Description
Die Erfindung betrifft einen elektrischen Kleinstdrehschalter mit auf einem ruhenden ringförmigen Isolierstoffträger angeordneten festen Kontakten und mit auf einem dazu konzentrisch drehbaren Läufer sitzenden, auf ihm radial verschiebbaren Kontakten. Die hierbei als Isolierstoifträger bisher meist gebräuchlichen gestanzten oder gegossenen flachen Kreisringe aus plastischem oder keramischem Werkstoff tragen an ihrem Umfang die ruhenden Kontakte, auf denen der um die Ringachse drehbare Läufer aus Isolierstoff mit dem oder den beweglichen Kontakten gleitet und dadurch die jeweils gewünschten Stromkreise schließt.The invention relates to an electrical miniature rotary switch with fixed contacts arranged on a stationary ring-shaped insulating support and with contacts that are seated on a rotor that can be rotated concentrically and can be moved radially on it. The punched or cast flat ones that have been mostly used as insulating material carriers up to now Circular rings made of plastic or ceramic material carry the static contacts on their circumference, on which the rotor made of insulating material, rotatable around the ring axis, with the movable one or more Contacts and thereby closes the desired circuits.
Erfindungsgemäß gelingt es, die Abmessungen eines die ruhenden Kontakte auf einem ringförmigen Isolierstoifträger und die beweglichen Kontakte auf einem drehbaren Isolierstoffläufer aufweisenden elektrischen Kleinstdrehschalter der eingangs definierten Art dadurch weitgehend gegenüber den bekannten Ausführungen dieser Drehschalterart unter gleichzeitiger Erfüllung der aus der Subminiaturisierung sich hinsichtlich Einfachheit des Zusammenbaues, dauernd zuverlässiger Kontaktgebung, Stoßunempfindlichkeit und Staubzutrittsverhinderung ergebenden Forderungen sowie auch ohne Verringerung der Zahl der Umschaltmöglichkeiten zu verkleinern, daß zur Erzielung des notwendigen Berührungsdruckes unmittelbar zwischen der umlaufenden Außenfläche des Läufers und der jeweiligen Innenfläche der beweglichen Kontakte ein aus elastischem Isolierstoff gefertigter Ring vorgesehen ist, der die beweglichen Kontakte in den einzelnen Schaltstellungen federnd radial gegen die festen Kontakte drückt.According to the invention it is possible to measure the dimensions of a stationary contact on an annular one Isolierstoifträger and the movable contacts on a rotatable insulating rotor having electrical Miniature rotary switches of the type defined at the outset are largely compared to the known ones Executions of this type of rotary switch with simultaneous fulfillment of the sub-miniaturization in terms of simplicity of assembly, permanent reliable contact, insensitivity to impact and dust ingress prevention requirements as well as without reducing the To reduce the number of switching possibilities that to achieve the necessary contact pressure directly between the circumferential outer surface of the rotor and the respective inner surface of the movable one Contacts a ring made of elastic insulating material is provided, which the movable Resiliently presses contacts radially against the fixed contacts in the individual switching positions.
Es ist zwar bereits in der Starkstromtechnik ein feststehendes Schaltstück bekannt, dessen fingerartiger beweglicher Kontakt in eine elastisch ausweitbare, als fester Kontakt dienende zylindrische Aussparung eintreten kann, die aus einer gewissen Anzahl von Keilen zylindrischen Querschnitts gebildet ist, welche gewöhnlich durch elastische Ringe zusammengehalten werden. Diese beweglichen zylindrischen Abschnitte werden daher radial durch diese elastischen Ringe belastet, welche nach Art einer Feder unter Spannung arbeiten. Dem hier vorgeschlagenen Kleinstdrehschalter gegenüber dient der verwendete Ring als elastisches Kissen, das dazu bestimmt ist, als bewegliche Kontakte dienende Metallreiter, deren Anzahl entsprechend den Notwendigkeiten der Schaltung völlig beliebig sein kann, von einer umlaufenden Nut aus nach außen zu belasten.A fixed contact is already known in heavy current engineering, its finger-like movable contact enter an elastically expandable, serving as a fixed contact cylindrical recess can, which is formed from a certain number of wedges of cylindrical cross-section, which usually held together by elastic rings. These movable cylindrical sections are therefore loaded radially by these elastic rings, which are under tension in the manner of a spring work. Opposite the miniature rotary switch proposed here is the ring used as an elastic cushion, which is intended to serve as movable contacts metal tabs, their Number can be entirely any according to the needs of the circuit, from a circulating one Groove from straining to the outside.
Der Läufer des hier vorgeschlagenen Kleinstdrehschalters kann erfindungsgemäß eine senkrecht zuAccording to the invention, the rotor of the miniature rotary switch proposed here can be perpendicular to

Die beweglichen Kontakte des Kleinstdrehschalters nach der Erfindung können vorzugsweise jeweils aus einem U-förmigen Metallbügel bestehen, dessen beide seitliche Schenkel in den betreffenden radialen Führungsaussparungen des Läufers verschiebbar sind und dessen mittlerer Steg sich auf dem elastischen Ring abstützt. Schließlich besteht zweckmäßig der elastische Ring aus einem Kunststoff, vorzugsweise einem Siliconkautschuk.the axis of which has a circumferential groove with two jaws on both sides, in which radial recesses are provided for guiding the movable contacts, the elastic ring on the bottom of the seated bearing formed by the groove and jaws. The moving contacts of the miniature rotary switch according to the invention can preferably each consist of a U-shaped metal bracket, both of which lateral legs are displaceable in the relevant radial guide recesses of the rotor and the middle web is supported on the elastic ring. Finally, there is expediently the elastic ring made of a plastic, preferably a silicone rubber.
