Mod Osc board uses a different kind of rotary switch and potentiometer #16

Most of the boards use alpha SR1712F style rotary switches and alpha RD901F style potentiometers.

The Mod Osc has a 5 position waveform rotary switch. The SR1712F switches don't come in a 5 throw version, so I used an alpha SR2612F style switch instead. Since this kind of switch is taller, I needed to use different potentiometers as well. I used P260T style pots here.

I would prefer it if all the pots and switches were from the same family. The Mod Osc pots and switches have a different amount of mechanical resistance when you turn them compared to all the other boards, and it inflates the BOM.

There are main 2 choices here:

There are a bunch of short rotary switches floating around on aliexpress and similar sites, going under the name SR16 or RS16, maybe this kind of switch would work? I would prefer a name-brand switch that you can get from a standard distributor, but these might work ok.

Investigate a little and think on it.
