I had a bandswitch wafer erupt in fireworks, and had to remove it from an S-40A and then repair the switch.
It is a little tight to photograph correctly, so I used colored wires each time I removed a connection. I coiled a colored wire around each lead and used the same color wire twisted through the bandswitch connection from which it was removed.
I found that solid copper wire works well. I have 4 pair telephone wire and it is just right, 8 different colors with which to start, and added a few scraps of other colors.
