In, public contact 230 and four stepping contacts 231,232,233,234 are all formed by metal material.
Indexing rotating mechanism includes rotating shaft 25, location spring 24, ball 27 and the driving ring 17 being sheathed in rotating shaft 25, turns
Axle 25 includes locating slot 251 and ratchet 252, and dop 172, ball 27 are arranged on the end of location spring 24 also to drive ring 17 to include
Snapping in locating slot 251, drive the dop 172 of ring 17 to be stuck in ratchet 252, location spring 24 is arranged on fixing with shell 11
In sleeve pipe 111, one end of location spring 24 is connected with shell 11.
Drive mechanism includes the first drive link 15 and the second drive link 16;One end of first drive link 15 by rotating shaft 18 with
Shell 11 is rotationally connected, and the other end of the first drive link 15 is rotationally connected by one end of rotating shaft 20 with the second drive link 16, the
The other end of two drive links 16 is rotationally connected with driving ring 17 by rotating shaft 21.
Magnet exciting coil 12 and coiling framework 28 phase that calutron includes coiling framework 28, is wound on coiling framework 28
The fixed iron core 13 of contact and movable core 26, the upper end of movable core 26 is rotated even by rotating shaft 19 and the first drive link 15
Connect.
Back-moving spring 14, the upper end of back-moving spring 14 and movable ferrum it is provided with in the cavity that coiling framework 28 is centrally located
The lower end of the heart 26 connects, and the lower end of back-moving spring 14 is connected with fixed iron core 13, in order to provide generally upwards for movable core 26
Elastic force, the elastic force suffered by movable core 26 can by drive mechanism pass to drive ring 17 so that drive ring 17 reset.
In the present embodiment, about may be used to the distance of rotating shaft 18 in the junction of the second drive link 16 and the first drive link 15
Dynamic unshakable in one's determination 26 and first the junction of drive link 15 to 2 times of distance of rotating shaft 18.So, movable contact 22 realizes from one
