Beim Öffnen des Vakuumschalters legt die Schub-Eine solche Anordnung kann beispielsweise so 40 stange 10 zunächst den Weg 9 zurück, bevor die elaaufgebaut sein, wie sie in F i g. 1 dargestellt ist.

Inside the It is the contact point of a vacuum switching element required, which is normally connected as a contact load in front of the end of the movable contact pin 5 atmospheric pressure by an additional. Between the disc 2 and the pierced one Support force. This is intended to simultaneously be the side of the driver 1 according to the Eriinein To compensate for the manure occurring over time, an elastic intermediate layer 4 is provided. Contact erosion can be brought about so that there is 35 For this purpose, both disc springs and coils can be used Has proven to be useful, the movable springs used appropriate spring characteristics Contact bolts of a vacuum switching element become in. In the closed state of the vacuum closed State by a switch in the closing direction, the elastic intermediate layer 4 is relaxed, acting spring force to load. When the vacuum switch is opened, the push-one sets Such an arrangement can, for example, so 40 rod 10 first the way 9 back before the ela built up be as shown in FIG. 1 is shown. Here, the intermediate layer 4 is in contact with the disk 2 engages around the driver 1 of the actuating organ tion comes.

Erst dann wird die Scheibe 2 mithöht wird. Allerdings treten bei dieser Anordnung genommen und der Vakuumschalter geöffnet.

Only then is the disk 2 also increased will. However, when this arrangement occurs, the vacuum switch is taken and opened. the when the contact path is opened, the high mechanical force acting on the disk 2 increases steadily Cranes open because the driver 1 of the actuator closes, so that the accelerating cranes open goose can only be reduced significantly after a certain time with a finite 50. The mechanical beanchen This increases the speed on driver 2 of the stress on the vacuum switching element Removable contact bolt suddenly hits, which is also reduced and at the same time its vitality Acceleration forces occur. This increases the duration.
