Comprise that also one is positioned at the back-moving spring of described sleeve, thereby movable contact spring better is electrically connected with center gear static contact and gear static contact.
Owing to be 360 degree rotations, many one of the gear ratio gear static contact of described gear, the concave surface of adjacent two teeth is corresponding with the gear static contact and on a radial line.
Be provided with four grooves on described base, the two ends of two elasticity location washer are inserted in the groove, thereby it is fixed on the base.
It is rounded that described movable contact spring is positioned at sleeve one end, and the other end is " T " font, thereby and make it better cooperate electrical connection with each gear static contact by rolling type.
The radius of described gear is greater than the radius of speed governing rotating shaft, thereby makes speed governing rotating shaft, gear and sleeve axial location in panel and base.
The utility model advantage compared with prior art is, can 360 degree clockwise and be rotated counterclockwise, simple in structure, compact, volume is little, production cost is low, and is safe in utilization, reliable.
