9 parts, built around the OSTVN04A150. 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.
From the mwbrown/buttonbox repository on GitHub, at the commit this page was made from: the board is kicad/button_mount/button_mount.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
