooves 2. Go, as can be seen from Fig: i, on the inner base wall from top to bottom. This has the purpose of pressing the base body facilitate: Furthermore, the switching drum 16 (Fig. 3), depending on the type of Switch several channels 7, which are open to the lateral surface. The channels 7 have inside. Broadenings 8, in which the protruding edges io the as Grab the contact springs 9 (Fig. 5) used for current bridges.
  • Die Kontaktfedern 9 sind, wie aus Abb. i zu ersehen, doppelt U-förmig gebogen und liegen mit ihren freien Enden 17 und i i an den Kontaktflächen 5 und 6 der Klemmen 3 und 4 an. Die Kontaktklemmen 4 sitzen auf besonderen Rippen 12 des Sockels, welche oben dachförmig ausgebildet sind (Abb. i) und haben hierfür an ihren Sitz-Flächen eine gleiche dachförmige Ausbildung. Sie werden nicht durch Schrauben oder Niete am Sockel befestigt, sondern durch besonders eingeführte Stege 1,3 aus Isolierstoff und die Lagerplatte 14 festgehalten. Diese Einrichtungen verein=fachen den Zusammenbau des Schalters.The contact springs 9 are, as can be seen from Fig. I, double U-shaped bent and lie with their free ends 17 and i i on the contact surfaces 5 and 6 of terminals 3 and 4. The contact terminals 4 sit on special ribs 12 of the Base, which are roof-shaped at the top (Fig. I) and have this on their Seat surfaces have the same roof-shaped training. You are not screwed by or rivets attached to the base, but from specially introduced webs 1,3 Insulating material and the bearing plate 14 held in place. Simplify these facilities assembling the switch.
