How to connect the Turbo board + 2x Super SC (drawing, post #15) **revised

[MiamiBoy]

Okay I'll try AliExpress.. thanks!
I meant minimum 7 steps, because that's the minimum I need, so 8 would be good, 10 or 12 also fine..

Unfortunately I can't read/understand the schematic, so that's not an option.

I have one pushbutton for Turbo off/on and one for bypass off/on.
SCC filter would be a rotary switch for off/filter

Maybe take a look at AliExpress. They have some unusual rotaries there, but need to fit into case.

If you had to guess, how many poles, decks & positions does this one have? (the page says 2 pol 11 pos)
Their product descriptions on AliX isn't always sufficient

That's the only option
