This is easy. What you want is either the front coil, the back coil, or both coils in series or parallel, right? This means you need a single FOUR-way switch, like the 4-way Telecaster blade switch. If you want the last additional choice, which is both coils out of phase with each other, you need to hook up a 5-way "Superswitch." I did that on my first one, but in practice I found it to be useless to me. You would need two 4-ways for a two-humbucker guitar - that and a 3-way to choose between pickups and a concentric tone/volume pot for each pickup gives you a hugely diverse-sounding guitar, but quite easy to manage on stage. There are rotary switches that duplicate the functions of the blades too. But you can never get four functions out of a three-way switch, so you're stuck with blade or rotary switches. And then just use the diagram for wiring a Telecaster 4-way, but each coil is treated as a pickup. If my brain is working right here (NOT guaranteed) you'd need THREE mini-switches per pickup to duplicate this with those alone.
