README
readme.mdMicroswitch PCB
As part of the Smallpeice summer school, students create sensors to mount on their robots. Previously, this has been done using breadboards and veroboard. This suffered from issues with fitting the microswitch pins into the breadboards and mounting the board to the robot.
As such, this PCB is designed to be a simple breakout board for a microswitch. It has footprints for a microswitch, debouncing circuitry and a 3-pin screw terminal to connect to the board. The board is designed to be mounted on 2020 aluminium extrusion chassis with M5 screws.
Components
- Right-angle microswitch: C504864
- Screw terminal block: C5188435

Questions
How big is the Switch pcb PCB?
It measures 50 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Switch pcb use?
9 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 pcb KiCad files?
From the sourcebots/microswitch-hw repository on GitHub, at the commit this page was made from: the board is switch_pcb.kicad_pcb and its schematic switch_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switch pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask sourcebots before reusing the design.
