Pull Cord Kill Switch
thingiverse
This is a proof-of-concept pull-cord kill switch design, modeled after the ones found on boats and jet skis. A limit switch is installed within the box, which closes when the key is inserted and opens when it's pulled out. This concept was initially designed for my DIY self-balancing scooter project. It's still a work in progress, so I strongly advise against using it as a safety device. Use at your own risk!
