I am looking for some advice on choosing a rotary selector switch to switch between the three output impedances options for a pair of Sowter 8665 headphone output transformers. The circuits for the three configurations of three secondaries for each channel look like this:

Does it matter if I go with 6 poles x 2 decks, or is 1 deck with 12 poles functionaly identical? I believe the switch should be 3 (or more) way. Any thoughts, or advice as to which switches would be ideal will be gratefully received.
