Update 2025- I've designed a way better printable switch, you can download it from Makerworld: https://makerworld.com/en/models/893490

After a couple days in Sketchup and several iterations, I've designed a (so far) reliable electrical switch that, besides the printable plastic housing, only requires about half of a large office paperclip for the conductive components.

Detailed instructions for assembly (with more pictures) available here: https://www.instructables.com/id/3D-Printed-Electric-Slide-Switch-Using-Only-a-Pape/
