Abstract:
A disconnect switch, especially a movable and stationary contact device on the disconnect switch. A movable and stationary contact device for a disconnect switch, comprising a movable contact (1) and a stationary contact (2). The movable contact (1) and the stationary contact (2) are respectively provided with a movable contact point (11) and a stationary contact point (21). The stationary contact (2) comprises a transverse edge (22). One end of the transverse edge (22) is connected to an electrical connection terminal (23), and the other end thereof is provided with a vertical edge (24). The stationary contact point (21) is provided on the vertical edge (24). The movable contact (1) is provided at one side of the vertical edge (24) of the stationary contact. The movable contact point (11) and the stationary contact point (21) are provided corresponding to each other. The part of the movable contact (1) below the movable contact point (11) is connected to a wire (12). The solution provides a novel movable and stationary contact device for a disconnect switch, characterized in that the movable contact point closely contacts the stationary contact point in a closed state, and the arc can be well guided to the lower part of the vertical edge of the stationary contact during opening.
