 When I do my micro switches/position switches for flaps, gear, etc.,  I
 want to experiment with hall effect switches.  Their orientation
 apparently affects their accuracy.  I have not experimented with them
 yet, but plan on building a bench setup with them to see how they might
 work.
 
 They should avoid the mechanical problems of your switch, but it's the
 accuracy aspect of them that I don't know anything about however....
 
 Thanks

  Each time that I have experienced this problem I have replaced the
 limit
 switch with a new one.  I even carry spares along with the tools it
 takes to
 get to the assembly in case I have the problem away from home (which has
 been
 the case two of the three times it has happened).
