Isolating switch operation principle of the present invention is as follows:
When clockwise direction rotatablely moves under the effect of handle 9 in external force, the moment of handle torsion spring 11 strengthens gradually and drives 8 motions of U-shaped connecting rod simultaneously, then cause that U-shaped connecting rod 8 drives 22 motions of moving contact torsion spring, and because 22 straddle mountings of moving contact torsion spring are in the both sides of moving contact rack 18, so when 22 motions of moving contact torsion spring, the moment of torsion that acts on moving contact rack 18 both sides makes moving contact rack 18 do counterclockwise to rotatablely move around its moving contact fixed axis 5.Fastening because of moving contact 20, gusset piece 19 and moving contact rack 18 threes again, so when moving contact rack 18 motions, moving contact 20 also its moving contact fixed axis 5 is done counterclockwise to rotatablely move and is close with fixed contact 16.On the other hand, in the time of moving contact rack 18 motions, also driven indication piece 13 and done counterclockwise to rotatablely move around its indication piece fixed axis 6 by indication piece trace 7.
When the continuation clockwise direction rotatablely moves certain angle under the effect of handle 9 in external force, handle button spring 11 acts on moment on the handle 9 acts on the moment on the handle 9 greater than external force moment, even under the effect that does not have external force, handle 9 also can continue to rotatablely move as clockwise direction fast under the effect of handle button spring 11, and the effect by the U-shaped connecting rod makes dynamic and static contact closed fast then.Indication piece shows closure state at this moment.
When counterclockwise rotatablely moving under the effect of handle 9 in external force, the moment of handle torsion spring 11 strengthens again gradually, because the effect of moving contact torsion spring 22, dynamic and static contact is kept closed, when handle 9 continued counterclockwise to rotatablely move certain angle, even without the external force effect, handle 9 was under the effect of handle torsion spring 11 and moving contact torsion spring 22 moments, also can continue to do fast counterclockwise to rotatablely move, and dynamic and static contact be separated fast by the effect of U-shaped connecting rod 8.Indication piece shows off-state at this moment.
