DISCLAIMERS
This is still "work-in-progress (WIP)" so I do NOT take any kind of responsibility for damages/data losses!
You can use this at your own risk without guarantees and put device on non conductive surface or enclosure!
If you like the new design yo are free to share it!
Have fun :)

Questions
How big is the TR Switch PCB?
It measures 50 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TR Switch use?
22 parts. 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 TR Switch KiCad files?
From the wodowiesel/TR-Switch repository on GitHub, at the commit this page was made from: the board is TR-Switch.kicad_pcb and its schematic TR-Switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TR Switch design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
