Tact switches with low actuation force
deʃhipu wrote 11/10/2019 at 04:14 • 1 pointAnybody has any ideas about where to look for tact switches? I'm specifically looking for sourcing 6x6x6mm switches with as low actuation force as possible (preferably below 100gf), but most part catalogs out there (digikey, mouser, lcsc, tme, etc.) don't really have that many switches in stock, and some don't even include actuation force as a parameter.

Are you sure? yes | no
have you look into conductive buttons
Are you sure? yes | no
Worth looking at the alps web site too. Some of those are down to 3N or so force
Are you sure? yes | no
thanks, I checked it, but it seems like they only have some weird footprints for those, not the standard 6x6
Are you sure? yes | no
RS Components seems to let you filter by actuation force. There are a few Alps parts on the UK site.
Are you sure? yes | no
Thanks, sadly they only have two switches that are 6x6mm and higher than 5mm, and they are both the standard 160gf.
Are you sure? yes | no
Can you add something to make up for the height difference in shorter buttons?
Are you sure? yes | no
Well, I'm already adding something, a laser-cut d-pad, but it needs some space to attach to the button: https://hackaday.io/project/165032-pewpew-m4/log/170390-laser-cut-buttons-done
I will be experimenting with some other solutions as well, so this is not critical. I just found that the tiny SKRP buttons also come in a low-force version, so I will experiment with those.
