The prototype had a single 8-way DIP switch. This was fine if you only wanted to use one character. In Battlefield V you can play as 4 different classes, Assault, Medic, Support and Recon. I thought it would be a good idea to have a DIP Switch for each of those so you could customise the action that each one actioned on the footswitch press. I added a 4 way rotary switch to the circuit and designed a PCB around it. I am currently waiting for them to arrive. Once proved, I will add the construction files, gerbers and schematic along with the code to this page.
