Jim,
  The latch action was the part that I was not sure of--thanks for the update-Ron Rich

  The selector button on the H100 I just worked on did not mechanically latch 
anything - it just energized the sprag relay coil. This sprag relay did have 
a long armature that must travel all the way down into a notch in the "sprag 
wheel". The sprag wheel is connected by gears to the selector wheel and the 
pin pusher assembly. The sprag wheel is detented with magnets and must be 
adjusted so that the notch is top dead center while at the same time the pin 
pusher is properly positioned. This detent helps with any "slop" in the 
selector wheel. This system is much easier to work on than the electrical 
selectors.
