Description

Der Sägezahnschalter ist ein Vielstellenschalter. Er stellt eine Weiterentwicklung der bekannten Ty- pen mit Kugelrastung dar und kann mit einfachem oder mit Bürstenfedersatz für nahezu alle Stromstärken und Spannungen hergestellt werden; auch die Stufenzahl läßt sich variieren. Bei Anbringung einer Gewindebuchse zur Führung der Drehachse kann Einlochbefestigung erzielt werden. Die schnelle Schaltung von Kontakt zu Kontakt macht ihn für das Starkstromnetz sowie zur Schaltung von Induktivitäten geeignet (kleinste Funkenbildung beim Schaltvorgang). Sein Hauptvorteil liegt jedoch in der billigen Herstellungsmöglichkeit.The sawtooth switch is a multi-position switch. It represents a further development of the known types with ball detent and can be produced with a simple or with a set of brush springs for almost all currents and voltages; the number of stages can also be varied. If a threaded bushing is attached to guide the axis of rotation, single-hole fastening can be achieved. The fast switching from contact to contact makes it suitable for the high-voltage network as well as for switching inductivities (smallest spark formation during switching). However, its main advantage is that it is cheap to manufacture.

Der Gegenstand der Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel dargestellt. Die Drehachse a ist im Sägezahnbrett b sowie im Kontaktbrett c gelagert. Beide Bretter bestehen aus Isoliermaterial. Das Sägezahnbrett ist mit dem Kontaktbrett durch die Distanzsäulen d mit Hilfe der Schrauben e fest verbunden. Auf dem Sägezahnbrett ist die Sägezahnraste f in Rundform um die Drehachse befestigt; sie ist mit einer Lötfahne, die oberhalb des Sägezahnbrettes nicht sichtbar ist, metallisch verbunden. Auf dem Kontaktbrett sind die Kontakte g aufgenietet; sie sind mit Lätfahnen versehen, die unterhalb am Kontaktbrett sitzen und ebenfalls auf der Zeichnung unsichtbar sind. Die Drehachse ist in ihrer Länge zwischen dem Sägezahn- und Kontaktbrett mit einer eingef rästen Fläche versehen, auf der der Verbindungssatz mit Hilfe der Niete h angenietet ist.The object of the invention is shown in the drawing in an exemplary embodiment. The axis of rotation a is mounted in the sawtooth board b and in the contact board c. Both boards are made of insulating material. The sawtooth board is firmly connected to the contact board by the spacer columns d with the aid of the screws e. On the sawtooth board, the sawtooth catch f is attached in a round shape around the axis of rotation; it is metallically connected to a soldering lug, which is not visible above the sawtooth board. The contacts g are riveted to the contact board; they are provided with Lätfahnen, which sit underneath on the contact board and are also invisible on the drawing. The length of the axis of rotation between the sawtooth and contact board is provided with a milled surface on which the connection set is riveted with the aid of the rivet h.

Die beweglichen Schaltteile bestehen aus der Isolierplatte i sowie den auf ihr mit zwei Nieten be- .festigten Teilen" nämlich dein Federdruckhalter k, der Kontaktfeder 1. und der Druckfeder m. Zur sicheren Isolation der Kontakt- und Druckfeder von der Drehachse liegt das Isolierblatt ii zwischen Isolierplatte und Drehachse.The movable switch parts are made of the insulating plate I and the on her with two rivets loading .festigten parts "namely your spring pressurizer k, of the contact spring 1 and the compression spring m. In order to secure insulation of the contact and compression spring from the rotation axis is the insulation ii between the insulating plate and the axis of rotation.

In der Drehachse befindet sich unterhalb der Kontaktplatte der Anschlagbolzen o, der beim Schaltvorgang an die Anschlagstiftep anschlägt und damit verhindert, daß die Kontaktfeder von den Kontakten heruntergleitet.The stop bolt is located in the axis of rotation below the contact plate o, which strikes the stop pin p during the switching process and thus prevents that the contact spring slides off the contacts.

Die Betätigung des Sägezahnschalters erfolgt am Drehknauf q; die Kontaktfeder rastet in jeder Schaltstellung sicher in die Zahnlücken der Sägezahnraste ein.The sawtooth switch is operated using the rotary knob q; the contact spring engages securely in the tooth gaps of the sawtooth notch in every switching position.
