Abstract
Insbesondere bei Kraftfahrzeugen werden Schalter mit einem Metallgehäuse und einem Sockel aus Kunststoff als Rückfahrschalter, Getriebeschalter, Temperaturschalter oder dergleichen eingesetzt. Der Zink-Druckguß, aus dem das Schaltergehäuse üblicherweise besteht, gibt jedoch bei höheren Temperaturen nach, so daß der lediglich durch eine endseitige Umfangslippe in dem Druckgußgehäuse ge sicherte glatte zylindrische Kunststoffsockel sich aus seiner Befestigung an dem Druckgußgehäuse lösen kann. Dies wird gemäß der Erfindung in besonders einfacher Weise dadurch vermieden, daß der Sockel (2) des Schalters (1) einen nach außen hervorstehenden Halteflansch (7) aufweist, daß die Umfangslippe (6) an einer vom Sockel (2) nach außen gerichteten schrägen Fläche (10) des Sockels anliegt, und daß an der den Sockel (2) umgebenden Hülse (5) mindestens zwei, vorzugsweise drei oder vier Einprägungen oder Einkerbungen (8) über den Umfang des Halteflansches (7) verteilt angeordnet sind, die den Halteflansch (7) an der der Umfangslippe (6) zugewandten Flanschseite sichernd untergreifen. Switches are used in particular in motor vehicles a metal housing and a plastic base as Reversing switch, gear switch, temperature switch or the like used. Die-cast zinc, from which the switch housing usually exists, but there are at higher temperatures, so that the only by an end peripheral lip in the die-cast housing ge smooth cylindrical plastic bases secured themselves can solve its attachment to the die-cast housing. This becomes particularly simple according to the invention Way avoided in that the base (2) of the switch (1) an outwardly projecting retaining flange (7) has that the peripheral lip (6) on one of the base (2) outward sloping surface (10) of the Base rests, and that on the base (2) surrounding Sleeve (5) at least two, preferably three or four Impressions or notches (8) on the scope of the Holding flange (7) are arranged distributed, the Holding flange (7) on the peripheral lip (6) facing Reach in securely under the flange side.
