Switch types

[Mugician]

What kind of mini toggle should I use to coil tap ONE humbucker? Still DPDT or will SPDT work? Also: on-on, or on-off for coil tapping?

You only need a SPST switch.

But if you get a DPDT, ON-ON-ON switch, you can have the switch be series/single coil/parallel. Much more versatile.

Either on/on or on/off will work.  Any DPDT or SPST or combination thereof will work.
