Ok here is a step by step on making the circuit board and wrapping the wire.
I have reduced the size of the circuit board to 2 wide by 4 holes long. Insert the wire so it looks like so:
Pull the wire tight and straight up as such:
Now twist the wire so you have wires pointing from both sides and so:
Now solder, you can trim this to fit exactly in the hole of the battery connector and the RCA center post, so you don’t need a centering spring. Build up the solder at the Y to make better contact with the battery or RCA connector:
Don’t forget to solder on the switch and test it before you put in inside:
It helps to make an isert to protect the ciruit from grounding, here is an idea I had:
Well hope this helps clarify things,
