A stepping switch S has a housing filled with a dielectric liquid and devices for compensating for thermally related volume variations of the liquid. A bellows/compensator switch K is used to take up the volume variation of the dielectric liquid. The compensation device forms a compact structural component devoid of an additional conduit and mounted directly on the switch. The inventive expansion tank configuration makes it possible to integrate pressure-relieving devices and to place the monitoring units of the stepping switch in a space-saving manner. |
