Ia have the next issue.

There is a lever  (blue) wich moves a gate. (gray). In one position the gate pushes one rod, and in the other position pushes the other rod. I want  to switch the rods movements just by dragging,, so when I drag and move the lever to one position and draig axially, one rod moves (being pushed by the gate) and the other stays, and of course the other case.

What are suggestions to do this just by dragging. I know it can be done by configurations, but I wanna do it just by placing and dragging the lever.(If you wanna make a presentation about the mechanism, it looks weird and "tricked" going to menus and changing configurations every time you wanna switch)
