Mating problem in assembly

Hello everybody.

I am using SW2010.

I have this assembly (to be completed) where the part named ‘cam’ is turning counterclockwise and hits the part named ‘wheel’ only for a short time, moving it. When the cam passes, the wheel will go back in his original position, using a spring (I didn’t draw it yet). Basically it works like a mechanical switch (maybe the definition is not correct).

Right now the only mate between the cam and the wheel I was able to put is the tangent named ’TANGENT CAM + WHEEL’, but doesn’t let me turn the cam for 360 degrees. I think this is going to be deleted.

Does anyone know how to do this ???

I am more interested to get this done in the model, this is my priority.

If it is not possible to do this in the model, I would try in the Motion Study, but I don’t know if would be better an Animation or a Basic Motion.

I have attached assembly and parts file and 4 pictures of what I would like to do.

Thanks for your help.
