I would like to solder a push button directly to the Raspberry Pi Zero's 40 GPIO row (without the header). I am looking for instructions on how to do it and also possibly for a suitable button type/part that will nicely fit to Pi's GPIO hole dimensions. The button has to betall enough so that it could be enclosed in a 3D printed case and still be accessible with a finger from outside the case.
This 10 mm tall Omron type B3F is nice but I think the dimensions of its "legs" are not very compatible with the GPIO row.
Alternatively, I could use Zero WH with header, and solder the button directly to the header. But still a suitable button part is needed.
