Microswitch (without lever)

cults3d

This is a free 3D printed microswitch, the first in a series of common electronic components we're creating to share with people who want to quickly download and print out components rather than buying them in stores or ordering them for delivery. Follow our projects on Hackaday IO here: https://hackaday.io/project/9942-opensource-3d-printed-electronic-components WARNING!!! We're still testing this, so be extremely careful if you try to use it. Use it only for experiments, and assume that it will fail or even catch fire. Don't integrate it with your brand new 3D printer, or leave it running on a project overnight. Manufactured microswitches are designed for up to a million reliable cycles. Ours is totally unknown. The microswitch requires 1mm steel wire to create the contacts and a 5mm dowel of some sort (disposable chopsticks work perfectly) to wind the steel wire around to create the spring mechanism. We'll do an Instructable once this is tested and refined. But for those who are curious and have 10-15 minutes to print it out and another 10-20 minutes to fiddle with it, you can give this a try. The SketchUp file is included, so feel free to customize and improve it! If you're an electrical engineering expert and spot obvious flaws or safety issues, please comment!
