Making a PCB to use ITW switches with Arduino atmega?
« on: Fri, 20 July 2018, 17:50:25 »
Is this possible? I vaguely understand how the ITW magnetic switches I have work.

A switch is just a method of connecting two pins on a controller chip which doesn't know what type of switch was used or if it was just a bit of wire, all it knows is that the connection has been made - this means you can use any switch you want.

Depending how the switches work physically you may have problems with chatter which would be the only thing that could make a keyboard unusable.  There are debounce settings in existing keyboard firmwares which may or may not be good enough - you're the 'expert' on these switches so wire one up without a PCB and see what Aqua Key Test makes of it :)
