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 moving contact. The moving contact comprises a contact body (1); an end portion of the contact body (1) is circular and is provided with an electrical contact (2); the electrical contact (2) is not located at the center of the circular end portion of the contact body (1); a boss (3) is arranged next to the electrical contact (2); and the height of the boss (3) is smaller than the height of the electrical contact (2). According to the moving contact of the invention, the electrical contact is not located at the center of the end portion of the contact body (1), and therefore, after the moving contact collides with a fixed contact, the contact body will tilt, and dust will not be accumulated, and the normal use of the moving contact can be ensured.

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, which includes 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 a boss 3 is provided beside the electrical contact 2 , and the height of the boss 3 is smaller than that of the electrical contact 2 . ...
