<p>A tap changer with semiconductor switching elements for uninterrupted switching between winding taps of a tapped transformer has two load branches connected with the winding taps of the tapped transformer and that each comprise a respective mechanical main contact that in stationary operation conducts current of the respective load branch and produces an electrical connection with a load shunt. Each load branch also has parallel to the respective main contact a series circuit consisting of a further respective mechanical contact as well as a respective semiconductor switch. These semiconductor switches are electrically connected together at a side remote from the respective contacts and lead to a mechanical transfer contact whose other side is connected with the load shunt. A connection of the main contacts as well as the further mechanical contacts is effected by a movable contact support.</p>
