[sdiy] Designing control surface, potentiometer heights?

[Jack Jackson]

So I'm designing a control surface (Pots/sliders/switches/front panel). I want everything to be PCB mounted for ease of construction and reliability. A problem I've found is the body of the pot/switch before the shaft/actuator can vary greatly in height. So my rotary switches (Lorlin type) are 20mm or so high in the body, whereas the pots and sliders are only around 7mm. See the link for an illustration in CAD: -  https://flic.kr/p/qhipLE

The only solutions I can think of are to make 'scaffolding' PCBs around the same footprint as the pots/sliders to increase the height of them and bring them in line with the switch, or to mount them on a separate PCB and put holes through for the switches to go through.

Any thoughts?

Best Regards,
