Overview
AccessibleSwitches is an open-source printed circuit board by greenpanda111, from the greenpanda111/Accessible-Switch repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board with 4 parts on 2 nets, routed with 8 tracks and 0 vias.
It is built around the D2FS-F-N. Its parts include 2 capacitors, 1 connector and 1 switch.
Main components

README.mdAccessible-Switch
Accessible switches allow people with disabilities to interact with toys, games, or other technologies. They come in many different shapes, sizes, styles, and actuation forces. Each person has their unique switch configuration that best allows them to have maximum freedom. However, these switches can cost as low as £30 for a single, basic switch. This repository aims to improve access to a basic variety of switch for families and charities.
The switch is assembled from three 3D printed parts, a custom PCB, a microswitch, a 3.5mm mono jack cable, and three springs.
PCB
PCBs can be ordered through JLCPCB with default parameters. Simply download the gerbers.rar file and upload it to JLCPCB. The PCBs only require three pins soldering for the microswitch, and the two mono jack wires. Polarity of the wires does not matter, but when soldering the microswitch, the plunger should be closest to the white circle on the silkscreen. This should be accomplishable by someone with minimal soldering experience. The PCBs also have debouncing capacitor support, but these are not neccessary. A 100uA capacitor would be suitable, however.

Future Improvements:
- Redesign the PCB mounting in the base so that it has a snap-fit connection so screws are not needed. This would allow the base to be even slimmer
- Version 2.0 where there is no locking ring and the plunger can reach the edge of the base

Questions
What parts does the AccessibleSwitches use?
4 parts, built around the D2FS-F-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 AccessibleSwitches KiCad files?
From the greenpanda111/Accessible-Switch repository on GitHub, at the commit this page was made from: the board is AccessibleSwitches Kicad/AccessibleSwitches.kicad_pcb and its schematic AccessibleSwitches Kicad/AccessibleSwitches.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AccessibleSwitches design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
