What kind of buttons for menu?

Hi, I was wondering what type of button is recommended for the menu in the minimal build for the SID. I assume these are momentary button switches correct? How do these look:

What do they mean by tactile? Maybe they are too small?

those are surface mount tacts, so you don’t want those ones, plus you probably want ones with a bit of a stalk on them so you can put keycaps on then.

tacts means you feel a click when you press it, your mobile phone probably has them on the menu keys and on the send and end call buttons.

have a look through the forums, there is more info on buttons than you can poke a stick at
