Abstract

An arrangement for an electrical switching device is disclosed. The arrangement for an electrical switching device comprises a contact spring and a component attached to the contact spring. The component has an edge running in an inclined manner with respect to a longitudinal direction of the contact spring. The component also has at least two switching state positions and a transition phase between the switching state positions, and abuts the contact spring along the edge in the transition phase.

First claim

What is claimed is:

1. An arrangement for an electrical switching device, comprising:
a contact spring; and
a component attached to the contact spring at a fastening location and having an edge extending in an inclined manner with respect to a longitudinal direction of the contact spring, the component having at least two switching state positions and a transition phase between the switching state positions, the component movable with respect to the contact spring between the two switching state positions and abutting the contact spring along the edge in the transition phase, the edge abutting the contact spring at an abutting location positioned at an intersection of the edge with a line extending through the fastening location orthogonal to the longitudinal direction.

2. The arrangement for an electrical switching device of claim 1 , wherein the edge extends over a width of the contact spring.

3. The arrangement for an electrical switching device of claim 2 , wherein, in one switching state position, the contact spring abuts the edge over a width of the contact spring.

4. The arrangement for an electrical switching device of claim 1 , wherein the edge extends in a width direction of the contact spring at least up to a point aligned with the fastening location.

5. The arrangement for an electrical switching device of claim 1 , wherein the edge is positioned on an end face of the component.

6. The arrangement for an electrical switching device of claim 5 , wherein the edge faces a contacting location of the contact spring.

7. The arrangement for an electrical switching device of claim 1 , wherein the abutting location moves in a longitudinal direction and/or a width direction of the contact spring in the course of the transition phase.

8. The arrangement for an electrical switching device of claim 7 , wherein the abutting location moves away from the fastening location in the course of the transition phase.

9. The arrangement for an electrical switching device of claim 7 , wherein the abutting location moves along a continuous line over the contact spring in the course of the transition phase.

10. The arrangement for an electrical switching device of claim 9 , further comprising a core pole having a front face.

11. The arrangement for an electrical switching device of claim 10 , wherein a projection of the front face in a longitudinal direction of the core pole extends onto the component.

12. The arrangement for an electrical switching device of claim 11 , wherein the abutting location remains outside of the projection.

13. The arrangement for an electrical switching device of claim 1 , wherein the component is an armature.

14. The arrangement for an electrical switching device of claim 13 , wherein the contact spring forms a restoring spring of the armature.

15. The arrangement for an electrical switching device of claim 14 , wherein the restoring spring has a bulge.

16. The arrangement for an electrical switching device of claim 15 , further comprising a magnet system.

17. The arrangement for an electrical switching device of claim 16 , wherein the contact spring is arranged externally from the magnet system.

18. The arrangement for an electrical switching device of claim 1 , wherein, in one of the switching state positions, the contact spring is spaced apart from the edge.

19. The arrangement for an electrical switching device of claim 1 , wherein, in one of the switching state positions, a distance between the edge and the contact spring varies along the length of the edge.

20. The arrangement for an electrical switching device of claim 1 , wherein the edge is curved.

21. The arrangement for an electrical switching device of claim 1 , wherein the edge is formed by a protrusion extending from a surface of the component.
