But for the 320/360s if the switch did go past the limit, there is a risk that the flap push rod will contact the spar causing it to bend resulting in an asymetric flap. This would not be good. Regardless of which system I like the idea of mechanical stops slightly beyond the electrical limits to assure there is no possibility of a bent rod. There have been several instances of bent push rods. In one case, the aircraft was in a flare and near the ground so no serious harm done. Some time in the past the push rod diameter was increased and a caution to insure that the rode did not contact the aft spar was issued.
