No, not that I can tell. I can whack the lever with my palm like someone might do in an emergency and it actuates the switch perfectly. The rod is 1/2" diameter solid round stock. When you put a bend in something it usually makes whatever it is more rigid.
As you can see in the pic the switch itself is mounted to an L bracket which is welded to the floor. The rod is supported by a small bracket that is also welded to the floor right when it enters the trunk. It's pretty solid.
