The invention relates to a switching arrangement () with a pre-selector () for a power transformer () which has multiple windings (). The pre-selector is designed to optionally connect at least one first winding () to one of the two end contacts () of at least one second winding (). At least one first switch is arranged in the connection between the pre-selector () and the first winding (), thereby allowing the pre-selector to be switched in an arc-free manner and thus in a gas-free manner as well.

Switching system with preselector

The invention relates to a step switch, comprising a pre-selector and a fine selector. The invention is characterized in that the step switch has a connection () between the pre-selector and the fine selector (), at least one coupling switch () being arranged in said connection. A pre-selector can be switched in a largely gas-free manner by means of said switchable connection with the aid of the fine selector.
