Small footprint switches?

As of lately, I am involved with designing an amateur radio APRS LoRa personal messenger project, with a physical appearance similar to this:

I would like to probe this group for any recommended suggestions for small footprint switches (mechanical or not). Thanks in advance!

The switches in computer mice come to mind, but I’m not aware of any keycaps that work with those. Could go full DIY and 3D print your own keycaps?

Very good first suggestion. No, I do not intend to use any keycaps at all, as this would compromise the reproducibility of the project.

Does this count? https://mechboards.co.uk/products/pockettype
