Finding a Gottlieb score motor switch from its schematic name

Seen from above, the switch stacks are numbered 1 to 4; the angled stack beside the cutout at position 3 1/2 is the reference point (number stickers are often missing). Levels run A to E from the bottom: A below the cam, B worked by pins below the cam, C by the cam itself, D by pins above it, E by tall pins above it. So Motor 1C is stack 1, level C; when that position holds several switches, pick by wire colour. Gottlieb's side-view drawing misleads: the switches actually run at right angles to how it appears.
