which kind of buttons?

hello ,i 've found an old stock with some buttons but some are “momentary push button " , other are " toggle switch” and other “push on - push off switch” .

i’ve some 3 positions toglle switch too , can i use all of them together ,how to tell to mios how react buttons?

i’ ve some 100k pots ,can i use them ,instead of 10 k pots?

Hi, for (most of the) buttons used in MIOS applications you need momentary pushbuttons wich are “normally open” (=NO); the switch will only be closed when you push it. Push on/push of can be used for power switch.

Keep the 3 position switch for other projects (lp/bp/hp switch on a nice diy vcf for instance :))

as for the pots; a few posts down you can find this;

good luck, marcel

“normaly open” :that’s means i must have 0 volt when the button is pressed and released or just when the button is pushed?

Normally open means that the pins on the button aren’t connected together until you push the button.
