Abstract
An on-load tap changer for uninterrupted switching between different winding taps of a regulating winding of a tapped transformer in a transformer housing has at least one selector inside the housing for power-free selection of the respective winding tap of a tapped transformer that is to be switched over to and directly juxtaposed with the winding taps. It also has, spatially separate from the selector, a load-changeover switch for the actual switching from the connected to the new, preselected winding tap.
