Description

Technical Field

[0001] The utility model relates to the technical field of switch devices, in particular to a rotary contact switch device. Background Art

[0002] At present, the structure of the moving and static contacts of each layer of the rotary electrical switch generally includes a shell, the middle part of the shell includes a space for installing the rotary contact assembly, and four installation positions for static contacts are evenly distributed around the space; wherein, the rotary contact assembly includes a conductive part and an insulating part, the conductive part is symmetrically arranged on the same straight line, and the insulating part is outside the conductive part. On the four installation positions of the shell, a group of diagonally arranged installation positions are selected to install the static contacts respectively, and the static contacts include a contact part for contacting with the rotary contact and a connecting part for connecting the wire, and the two contact parts are obliquely symmetrically located on the same straight line. When the rotary contact assembly rotates until the two conductive parts are in contact with the two contact parts respectively, the rotary contact and the static contact are connected. However, the structure of the existing rotary electrical switch is too complicated and is not suitable for simple working conditions such as elevators. Moreover, the contact structure of the existing rotary electrical switch is single and unstable, which easily causes the rotary contact and the static contact to fail to contact, and is time-consuming and labor-intensive, thereby causing the rotary switch to fail to be used normally.
