The invention discloses a contact structure of a dual-power switch. An operating mechanism drives an insulating rotating shaft to rotate for closing. A moving contact rotates along with the insulatingrotating shaft until the moving contact collides with a static contact assembly. The collision applies an acting force opposite to the rotating direction of the insulating rotating shaft to the moving contact. The acting force is conducted to a collision buffer mechanism through the moving contact. The eccentric pressure applied by an eccentric pressure piece is mutually counteracted. The movingcontact and the static contact assembly are kept in a joint state. The design has the advantage that the design has the advantage of being simple in structure, the width of the moving contact is smaller than that of the opening of the accommodating cavity; the moving contact can penetrate through the containing cavity and rotate around the positioning structure in the containing cavity, meanwhile,the opening width of the c
