yoko1 said in answer to my awkward query
When you refer to the "removal of the yoke/stick switch," I think you are talking about the control column cutout switches that prevent trimming in the opposite direction that the control column is displaced (that is, stops nose down trim when pulling back, stops nose up trim when pushing forward). This feature has not been removed and still functions as designed except that these switches are bypassed for MCAS activation (and only for MCAS activation).
It was my understanding that the installation/addition of MCAS software AND the wiring change shown in peter lemmes blog resulted in the disconnect of the control column cutout switch-. Thus the change from NG wherein at anytime the pilot pushed or pulled in opposition to the stabilizer trim, the electric motor stabilizer trim was shutoff leaving only elevator? and manual trim wheel and ? .
Apologies if I've totally botched this up ;((
