| description | The utility model relates to the technical field of electrical switches, in particular to a dual-power change-over switch, which comprises a shell and a contact assembly, and is characterized in that the shell is provided with an accommodating cavity; the contact assembly is arranged in the accommodating cavity, the contact assembly comprises a conversion contact, a load contact and a power supply contact, and the load contact and the power supply contact are both arranged in the rotation range of the conversion contact; the shell is provided with an exhaust port and an arc blocking piece protruding out of the inner wall of the shell, and the arc blocking piece is located on one side of the exhaust port and used for guiding electric arcs to the exhaust port. According to the invention, arc discharge is facilitated, so that ablation of parts in the switch can be reduced, and the breaking capacity of the switch is improved.
