I was feeling cheep and did not want to buy a switch so i designed and printed one. Now i can make as many as i need. Also no solder required just wire and a 3d printer..
Print all parts. Cut some small wire 12 inches and coil it around the inner switch. After that loop the some wire around the holes in the outer switch . place the inner switch in the outer switch. test then close with the switch cover and melt the two tabs to hold it together.
