standard drills for switches and sockets too loose.

[Eszett]

Hi! The drill holes for switches are 4mm by default. But 'm not quite satisfied, my Kailh switches fit in quite loose, I'd rather prefer snug fit. What value would support a snug fit?

You should use calipers for your measurment, and maybe switch to pcb switch footprint instead.

If you make holes snug, some switches would not put inside because of manufacturing accuracy.

When it gets down to that level in an experiment, I usually go to trial-and-error until I find the best answer.

Sometimes an Imperial measurement tool will give you a good increment between mm or half-mm choices, for example 9/64" or 5/32" are between 3.5mm and 4mm.

if you are getting kits and the holes feels too loose, maybe you can try some silicon tape (use for plumbing) on the ends of the switches before pushing them in. other tapes might work as well.
