Abstract: A de-energized tap changer for transformers comprises a frame of insulating material, a slide which carries movable contacts, the slide being displaceable in the frame, and a drive for the slide. The frame of the tap changer is manufactured in one piece and consists of a terminal bar with attachment means for connections from the transformer windings, a carrier member carrying the drive, and cross-bars connecting the terminal bar and the carrier member. The movable slide is displaceable in grooves in the cross-bars and can be inserted in the grooves only when situated outside its ordinary working area.
