Description

Die bisher bekannten Walzenschalter beruhen auf dem Prinzip, durch eine mit Vorsprangen versehene Schaltwalze eine Reihe von Federn zurückzubiegen und hierdurch zur Berührung mit entsprechenden festen Kontakten zu bringen. Um für derartige Schalter eine verhältnismäßig geringe Baulänge und einen ziemlich starken Kontaktdruck zu erhalten, hat man bereits vorgeschlagen, die An-Ordnung so zu treffen, daß durch die Schaltwalze ein in Richtung der Kontakte liegender Druck ausgeübt wird und die Achse der Schaltwalze mit den Kontakten in der gleichen Ebene liegt. Um bei einer derartigen Ausbildung eines Walzenschalters zu vermeiden, daß der von der Schaltwalze ausgeübte starke Druck die Kontakte ungünstig beeinflußt, wird gemäß der Erfindung ein federndes Zwischenglied, das vorzugsweise durch eine Umbiegung der Kontaktfeder oder ein federnd gelagertes Druckstück gebildet ist, zwischen der Schaitwalze und dem durch diese zu bewegenden Kontakt vorgesehen. Dadurch wird selbst bei Anwendung eines verhältnismäßig kräftigen Kontaktdruckes einer zu raschen Abnutzung der Kontakte vorgebeugt. Gleichzeitig wird der Vorgang der Kontaktgebung selbst in der Weise beeinflußt, daß ein zu unvermitteltes, stoßweises Auftreten des Kon-' taktdruckes verhindert ist.The previously known roller switches are based on the principle of one with protrusions provided shift drum to bend back a number of springs and thereby to contact with corresponding fixed contacts bring to. In order to obtain a relatively short overall length and a fairly strong contact pressure for such switches, it has already been proposed to make the order so that by the shift drum a pressure lying in the direction of the contacts is exerted and the axis of the shift drum with the contacts in the same Level lies. In order to avoid with such a design of a roller switch that the strong pressure exerted by the shift drum adversely affects the contacts, is according to the invention a resilient intermediate member, which is preferably by a bend the contact spring or a resiliently mounted pressure piece is formed between the shift roller and the one to be moved by this Contact provided. As a result, even if a relatively strong contact pressure is applied, one becomes too fast Prevented wear of the contacts. At the same time the process of making contact itself influenced in such a way that a too sudden, intermittent occurrence of the conflict cycle printing is prevented.

Die Zeichnung zeigt in Fig. ι und 2 zwei Ausführungsmöglichkeiten der Erfindung. Gemäß Fig. ι ist -eine Blattfeder 7 auf einem Träger 2 gelagert und an ihrem freien Ende umgebogen. Der Kontakt 3 auf der Blattfeder 7 arbeitet mit dem festen Kontakt 4 zusammen. Auf die Umbiegung der Blattfeder 7 wirkt die Schaltwalze 5 mit dem Stift 6 ein, wodurch die Kontakte 3,4 zur Berührung gebracht werden.The drawing shows in Fig. Ι and 2 two possible embodiments of the invention. According to Fig. Ι a leaf spring 7 is mounted on a carrier 2 and bent at its free end. The contact 3 on the leaf spring 7 works together with the fixed contact 4. On the bending of the leaf spring 7, the shift drum 5 acts with the pin 6, whereby the contacts 3, 4 are brought into contact.

Bei der Anordnung nach Fig. 2 ist an dem Träger 2 außer der Kontaktfeder 7 mit dem Kontakt 3 noch eine weitere Blattfeder 8 unterhalb der Feder 7 befestigt, die ein Druckstück 9 trägt. Dieses wird von der Schaltwalze 5 "mittels -des Stiftes 6 zum Ausschlag gebracht, wodurch weiterhin die Kontaktfeder 7 mit dem Kontakt 4 zur Berührung kommt.In the arrangement according to FIG. 2, in addition to the contact spring 7 with the contact 3, another leaf spring 8 is attached to the carrier 2 below the spring 7 and carries a pressure piece 9. This is brought to deflection by the shift drum 5 ″ by means of the pin 6, whereby the contact spring 7 continues to come into contact with the contact 4.
