I wired up the switches for a second 1x4 keywell column yesterday. I approached the different wire lengths by just soldering the loose ends at whatever their current length was. This messed up the arrangement and I think the only way to fix it is to remove the dupont connector, cut all the wires so they end at the same spot, recrimp the dupont ends and re-attach the dupont housing. I think trying to pre-build these wires while on vacation didn't quite work out. But that should be pretty straight forward.

I've also been frustrated with so little clearance between the switch pin and the printed housing, so as I proceed I plan to solder a longer bit of wire to the switch pins BEFORE I glue the switches in place so the hand wiring should be less fiddly and tedious.
