Abstract

A contact bridge arrangement for an electrical switch is disclosed that has a contact bridge holder and a contact bridge. The contact bridge holder is monolithically formed with a spring. The contact bridge is held on the contact bridge holder and movable along an actuating direction. The contact bridge is pressed against the contact bridge holder by the spring.

First claim

What is claimed is:

1. A method of manufacturing a contact bridge arrangement for an electrical switch, comprising:
producing a monolithic contact bridge holder having a guiding stop and a spring by stamping; and
positioning a contact bridge on the contact bridge holder movable along an actuating direction and pressed against the guiding stop by the spring, the contact bridge having a pair of spacers extending from an underside of the contact bridge, the spacers separated from one another in a direction transverse to a longitudinal direction of the contact bridge and bearing against the spring.

2. A contact bridge arrangement for an electrical switch, comprising:
a contact bridge holder having a guiding stop and monolithically formed with a spring; and
a contact bridge held on the contact bridge holder, movable along an actuating direction, and pressed against the guiding stop by the spring, the contact bridge having a pair of spacers extending from an underside of the contact bridge, the spacers separated from one another in a direction transverse to a longitudinal direction of the contact bridge and bearing against the spring.

3. The contact bridge arrangement of claim 2 , further comprising an actuator system attached to the affixing site.

4. The contact bridge arrangement of claim 2 , wherein the spring has an affixing site in a middle region and two opposite ends.

5. The contact bridge arrangement of claim 4 , wherein the spring has a stiffening structure extending perpendicular to the longitudinal direction.

6. A contact bridge arrangement for an electrical switch, comprising:
a contact bridge holder:
(a) movable in an actuating direction and in a deactuating direction opposite the actuating direction, and
(b) having:
(1) a pair of guiding legs, each guiding leg having a guiding stop, and
(2) a spring monolithically formed as part of the contact bridge holder; and

a contact bridge:
(a) held in the contact bridge holder between the pair of guiding legs, and
(b) having a bridge stop pressed by the spring against each guiding stop of each guiding leg of the contact bridge holder and a pair of spacers extending from an underside of the contact bridge, the spacers separated from one another in a direction transverse to a longitudinal direction of the contact bridge and bearing against the spring.

7. The contact bridge arrangement of claim 1 , wherein the spacers are monolithically a part of the contact bridge.

8. The contact bridge arrangement of claim 1 , wherein both spacers are positioned at one end of the contact bridge and form a U-shaped cross-section transverse to the longitudinal direction.

9. The contact bridge arrangement of claim 1 , wherein the spring is a leaf spring.

10. The contact bridge arrangement of claim 9 , wherein the spacers space the leaf spring from the underside of the contact bridge.

11. The contact bridge arrangement of claim 9 , wherein the leaf spring extends substantially transverse to the actuating and deactuating directions.

12. The contact bridge arrangement of claim 11 , wherein the leaf spring extends substantially parallel to a longitudinal direction of the contact bridge.

13. The contact bridge arrangement of claim 12 , wherein the leaf spring is curved toward the underside of the contact bridge.

14. The contact bridge arrangement of claim 9 , wherein the leaf spring has a tapered section between the middle of the leaf spring and at least one end.

15. The contact bridge arrangement of claim 14 , wherein the leaf spring has a widened section at least at one end.

16. The contact bridge arrangement of claim 15 , wherein the widened section extends transverse to a longitudinal direction of the contact bridge.

17. A contact bridge arrangement for an electrical switch, comprising:
a contact bridge holder:
(a) movable in an actuating direction and in a deactuating direction opposite the actuating direction, and
(b) having:
(1) a pair of guiding legs, each guiding leg having a guiding stop, and
(2) a spring monolithically formed as part of the contact bridge holder;

a contact bridge:
(a) held in the contact bridge holder between the pair of guiding legs, and
(b) having a bridge stop pressed by the spring against each guiding stop of each guiding leg of the contact bridge holder and a spacer extending from an underside of the contact bridge and bearing against the spring; and

a contact element extending through the contact bridge and forming the spacer.

18. A contact bridge arrangement for an electrical switch, comprising:
a contact bridge holder:
(a) movable in an actuating direction and in a deactuating direction opposite the actuating direction, and
(b) having:
(1) a pair of guiding legs, each guiding leg having a guiding stop, and
(2) a leaf spring monolithically formed as part of the contact bridge holder, the leaf spring having a tapered section between a middle of the leaf spring and at least one end; and

a contact bridge:
(a) held in the contact bridge holder between the pair of guiding legs, and
(b) having a bridge stop pressed by the spring against each guiding stop of each guiding leg of the contact bridge holder and a spacer extending from an underside of the contact bridge and bearing against the spring.

19. The contact bridge arrangement of claim 18 , wherein the leaf spring has a widened section at least at one end.

20. The contact bridge arrangement of claim 19 , wherein the widened section extends transverse to a longitudinal direction of the contact bridge.
