Questions
What parts does the AUX switch use?
25 parts, built around the BC337 and HRS2H-S-DC5V-N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the AUX switch KiCad files?
From the Maltheren/AUX_switch repository on GitHub, at the commit this page was made from: the board is AUXswitch/AUXswitch.kicad_pcb and its schematic AUXswitch/AUXswitch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AUX switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask Maltheren before reusing the design.
