Replacing Tactile Buttons

Post by bfesser » Fri Jul 03, 2020 5:43 pm

I searched the forum posts on this product and also checked GitHub, but have been unable to find any reference to what tactile switches are used on this board. I'd like to desolder the existing switches, and replace them with shorter ones--less prone to breaking. Does anyone have a part number for the ones used on the board (V2.0)?

It probably depends on where and how the board was made - lots of versions around in both surface mount and through hole designs. All you need to do is match the footprint on the PCB. There are plenty of similar switches available. Something like this might fit; they are very common and are available with various length actuators.

Thank you for the reply and link, Brissieboy. They're surface mount. I work as an apprentice moldmaker, so I suppose I could de-solder the switches and measure the pads under a toolmaker's microscope at work.
