Kcs low power electrical push push switch

thingiverse

This low power electrical switch is an integral part of my reading lamp design. My primary objectives include designing a completely printable switch (excluding cables, electronics, and wiring) that's effortless to assemble and print without excessive overhangs. The switch mechanism is inspired by push-push mechanisms found in ballpoint pens. After weeks of experimentation, I came up with a design that works but is only suitable for low power applications like LED lighting. However, during recent testing, the big spring deformed permanently after prolonged activation and rendered the switch inoperable. Consequently, I am working on refining the design by possibly increasing the space and using longer springs or exploring alternative options. To assemble the switch, print each of the STL files once with a 0.2 mm layer height and 0.55 mm extrusion width using a 0.5mm nozzle. It's advisable to print the two springs separately due to adhesion issues. Clean the pin and tracks on the labyrinth part for smooth movement. Align the pin, attach the spring box, insert the small and big springs, place the separator, attach the top lid, and enjoy using your switch!
