It shows the layout of the super switch. With it being an exposed lever switch, one can easily see the switching just by looking at the switch and cycling it thru its positions.
It's a 4 pole, 5 way switch. This means that each of the poles selects 1 of 5 contacts per position.
While one could use just one pole to realize the cap switching, it may be much easier from a wiring perspective to use two adjacent pole structures. This way, each cap could span the gap (0.5"/12mm) from one wafer to the next between like selected contacts, one pole's common (wiper) would go to the common pickup hot point from all volume controls, and the other pole's common (wiper) would go to circuit ground. In essence, the switch pole commons replace the traditional tone pot/cap connections.
