My ‘52 3100 headlight switch has three screws on a connected terminal block, where the switch is supplied with power. Since the turn signal switch is located near the headlight switch, I used one of those terminals to supply the fused turn signal supply. I looked at the switch for a ‘41-‘46, and it appears to also have those same three screws, although a totally different switch. I could be wrong, but it is something you can look for.
