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
