[0018] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
[0019] Such as figure 1 with figure 2 As shown, the dual power switch of the present invention includes two switching mechanisms and a moving contact operating mechanism for switching the two switching mechanisms on and off. The two switching mechanisms are symmetrically arranged with respect to the moving contact operating mechanism, and each group of switching mechanisms It includes a static contact and a moving contact group. The moving contact group includes more than one moving contact piece. The moving contact pieces are coaxially connected by a first rotating shaft 6, and the moving contact piece is provided with an upper moving contact piece. The contact 22 and the lower moving contact 21. The static contact includes an upper static contact 11 for opening and closing with the upper moving contact 22 and a lower static contact for opening...
