Abstract
An insulating supporting frame of a multi-pin switch arrangement has a box-shaped base part and an insulating supporting part arranged over it. Insulating housings encompassing the vacuum switch tubes are formed onto a wall part. On the rear, bearing parts which are parallel to one another and at a distance from one another are cast onto the wall part, the bearing parts being connected to a top wall of the box-shaped base part. A drive shaft of a spring-force drive is mounted on the bearing parts. The spring-force drive is connected via a linkage to a movable switch contact of the vacuum switch tube. The one-piece insulating supporting frame is constructed in such a way that practically all the parts of the switch arrangement can be arranged on it.
