No greater compliment than to create inspiration. It's what put me on the path, so thank you!

Push buttons are Wellbuying (Well Buying?) ML series. Not the easiest to source since Rapid and Mouser stopped selling 4 pole. :/

PM sent.

Many thanks for the datasheet. I had forgotten you are using illuminated buttons. Not sure if I want to go that way right now but definitely a good way to see at a glance what buttons are pressed and I now have a utility supply on the backplane so it is a definite possibility.

 I see you have squeezed quite a few into your module. How far apart are they?

Cheers

Hey Abby. I looked up Alps SUN and only found non-illuminated. Interested in what you've seen.
That's correct. Console mfgrs that use them have light-conducting knobs custom-made. :(

There was a thread here about this a wile back. I tried to find it but it remains elusive.

OK and the caps are about 6mm diameter? so there is a decent gap between them. I was thinking of about 12.5mm spacing so looks like that is possible.

Yes, caps in photo are roughly 6mm. CAD shows the WB brand clear caps which are roughly 8.5mm .

That is pretty big. What size clearance holes do they need?

Not entirely sure at the moment as they widen slightly at the base to about 8.6 so the hole ought to be 8.75mm Perhaps add another 0.05 to ensure faceplates can be slightly adjusted without cap rub. I can break out the micrometer later tonight.

I have found it all too  is easy for there to be slight differences in the alignment of adjacent push buttons due to slop in the PCB holes when soldered in. This small angular error,  magnified by the length of the switch snout, can easily cause a switch cap to rub on the side of its front panel hole. I don't rememeber the exact number but I think I ened up leaving something like 0.5mm all the way round to accommodate it. With the number of buttons you have, maybe some sort of jig is in order to holes the switches in the right place while they are soldered in.

Yessr. The WB's come slightly crimped every other pin to keep it in place when flipping around to solder. I imagine it also centers them a bit.

That is good. The ALPs ones I used on the EZTubeMixer design had straight legs.. Not so good. I think the slightly crimped legs are called snap-fit.

Lil' update, nothing special. Trudging through necessary terminations of panpots. 22 to go  :'(

Moderators, if you want to move this outside of drawing board, into mixers/monitoring systems, I'm ok with that.

I would suggest you start a new topic there. Maybe then we could move some posts to the new thread.
