I have taken switches like that apart and all have had an arm with contacts on both sides goes back and forth, to and fro, with the movement of the bat handle. Not being able to be two places at the same time... You get the picture.

That said, if you took a low current fuse, say 1/10 or 1/100 amp job and connected a battery post through the fuse and to one of the outside terminals of the switch, then the other outside terminal of the switch back to the other post of the battery.

Now flipped the switch back and forth, how many times, pick a number, 1, 10 or 100, the fuse will still be good. Two possibilities. One, its break before make. Two, the switch never makes long enough to blow the fuse but that I think is unlikely. The make before break would never be long enough to do any good, so what would be the use.

Good luck and don't burn the house down,
Mike
