Switching contact and a method of producing the latter
A contact for an electrical switch has a first spring with an upper side and an opposite lower side, a second spring layered on the lower side, and a contact element located on the upper side and bonded to the second spring.
1. A contact for an electrical switch, comprising:
a first spring having an upper side, an opposite lower side, a first switching unit and a second switching unit, the first switching unit and the second switching unit arranged next to one another in a transverse direction perpendicularly to a longitudinal direction, the second switching unit connected to the first switching unit by a bridge in the transverse direction;
a second spring layered on the lower side of the first spring, and planar region of a contact section along an upper side of the second spring, the second spring having a first switching unit and a second switching unit, connected to the first switching unit by a bridge; and
a contact element disposed on the upper side of the first spring and bonded to the upper side of the second spring along the planar region.
2. The contact of claim 1 , wherein the contact element extends through the first spring.
3. The contact of claim 2 , wherein the contact element extends through an opening in the first spring.
4. The contact of claim 3 , wherein the contact element has a first projection.
5. The contact of claim 4 , wherein the first projection is moulded onto the contact element.
6. The contact of claim 5 , wherein the first projection extends through the opening.
7. The contact of claim 6 , wherein the first projection is welded to the second spring.
8. The contact of claim 7 , wherein the first projection is a rib.
9. The contact of claim 8 , wherein the opening is a slot.
10. The contact of claim 7 , wherein the contact element is welded to the first spring.
11. The contact of claim 10 , wherein the contact element has a second projection.
12. The contact of claim 11 , wherein the second projection is moulded onto the contact element.
13. The contact of claim 12 , wherein the second projection is welded to the first spring.
14. The contact of claim 13 , wherein the contact element is welded to the first spring and the second spring along a plurality of weld seams extending substantially parallel to a longitudinal axis of the first spring and the second spring.
15. The contact of claim 13 , wherein the bridge has a plurality of fastening openings.
16. The contact of claim 13 , wherein the first spring has a bend disposed in each of the first switching unit and the second switching unit.
17. The contact of claim 13 , wherein the first spring extends to a free end beyond the second spring in a longitudinal direction.
18. The contact of claim 17 , wherein the second spring has a reinforcement structure supporting the free end.
19. The contact of claim 13 , further comprising a plurality of contact elements.
20. The contact of claim 19 , wherein one contact element is disposed on each of the first switching unit and the second switching unit of the first spring.
