Top, radially can freely rotate；The galianconism, it is long-armed be respectively and vertically fixed in the rotating shaft, both are parallel to each other；
The bottom of the first axle be fixed on it is described it is long-armed on, its top is fixed on the free end of the galianconism；The first axle is passed through
The first long strip through hole set in the spring installation axle；The long-armed free end is provided with the second long strip through hole, described second
Axle can be under the promotion of the driving lever along second long strip through hole slip；The long-armed bottom, which is fixed, is formed with circular cylindrical projection
Rise.
Specifically, the bottom of second axle is formed with chassis or fixture block；Shape on the second long strip through hole inwall
The groove that chassis described in Cheng Youyu or fixture block match；Chassis or fixture block are slided along groove.
Or following connected mode can also be changed into：The second axle bottom sets groove, the inside of second long strip through hole
Provided with track, groove slides along the track.
The energy-stored spring operating mechanism of the low voltage isolation switch be using the idle stroke in spring installation axle and rotary shaft come
Ensure that the operation speed of operating personnel is unrelated with the action switched, thus contact can be made quickly to divide, close, it is to avoid to keep apart
Close contact burnout failure.In addition, also having reasonable in design, simple, cost low, without entering to former low voltage isolation switch structure
The advantages of row is changed.
