Switching device arrangement

1. A switching device arrangement, comprising:

a first contact set and a second contact set, said first contact set being disposed for movement relative to said second contact set in order to produce a switching contact between respective contacts;

said first contact set having an arcing contact piece and a nominal current contact piece movably disposed relative to one another;

a kinematic chain connected to said nominal current contact piece configured to impress a movement onto said nominal current contact piece;

a stationary counter bearing; and

a gearing forming an operative connection between said stationary counter bearing and said arcing contact piece, wherein a relative movement is effected between said nominal current contact piece and said arcing contact piece via said gearing;

said stationary counter bearing being coupled to said gearing via a slotted guide path.

2. The switching device arrangement according to claim 1 , wherein said stationary counter bearing is configured to control a transmission behavior of said gearing.

3. The switching device arrangement according to claim 1 , wherein said gearing is mounted on said first contact set.

4. The switching device arrangement according to claim 3 , wherein said gearing is mounted on said nominal current contact piece.

5. The switching device arrangement according to claim 1 , wherein said nominal current contact piece is mounted movably in relation to said stationary counter bearing.

6. The switching device arrangement according to claim 1 , wherein said gearing includes a control element guided on said stationary counter bearing.

7. The switching device arrangement according to claim 1 , wherein the gearing comprises a pivot element pivotally attached to said nominal current contact piece.

8. The switching device arrangement according to claim 1 , wherein said gearing comprises a lever arrangement.

9. The switching device arrangement according to claim 1 , wherein said gearing is a first gearing and said kinematic chain comprises a second gearing for coupling in a movement at said nominal current contact piece.

10. The switching device arrangement according to claim 9 , wherein said second gearing is stationarily mounted.

11. The switching device arrangement according to claim 1 , wherein said kinematic chain includes an electrically insulating transmission element.

12. The switching device arrangement according to claim 11 , wherein said electrically insulating transmission element is an insulating nozzle protruding into a clearance between the contacts.

13. The switching device arrangement according to claim 1 , which comprises a common drive apparatus commonly driving said first and second contact sets.

14. The switching device arrangement according to claim 1 , wherein said gearing is a first gearing and said kinematic chain includes a second gearing, and wherein said first gearing and said second gearing are arranged in succession in a direction of a flow of force.

15. The switching device arrangement according to claim 14 , wherein said second gearing includes a stationarily mounted rotation element.

16. The switching device arrangement according to claim 15 , wherein said rotation element is a gearwheel.

17. The switching device arrangement according to claim 15 , wherein said rotation element is a pivot lever.

18. The switching device arrangement according to claim 14 , wherein one of said first and second gearings is configured to convert a driving movement into an oppositely directed driven movement and a respectively other gearing is configured to amplify the oppositely directed movement.

19. The switching device arrangement according to claim 14 , wherein said second gearing converts the driving movement into the oppositely directed driven movement and said first gearing amplifies the oppositely directed movement.
