The MR0102 toggle on the right has a support bracket with 4 pins. I can easily ground those.

The SR25 SP4T on the left has no such pins.

I suppose I could pass an eyelet connector over the shaft and fix with a nut and then ground the wire to the PCB mounting screws. I have about 1cm of room under the knob; more than plenty for the plastic enclosure.

That will be a concern on the RV17 rotary pot; the shaft is short and I don't have much thread space. :/
