Disclosed is a change-over structure between a moving contact and a static contact of a tap selector, including an insulation changer base plate, and further including at least two static contacts, fixed on the insulation changer base plate in at least one column at intervals, where inner ends of at least two static contacts are electrically connected to two tap windings of a transformer respectively; at least one rotation shaft, where at least two moving contacts are evenly distributed on the one rotation shaft, and the at least two moving contacts are electrically connected to each other; and at least one arc-shaped conductor corresponding to the at least two static contacts in at least one column, where the arc-shaped conductor and outer ends of the at least two static contacts in at least one column are located at the same circumference with a center of the rotation shaft as a circle center, and when one of the moving contacts is changed over between the two static contacts, the other moving contact is certainly electrically connected to the arc-shaped conductor. Through the present invention, connection conductors in the changer are omitted, so that each component is fixed and reliable and is convenient to mount, and hidden fault troubles are reduced.
