Description

Die Erfindung betrifft ein Rastwerk für elektrische Drehschalter mit einem elektrische Schaltkontakte tragenden Isolierstoffsockel und einer die Schaltkontakte betätigenden, mittels einem angeformten Raststern mit einem federnden Rastglied zusammenwirkenden Schaltwalze.The invention relates to a locking mechanism for electrical rotary switches an insulating material base carrying electrical switch contacts and one the switch contacts actuating, by means of a molded locking star with a resilient locking member cooperating shift drum.

Bei den bekannten Rastwerken in elektrischen Drehschaltern ist ein besonderes federndes Rastglied, welches in der Regel aus einer Feder und einem mit dem Raststern der Schaltwalze zusammenwirkenden Druckstück, beispielsweise einer Rolle besteht, an dem Sockel gelagert. Dazu werden vielfach noch besondere Halterungsmittel benötigt.In the known locking mechanisms in electrical rotary switches is a special resilient locking member, which usually consists of a spring and a with the ratchet star of the shift drum cooperating pressure piece, for example one Role is stored on the base. In addition, special holding means are often required needed.

Aufgabe der Erfindung ist es, ein Rastglied zu schaffen, welches die Herstellungskosten und die Montagekosten des Schalters erheblich herabsetzt.The object of the invention is to create a locking member which the Manufacturing costs and the assembly costs of the switch significantly reduced.

Die Erfindung besteht darin, daß der Sockel aus einem elastischen, thermoplastischen Isolierstoff von hoher Temperaturbeständigkeit gebildet und diesem das Rastglied materialeinheitlich angeformt ist, Zweckmäßig ist dabei das Rastglied ein an seinen Enden mit dem Sockel verbundener flacher Steg, der mit einem Vorsprung, einer Wölbung od. dgl. in den Mulden des Raststerns einrastet.The invention consists in that the base consists of an elastic, thermoplastic insulating material of high temperature resistance formed and this the locking member is integrally formed of the same material, the locking member is expedient a flat web connected at its ends to the base, which with a projection, a curvature or the like. Engages in the recesses of the locking star.

Das Rastwerk nach der Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt. Es zeigt F i g. 1 einen Drehschalter von der Oberseite, F i g. 2 eine Ansicht des Schalters von der Seite, teilweise im Schnitt und F i g. 3 einen Querschnitt durch den Schalter.The locking mechanism according to the invention is shown in the drawing in one embodiment shown. It shows F i g. 1 a rotary switch from the top, FIG. 2 one View of the switch from the side, partially in section and FIG. 3 shows a cross section through the switch.

An dem Sockel 1 sind die Schaltkontakte 2 und 3 befestigt, die von der an dem Sockel gelagerten Schaltwalze 4 betätigt werden. Zur Verrastung in den jeweiligen Schaltstellungen ist der Schaltwalze 4 ein Raststern 5 angeformt, der mit einem Rastglied 6 zusammenwirkt. Dieses Rastglied 6 ist erfindungsgemäß bei dem aus einem elastischen, vorzugsweise thermoplastischen und insbesondere eine hohe Temperaturbeständigkeit aufweisenden Isolierstoff gebildeten Sockel 1, während dessen Preß- oder Spritzvorganges unmittelbar materialeinheitlich angeformt. Zweckmäßig ist das Rastglied ein zwischen zwei gegenüberliegenden Sockelwandungen liegender flacher Steg 6, der mit seinen Enden mit der jeweiligen Sockelwand verbunden ist. Zur sicheren Verrastung der Schaltwalze 4 ist der Steg 6 mit einem Vorsprung, einer Wölbung od. dgl 7 versehen, womit er in den Mulden des Raststerns 5 einrastet.The switch contacts 2 and 3, which are actuated by the switch drum 4 mounted on the base, are fastened to the base 1. For locking in the respective switching positions, a locking star 5 is formed on the shift drum 4, which interacts with a locking member 6. According to the invention, this latching member 6 is molded onto the base 1 formed from an elastic, preferably thermoplastic and, in particular, high temperature resistance insulating material, directly integrally formed during its pressing or injection molding process. The latching member is expediently a flat web 6 lying between two opposing base walls, the ends of which are connected to the respective base wall. For secure locking of the shift drum 4, the web 6 is provided with a projection, a bulge or the like 7, with which it engages in the depressions of the locking star 5.

Die Erfindung beschränkt sich nicht auf das dargestellte Ausführungsbeispiel, sondern es ist ohne weiteres möglich, das federnde Rastglied in beliebiger anderer Form dem Sockel 1 unmittelbar materialeinheitlich anzuformen.The invention is not limited to the illustrated embodiment, but it is easily possible to use the resilient locking member in any other Shape of the base 1 to be molded directly into the same material.
