Microswitch (without lever) by ProgressTH

Last crawled date: 4 years, 7 months ago
This is an opensource 3D printed microswitch, the first in a series of common electronic components we are developing to share for people who want to download and print out components faster than they could go to the store and buy them, or order them and have them delivered.

WARNING!!!! We are still testing this, and so be very careful if you try to use this. Use for experiments only, and err with the expectation that it will fail or even catch on fire. Don't integrate it in with your brand new 3D printer, or leave it going 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 perfect) 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 are an electrical engineering expert and spot obvious flaws or safety issues, please comment!
