I have re-assembled my 1961 10ee with the ELSR after cleaning out all the old krud.
Everythig works smoothly including the ELSR mechanism. Now I am trying to
adjust the switched in the ELSR housing to the left. It is pretty obvious how
they should be adjusted.

I have a problem with the top Microswitch. The plunger on the switch it pressed
when the control lever (on the apron) is in the middle (off) position. If the
lever is moved up or down the plunger is released. I can adjust the switch
to operate properly but often the lever needs to be jiggled in the center
position for the switch to close properly. The adjusting set screw has a
very narrow range where it works.

If I take the Microswitch out and test it, it works perfectly. It is
Microswitch model DT-2R-A7 and is $144 from Newark Electronics, OUCH!
I would rather not buy a new one.

Is there any trick to getting this adjusted correctly?

I was able to adjust the other 2 switches without any problems.
