Questions
How big is the Switch Key PCB?
It measures 19 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Switch Key use?
26 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 Switch Key KiCad files?
From the Ashlaiden/PCB repository on GitHub, at the commit this page was made from: the board is Switch-Key/Switch-Key.kicad_pcb and its schematic Relay/Relay.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switch Key design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
