Description

  

  Elektrischer Drehschalter mit durch Nocken gesteuerten Kontaktfedern    Der     Gegenstand    des Hauptpatentes ist, ein       elektrischer    Drehschalter mit durch Nocken  gesteuerten und in Längsrichtung zur     Scha.l-          teraehse    angeordneten     Kontaktfedern.    Um die  Anzahl von     Sehaltmöglichkeiten    erhöhen zu  können, ist der vorliegende Erfindungsgegen  stand dadurch     gekennzeichnet,

      dass ein fest  stehender     Isolierstoffkern    innerhalb der     um     die     Sehaltera.chse    herum angeordneten Kon  taktfedern zur Lagerung der Schalterachse  und als Träger von drei     ortsfesten    Kontakten  vorgesehen ist, die mit. Kontaktfedern zusam  menwirken, welche von drei Nocken     gesteuert     werden, die in drei zur     Schalteraehse    senk  rechten. Ebenen angeordnet sind und von  denen der mittlere über Stifte auf die     Kon-          takt.federn        einwirkt.     



  In der Zeichnung ist ein Ausführungsbei  spiel des     Schalters    in einem Schnitt     darge-          :stellt.     



  Der Sockel 1 besitzt einen inmitten der um  die     Sehalterachse    angeordneten Kontaktfedern       feststehenden        Isolierstoffkern    2, auf dem die  drei Kontaktringe 3, 4 und 5 in drei verschie  denen Ebenen artgeordnet sind. Die Kontakt  federn werden an ihrem     vordern    über die  Kontaktstellen hinausragenden Ende durch  die Steuernocken 6, 7 und 8 von den Kontakt  ringen 3, 4 und. 5 abgehoben und wirken je       paarweise    mit einem     Kontaktring        zusammen.     Der mittlere Steuernocken 7 ist mit dem einen.    äussern Steuernocken 6 zu     einem    einzigen Kör  per 9 vereinigt.

   Dieser Körper     besitzt    auch die  in axialer Richtung vorstehenden Sperrasten  nocken 7.0, welche in entsprechende Kasten  nocken des zentralen     Isolierstoffkernes    ein  greifen. Der Körper 9, welcher mit der     im          Kern    2 gelagerten Schalterachse 11,     unver-          drehbar    verbunden ist., befindet sich in einer  zentralen     Ausnehmung    12 des     Isolierstoffker-          nes        '?.     



  Bei dem     dargestellten        Ausführungsbeispiel     ist der     Körper    9 von unten in die     Ausneh-          mung    12 eingesetzt.  



  Es ist einerlei, ob die zentrale     Ausneh-          mung    1.2 nach unten oder nach oben offen     ist,.     Indem letzteren Falle sind die einzelnen Teile  in entsprechend     umgekehrter    Reihe in dem  Schalter angeordnet.  



  Durch die in dem Körper 9     vorhandene     Feder 13 werden die Rasten 10 in die Gegen  rasten des     Isolierstoffkernes    2 eingedrückt.  Die     Ablenkung    der Kontaktfeder 14     erfolgt     durch den Nocken 7 über einen Bolzen oder  Stift. 15.



  Electric rotary switch with contact springs controlled by cams The subject of the main patent is an electric rotary switch with contact springs controlled by cams and arranged in the longitudinal direction to the switch axis. In order to be able to increase the number of viewing possibilities, the present subject matter of the invention is characterized in

      that a stationary insulating material core is provided within the contact springs arranged around the Sehaltera.chse for mounting the switch axis and as a carrier for three stationary contacts, which with. Contact springs work together, which are controlled by three cams in three perpendicular to the switch axis. Levels are arranged and of which the middle one acts on the contact springs via pins.



  In the drawing, an exemplary embodiment of the switch is shown in a section.



  The base 1 has a fixed insulating material core 2 in the middle of the contact springs arranged around the holder axis, on which the three contact rings 3, 4 and 5 are arranged in three different planes. The contact springs are at their front end protruding beyond the contact points through the control cams 6, 7 and 8 of the contact rings 3, 4 and. 5 lifted and each work in pairs with a contact ring. The middle control cam 7 is with the one. outer control cam 6 combined into a single body by 9.

   This body also has the axially protruding locking catch cam 7.0, which cams in the corresponding box of the central insulating material core. The body 9, which is non-rotatably connected to the switch axis 11 mounted in the core 2, is located in a central recess 12 of the insulating material core.



  In the illustrated embodiment, the body 9 is inserted into the recess 12 from below.



  It does not matter whether the central recess 1.2 is open at the bottom or at the top. In the latter case, the individual parts are arranged in the switch in a correspondingly reversed order.



  Due to the spring 13 present in the body 9, the catches 10 are pressed into the counter-catches of the insulating core 2. The deflection of the contact spring 14 is carried out by the cam 7 via a bolt or pin. 15th
