Gegenstand vorliegender Erfindung ist ein Heizkissenschalter für bewegliche Schnurleitungen, bei dem, wie bekannt, die Schaltung mittels eines durch einen Hebel betätigten Schaltrades erfolgt und das flache Gehäuse in der Längsrichtung geteilt ist. In dem Unterteil des Schaltgehäuses sind das Schaltwerk und alle stromführenden Teile angeordnet. The subject of the present invention is a heating pad switch for movable cord lines, in which, as is known, the circuit is carried out by means of a ratchet wheel operated by a lever and the flat housing is divided in the longitudinal direction. The switching mechanism is located in the lower part of the switch housing and all live parts arranged.
ίο Erfindungsgemäß· sind nun der gesamte Schaltmechanismus und die Kontaktteile innerhalb des Gehäuses nochmals durch eine Isolierabdeckung in Gestalt einer Schale oder Platte nach oben geschützt, und über dieser '5 Abdeckung ist der gerade aus Metall bestehende, jedoch isoliert angeordnete Schalthebel angeordnet, der durch einen schmalen Schlitz aus dem Oberteil des Gehäuses seitlich heraustritt. Durch diese besondere Isolationsabdeckung wird erreicht,, daß Fremdkörper, die durch den Schlitz in das Gehäuse eindringen, nicht mit den stromführenden Teilen in Verbindung treten können.ίο According to the invention are now the entire Switching mechanism and the contact parts within the housing again through a Insulating cover in the form of a shell or plate protected upwards, and over this The cover is the switching lever, which is made of metal but is arranged in an isolated manner arranged, which emerges laterally through a narrow slot from the upper part of the housing. This special insulation cover ensures that foreign bodies, that penetrate through the slot into the housing, not with the live parts can contact.
Ein Schalter nach der Erfindung ist in der Zeichnung dargestellt, und zwar zeigtA switch according to the invention is in the Drawing shown, namely shows
Fig. ι den Schalter im Aufriß im Schnitt, Fig. 2 im Grundriß in geöffnetem Zustande, Fig. 3 im Seitenriß im Schnitt.Fig. Ι the switch in elevation in section, Fig. 2 in plan in the open state, Fig. 3 in side elevation in section.
In dem Unterteil des längsgeteilten Gehäuses ist der Schaltmechanismus derart angeordnet, daß die Achse c, auf der das Schaltrad e mit den Kontaktteilen / drehbar gelagert ist, von einem geraden Schalthebel^, der aus der schmalen Öffnung m des Oberteiles des Gehäuses α heraustritt, betätigt wird.In the lower part of the longitudinally divided housing, the switching mechanism is arranged such that the axis c, on which the ratchet wheel e with the contact parts / is rotatably mounted, is actuated by a straight shift lever ^ which emerges from the narrow opening m of the upper part of the housing α will.
Die Kontaktteile/ treten mit den Kontaktfedern g·, die entsprechend den zu schaltenden Stromkreisen in beliebiger Anzahl vorhanden sind, derart in Verbindung, daß sie sich jeweils zwischen zwei Kontaktfedern schleifend bewegen.The contact parts / contact the contact springs g ·, which correspond to the ones to be switched Circuits are available in any number, so in connection that they between two contact springs move dragging.
Die Kontaktfedern g sind, wie bekannt, mit den Anschlußbuchsen /ζ, deren Befestigungsbolzen gleichzeitig im Unterteil b des längs- geteilten Gehäuses eingepreßt werden, fest verbunden.As is known, the contact springs g are firmly connected to the connection sockets / ζ, the fastening bolts of which are simultaneously pressed into the lower part b of the longitudinally divided housing.
Unter dem Schaltrad e ist eine Sperrung ο angeordnet, welche mittels Druckfeder Λ gegen das Schaltrad gedrückt wird; auch ist das Sehaltrad oben zur momentweisen Schaltung mit !einer Vorschnellfeder ρ versehen.Under the ratchet wheel e there is a lock ο which is pressed against the ratchet wheel by means of a compression spring Λ; The handwheel at the top is also provided with a rapid spring ρ for momentary shifting.
i ist die in dem Gehäuse angeordnete schalen- oder plattenförmige Isolierabdeckung, welche die stromführenden Teile und den gesamten Schaltmechanismus völlig abdeckt. i is the shell-shaped or plate-shaped insulating cover arranged in the housing, which completely covers the current-carrying parts and the entire switching mechanism.
