Abstract: Contact unit for a tap changer including a contact ring having a central axis, a plurality of fixed contacts arranged at a distance from the contact ring in different radial directions, and a moving contact arranged rotatable about the central axis of the contact ring and adapted to electrically connect the fixed contacts one at a time with the contact ring. The moving contact includes two elongated contact elements. Each of the contact elements includes a first contact area for providing electrical contact with the fixed contacts and a second contact area for providing electrical contact with the contact ring. The moving contact is designed so an electric path is formed between the first and second contact area. The first and second contact areas are positioned on opposite sides of a plane orthogonal to a longitudinal axis of the moving contact and including the central axis of the contact ring.
