I've got one of them here (early 126 type 3 wheel) and it is a PC board with a pot on it and some traces in an arc. The wheel has metal fingers that short out the traces at the two ends of travel. Here's what I can figure out looking at it, it has 7 pin sockets, I'll number them (looking into the sockets) : 1 2 3 4 5 6 7 The pot is connected so that the "Min" end of the element is on pin 7, the "Max" end on 2 and the wiper on 3. When the wheel is at "Max", it shorts 5 and 6. At "Min" it shorts 1,5 and 7. Anywhere else in its travel, the wheel shorts 4 and 5. HTH (clear as mud right?)
