Z heights between base and panel:

- 60mm slider - 7mm, with 3-4mm extra space available
- mini toggle switch - 9.5mm, +5mm extra space
- micro toggle switch - 7mm, +4mm extra
- pushbutton panel mounts - 8.6mm, +4mm extra
- thunkicons - 8.9mm, +3.5mm, make sure to use 7.5mm holes, not 6mm
- alpha pots - 9.8mm, +2mm
- rotary - 11.5mm, +3.5mm  -- biggest by far, maybe 12.6mm?

- other rotaries:
SR2511 series are 11.43?  Maybe more?



Distance between pcb and front panel:
9.8mm (alpha pots)

sliders: ~3mm a
mini toggle: ample space above pcb
micro toggle: probably too short without extra spacers, use mini toggle
pushbuttons: ample space above


11.75mm (existing 1p12t rotaries, use 11.25mm holes to minimize distance)
+1.6mm (pcb) = 13.35mm
sliders: 2mm above panel (cutting it very close, would need to glue knobs)
thunkicons: tight, but could work with printed spacers
mini toggle: 2.5mm above panel, tight but possible
micro toggle: 0mm above panel; could work with spacer but it will be very tight
pushbuttons: just enough for nut, but could also use a non-metal spacer underneath
alpha pots: tight, only 1/2 turn for nut



11mm - rotary, SR2511 style, with very large 17.5mm panel hole+snip off pin, add holes for the four plastic clips
+1.6mm (pcb) = 12.75mm

sliders: 3mm above panel, tight but possible
mini toggle: 4mm above panel, ample
thunkicons: probably too tight; could work with printed spacers and existing lead lengths
alpha pots: barely enough to attach knob
