Abstract

The invention relates to a switch contact subassembly ( 1 ) having a switch contact bridge ( 2 ) and a resilient element ( 3 ), for example, for an operating current of a switching element which switches an electric or hybrid motor vehicle. In order to be able to produce the switch contact subassembly ( 1 ) in a cost-effective and simple manner, there is provision according to the invention for the switch contact subassembly ( 1 ) to have a contact bridge retention member ( 4 ), the contact bridge retention member ( 4 ) having a securing base ( 14 ) for securing to an actuation member ( 15 ) for the switching element and at least one retention member ( 17 ) for positioning the switch contact bridge ( 2 ).

First claim

The invention claimed is:

1. A switch contact subassembly, comprising:
a switch contact bridge having a resilient element on which the switch contact bridge is resiliently supported counter to a switching direction,
a contact bridge retention member having a securing base for securing to an actuation member and having at least one retention member,
the resilient element being retained in a pre-tensioned state between the securing base and the switch contact bridge and the switch contact bridge pressing in a resilient manner against the retention member in a rest position (R) and the retention member and the securing base being constructed integrally with each other;
wherein the contact bridge retention member is constructed so as to have two retention members which rest on the securing base, the retention members being arranged so as to be opposite each other in a transverse direction of the switch contact bridge, to the at least one retention member has at least two stops for the switch contact bridge spaced apart from each other in a longitudinal direction (L) of the switch contact bridge.

2. The switch contact subassembly according to claim 1 , wherein the switch contact bridge is clamped in a secure manner in the contact bridge retention member by means of the resilient element and the switch contact subassembly may thereby be able to be handled in one piece.

3. The switch contact subassembly according to claim 1 , wherein the at least one retention member can be resiliently redirected away from the switch contact bridge.

4. The switch contact subassembly according to claim 1 , wherein the at least one retention member is formed so as to have two guiding faces for the switch contact bridge, which faces are directed away from each other and which extend parallel with the switching direction.

5. The switch contact subassembly according to claim 1 , wherein the two retention members define at least three bearing locations (P) for the switch contact bridge.

6. The switch contact subassembly according to claim 1 , wherein the two retention members each have at least one stop for the switch contact bridge.

7. The switch contact subassembly according to claim 1 , wherein the switch contact bridge has at least one abutment projection which protrudes in a transverse direction (Q) and which is in abutment against at least one retention member in the rest position (R).

8. The switch contact subassembly according to claim 1 , wherein the securing base is constructed so as to have a securing opening which extends in the switching direction (S).

9. The switch contact subassembly according to claim 8 , wherein the switch contact bridge has an assembly through-opening through which the securing opening is accessible.

10. The switch contact subassembly according to claim 9 , wherein the securing opening, the assembly opening and the resilient element delimit an assembly tunnel.

11. The switch contact subassembly according to claim 1 , wherein the switch contact subassembly has an actuation member to which the securing base of the contact bridge retention member is secured.

12. The switch contact subassembly according to claim 11 , wherein the actuation member is riveted to the securing base, a securing end of the actuation member forming a rivet head.

13. The switch contact subassembly according to claim 11 , wherein the actuation member has a flange at a securing end, whereby a surface-area of a support shoulder for supporting the securing base is enlarged.
