Summary:Disclosed is a switching mechanism of a dual-power switch. The problem that the arc extinguishing effect is poor due to the fact that the running angle and the rotating angle of a moving contact of anexisting dual-power switch are too small is mainly solved. the first power supply assembly comprises a first static contact (11). The second power supply assembly comprises a second static contact (21); the rotating piece is arranged between the first static contact and the second static contact, and an included angle c formed by a straight line a where the axis of the moving contact in contact with the first static contact is located and a straight line b where the axis of the moving contact in contact with the second static contact is located is larger than 180 degrees. According to the switching mechanism of the dual-power switch provided by the utility model, after the moving contact is separated from one static contact, the moving contact can be connected with the other static contact only by rotating a larg
