Installing a coil tap switch on my guitar. Just going to use a SPDT micro toggle. I dug up the diagram below but trying to get my head around it. Currently South and North finish wires joined together. I assume the middle lug is common and the switch selects 1 or 2. I can see where in position 1 it leaves the North / South finish wires still joined but isolated so will get the full HB effect. But I can't get my head around the number 2 position? It looks like the circuit will have a path through the South coil to the output, but also a path through both coils as well through the North Start cable to out put? What's happening here? Does it simply take the path least resistance from South finish straight to output rather than going through the North coil? Does the circuit look correct?
