Duo-Phase Sync / Switch Toggle Order?

[Fingolfen]

I'm working on an enclosure design for my Duo-Phase and want to make sure I get the order of the switches correct for the labeling:

SW1 controls LFO

I just realized how incredibly confusing the description of these switches is....

The top switch selects which LFO controls Phasor B. Up = LFO A, Down = LFO B.

The bottom switch inverts the phase of Phasor B. Up = Inverted, Down = Not inverted

So... like this?

 

[Robert]

Yep, that looks correct.

So A is left and B is right? And which one is first in the chain?

I think side B is first in the chain!

 

[giovanni]

I think side B is first in the chain!

OK thanks! That makes sense!

I am working on a laser-cut faceplate for my build, here's the idea:


I like the idea of using the LFO/signal path as part of the graphics design, especially since the faceplate is monochromatic so I can't introduce color, but I can use shapes.

 

[Robert]

Yes, Side B > Side A.

FWIW, when an ambiguous description is presented for switches, pots, etc in a build doc, I usually start comparing the parts list and schematic to get a better idea of what was intended and sort things out that way. In this case, I noted that the top tgl switch is a SPDT while the bottom tgl switch is a DPDT. So the toggles kind of identify themselves that way when comparing the BOM to the schematic.

I imagine it's a challenge to present every nuance of a build in the build docs. After all the other elements and bits of information that go into putting a PCB project together. Building is one thing. Building for builders is another ball game altogether.
