Description

brächen versehen sind, werden die Führungsstößel 7, denen jeweils eine Kontaktbrücke 5 mit zugehöriger Druckfeder 6 zugeordnet sind, geführt. Zwischen den beiden Führungsscheiben 8 liegt das Steuerelement 9, an dessen beide Stirnseiten durch Druckfedern 6 Führungsstößel 7 über die zugehörige Kontaktbrücke 5 angedrückt werden. Das Steuerelement 9, das in dem Ausführungsbeispiel als Scheibe ausgebildet und auf die Schalterachse 10 fest aufgepreßt ist, ist auf den beiden Stirnseiten mit Nocken versehen. Diese wirken auf die an ihnen anliegenden Führungsstößel ein und veranlassen bei Drehung des Schalters das doppelpolige öffnen oder Schließen der Schalterkontakte im Sinne des vorgeschriebenen Schaltablaufes durch Bewegen der Kontaktbrücken 5. Broken areas are provided, the guide tappets 7, each of which has a contact bridge 5 with associated Compression spring 6 are assigned, out. The control element 9 is located between the two guide disks 8, on its two end faces by compression springs 6 guide tappets 7 via the associated contact bridge 5 be pressed. The control element 9, which is designed as a disc in the embodiment and on the switch shaft 10 is firmly pressed on, is provided with cams on the two end faces. These work on the guide plunger resting on them and cause the double-pole when the switch is turned open or close the switch contacts in accordance with the prescribed switching sequence by moving the contact bridges 5.

Die Vorteile der Erfindung sind vor allem darin zu sehen, daß bei kleinsten Schalterabmessungen die doppelte Anzahl von Stromwegen vorgesehen werden kann. Dabei ist es gleichgültig, ob die einzelnen Kontaktbrücken als Ruhe-, Arbeits- oder Umschaltekontaktanordnung ausgebildet werden. Vorteilhaft ist außerdem noch, daß für heide Schalterhälften die gleichen Konstruktionelemente verwendet werden können.The advantages of the invention are mainly to be seen in the fact that with the smallest switch dimensions twice the number of current paths can be provided. It does not matter whether the individual contact bridges be designed as a break, make or changeover contact arrangement. Is beneficial In addition, the same structural elements are used for both halves of the switch can.

In der Zeichnung ist der Erfindungsgedanke vorwiegend auf Kontaktbrücken bezogen. Er kann aber auch bei Kotitakthebelanordnungen an sich bekannter Art Anwendung finden.In the drawing, the concept of the invention is primarily related to contact bridges. But he can can also be used in contact lever arrangements of a type known per se.

Claims

The patent 1,051,938 relates to an electrical cam switch with contact bridges, which with corresponding Counter contacts interact. The contact bridges are operated by guide tappets, which reach through the contact bridges and are positively connected to them. When rotating On the switch axis, the switch cams run onto the guide tappets and move them against spring pressure in the direction of the switch axis.

In this proposed in the main patent to design the number of contact bridges are limits when the dimensions of the switch to be very small. May z. If, for example, for reasons of installation, the distance between the mounting holes of the switch base does not exceed 40 mm, then more than four contact bridges or switching paths can not be provided with a normal switch design. Often, however, as is the case with modern 7-step switches, more than four switching paths are necessary.

According to the invention, this object is achieved in that a double-acting control element is provided that affects the guide tappet and the z. B. from a firmly seated on the axis Disc can exist, which is provided with cams on both faces.

In a further embodiment of the invention, two switch bases that provide the necessary Switch contacts, switch bridges, guide tappets and the like. Wear, are joined together in such a way that they each other are facing and the double-acting control element for the guide tappet between them lock in. The control element is located in the middle and controls with its two faces at the same time the guide tappets or contact bridges assigned to them. For this execution Base parts of the same basic construction can be used, as well as the other parts (Contacts, etc.) can be designed in the same way.

One possible embodiment of the concept of the invention in the form of a double socket switch is shown in FIG Drawing showing the cross section of a rotary switch according to the invention as it is, for. B. with advantage can be used as a 7-step heating control switch. Not required for the explanation of the invention Switch parts such. B. the rest mechanism are omitted in the figure.

The two bases 1, to which the stationary contacts 3 are screwed tight with their connecting screws 4 by means of the screws 2, are mutually screwed or riveted together. By means of the discs 8, which are connected to the corresponding through-electric cam switch
with contact bridges
