I was brooding over "Make-and-Make-Switches" and "Make-and-Brake-Switches" and stumbled over a crummy drawing in the (ipdb) schematics "Space Mission".
The first JPG is self-explaining - Make-and-Brake-Switches are of "either - or" functionality --- or then they are "an N.O.-Switch and an N.C-Switch mounted as an threebladed switch (very often on the Score-Motor)". Also known are references: "To wire-this-color".
Studying the Space Mission schematics I have seen an CRUMMY drawing - see the second JPG: I would like to see the "good" part and the "AA" part - BUT Williams did: "Good" part and the "BB" part - means: The BRAKE-Part of motor-5B IS DRAWN TWICE --- and there is also the reference "To R-BR" - hard to understand such crummy schematics (look it up in the ipdb-schematics).
