Anyone got any wiring diagrams for an ON/ON miniswitch? I wanna basically set it up as a killswitch but im not sure how to wire it.

Heres the best pic I can find of the one Ive got. It has 6 connection points on the bottom.

The killswitch thread should have an answer, but you take the hot wire that goes to the jack, and solder it to the middle lug. Then solder one of the outer lugs to the tip of the jack (where the hot output usually goes), and the other to a grounded point (sleeve of the jack/back of pot/whatever).
You don't need the other 3 lugs....
