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 Point (2) is not at the center of this circular end. The electric contact in the present invention is not at the center of the end of the contact body, and after colliding with the static contact, the contact body will be tilted, so that dust will not accumulate, and its normal use can be guaranteed.

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 An electrical contact 2 which is not located in the center of the circular end. [0004] The beneficial effects of the present invention are: [0005] The electric contact in the present invention is not at the cente...
