So I'm adding a couple of slide switches to my Duo. One to split my bucker and one to knock the pups out of phase. I figured if I'm putting two on I might as well use a Jag switch plate for cool factor.
It would looks something like this:

Now my question is if switch 1 is coils split and switch 3 is out of phase... what do I make switch 2? Just leave it as a dummy switch (no purpose)? A kill switch maybe (I have no idea how to wire a kill switch)?
Any advice is appreciated. Or if you think I should just install the switches without plate and leave them be, let me know.
