The utility model relates to the technical field of high-voltage alternating-current isolating switches and specifically relates to a turnover conductive structure of a high-voltage alternating-current isolating switch. The turnover conductive structure comprises a static contact seat, contact fingers, contacts and a conductive tube. The contacts are of a strip-shaped structure of which the cross section is U-shaped, and the contacts are respectively sleeved on installation plates at the two sides of the conductive tube and are connected with the installation plates through bolts; the outer sides of the contact fingers are arc-shaped, namely connection parts of the contact fingers and the outer ends of horizontal plates of the static contact seat are arc-shaped; insulating pads are arranged between springs and the horizontal plates of the static contact seat; positioning plates are arranged between the springs and the contact fingers, and one ends of the positioning plates are connected with the static contact seat; and the positioning plates are provided with positioning grooves in which the contact fingers can be placed, and the inner sides of the contact fingers extend into the positioning grooves. The turnover conductive structure has the characteristics of being simple and reasonable in structure, good in conductivity and capable of avoiding heating of a conductive loop.
