You need a DPDT (Double Pole Double Throw) switch for each 'bucker you want to wire for S/P selection. You could put both pickups on one 4PDT switch but then you couldn't switch them independantly, and you'd have fewer options. And I've never seen a push-pull pot that had a 4PDT switch built in. It might have to be custom made = very expensive.
