Problems solved by technology

[0002] In the contact system of the switch, the moving contact and the static contact contact the conduction circuit after a positive collision. However, due to the relatively stable structure, after a long time of use, the surface of the contact will accumulate dust, and the dust will cause contact. The resistance increases, or the dynamic and static contacts cannot be connected and other problems occur.

Abstract

The invention discloses a movable contact, comprising a contact body (1), the end of the contact body (1) is circular, and an electric contact (2) is arranged at the end, the electric contact The point (2) is not located at the center of the circular end, and the two sides of the middle position of the contact body (1) are respectively provided with a limit bar (3). The electrical contact in the present invention is not at the center of the end of the contact body. After colliding with the static contact, the contact body will be inclined so that dust will not accumulate and it can be used normally; The contact body is stuck in the moving contact seat, which ensures that it will not be misplaced after being tilted.

Description

technical field [0001] The invention relates to a movable contact. Background technique [0002] In the contact system of the switch, the moving contact and the static contact contact the conduction circuit after a positive collision. However, due to the relatively stable structure, after a long time of use, the surface of the contact will accumulate dust, and the dust will cause contact. The resistance increases, or the dynamic and static contacts cannot be connected and other problems occur. Contents of the invention [0003] In order to solve the problem that the surface of the movable contact is easy to accumulate dust, the present invention provides a movable contact, including a contact body 1, the end of the contact body 1 is circular, and there is a The electrical contact 2 is not located at the center of the circular end, and the two sides of the middle position of the contact body 1 are respectively provided with a limit bar 3 . [0004] The beneficial effects ...
