Push Button Breakout Button
A breakout board for 12mm or 4.3mm tactile push buttons to be connected to a micro controller for learning environments.
The breakout features both 2.54mm and 3.5mm connections for either male or female pin headers or 3.5mm screw terminals.
Now includes a normalised and simplified Fritzing version of the part (with just the 2.54mm pads) and an Illustrator (AI) and Inkscape (SVG) file for preparing slides.
Originally designed by Tom Lynch for the Creative Technology Lab at London College of Communication, version 2 updated for UAL: Creative Computing Institute.

Questions
How big is the Button breakout PCB?
It measures 17.4 × 19.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Button breakout use?
6 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 Button breakout KiCad files?
From the ual-cci/push-button repository on GitHub, at the commit this page was made from: the board is KiCad/button breakout.kicad_pcb and its schematic KiCad/button breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Button breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask ual-cci before reusing the design.
