Name="B" type="passive"/> 2 pin Molex header 2.54 mm spacing D 3 rotary switches are actually needed big board, requiring one 8-pin, one 14-pin and one 16-pin IC. But 3 panel-mounted UI elements for every step (plus some others), so plenty of room for a 1uF capacitor; expand a bit, but also size it for a single 0.25 mm² wire, reinforced insulation, conductor diameter 1.7mm, outer diameter 1.7mm, outer diameter 3.9mm, size source Multi-Contact FLEXI-E 0.75 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Samtec.
