mating cylinder and chamfered area

[eex23]

Hello,

We have to design a kind of switch. Cylinder (part 2.prt) rolls on the top area of the part 1 (1.prt), when the part 1 moves. Switching of the electrical contacts occures when the cylinder falls in to the pocket with chamfered edges.
The question should be: how to mate surface with the pocket (with chamfers) and cylinder correctly? I want to move part 1, and the cylinder should stay fixed, only it should follow the surface of the block.
I tried to extract and then sew the faces of the block, but in the assembly I can only select one face for tangent mating condition.
Parts are in the attached archive AAA.rar.

Sorry for my bad english.


Thanks.

Forgot to mention:
we are using NX 4.0.4.2 mp10

Here is a solution which involves creating a single smooth face (sheet body) which is used for the Tangent mating condition. You can move (drag) the cylinder using Reposition Component and you will see that it maintains contact with your part as you desire.

Thanks John.

It works as I expected.

One more question.

Please look at the attached picture. There is situation as John solved above, but it has one additional rod with chamfered pocket (shorter). Is it possible to mate black cylinder to these both rods in a way, that black cylinder will follow any of these two moving rods?
Each rod can move separatly of each other, and because these chamfered pockets are of different lengths, so cylinder should follow any of them.

thanks.
