Abstract

A switching structure of moving contacts and fixed contacts of a tap selector comprises an insulating switch base plate at least two fixed contacts (101 102 103; 401.1 401.2 … 401.9) at least one rotary shaft (300; 405) and at least one arc shaped conductor (200; 404.1 404.2 404.3). The at least two fixed contacts are fixed on the insulating switch base plate in at least one row and at intervals and the inner end of each of the at least two fixed contacts is in electric connection with a tapping winding corresponding to a transformer. At least two moving contacts (310 320 330; 403.1 403.2 403.3) are evenly arranged on the rotary shaft and the two moving contacts are in electric connection. The at least one arc shaped conductor corresponds to the at least two fixed contacts which are arranged in at least one row. The arc shaped conductor and the outer end (101a 102a 103a) of each of the at least two fixed contacts in at least one row are located at the same circumference with the center of the rotary shaft as the center of the circle of the circumference and when one of the moving contacts is switched between the two fixed contacts the other moving contact must be in electric connection with the arc shaped conductor. According to the switching structure connecting conductors inside a switch are eliminated all parts are fixed reliably installation is convenient and hidden faults are reduced.
