>I'm not aware of a SB regarding the magnetic limit switches since I
haven't heard until recently that anyone else has had the problem, e.g.,
the
magnetic rod slipping past the switch set-point.<

 I have not heard of any problem either.  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.
