Abstract

Die Erfindung bezieht sich auf einen einen Federkraftantrieb aufweisenden elektrischen Schalter, bei dem ein Energiespeicher vorgesehen ist, der eine zwischen einem feststehenden Widerlager (17) und einem beweglichen Widerlager (18) spannbare, in einer Stützanordnung (20,21,22) gehaltene Speicherfeder (19) aufweist, und bei dem die mit einem Anschlag (23) für das bewegliche Widerlager (18) versehene Stützanordnung gemeinsam mit der Speicherfeder (19) und den beiden Widerlagern (17, 18) eine eigenständige Baueinheit bildet, die im Bereich nur eines der beiden Widerlager an einem Tragwerk (5) positioniert ist.The invention relates to a spring force drive having electrical switch, in which an energy storage is provided, the one between a fixed Abutment (17) and a movable abutment (18), storage spring held in a support arrangement (20, 21, 22) (19), and in which the with a stop (23) for the movable abutment (18) provided support arrangement together with the storage spring (19) and the two abutments (17, 18) forms an independent unit, which in Area of only one of the two abutments on a supporting structure (5) is positioned.

Um eine hohe Lebensdauer des Energiespeichers auch bei häufigem Leerschalten zu gewährleisten, besteht die Stützanordnung aus einem U-förmigen Plattenelement (20) und zwei quer zur Wirkrichtung der Speicherfeder (19) nebeneinander verlaufenden Stabelementen (21,22), an denen der Anschlag für das bewegliche Widerlager (18) als Stoßdämpfer (23) ausgebildet ist. Hierbei durchgreifen die beiden Stabelemente (21,22) die Seitenflächen (29) des U-förmigen Plattenelementes (20) und sind am Tragwerk (5) gehaltert.

Figure 00000001
In order to ensure a long service life of the energy store even when it is frequently switched off, the support arrangement consists of a U-shaped plate element (20) and two rod elements (21, 22) which run alongside one another transversely to the direction of action of the storage spring (19) and on which the stop for the movable abutment (18) is designed as a shock absorber (23). The two rod elements (21, 22) pass through the side surfaces (29) of the U-shaped plate element (20) and are held on the supporting structure (5).
