CR2032 Switch

thingiverse

I was working on a cosplay prop commission and I wanted a way to make a simple battery holder/switch for some LEDs. I could not find the type of thing that I wanted so I decided to make it myself. :) This is a combination of momentary switch and battery holder for a CR2032 battery. BOM for non printed parts as follows: 2x M3 x 30mm cap screws 2x 6mm x 18mm springs some blu tack or similar to hold battery in 1 CR2032 battery Some small Wires It is pretty straightforward to assemble. You use the small holes to run some wire though similar to other CR2032 holders. then put the battery in the smaller part with some blu tack. the small part slides into the other part and the springs keep them apart unless you push the smaller part down, at which point the battery makes contact with he bottom wire. You will probably need to sand the smaller part a bit to get it to slide smoothly.
