So now I am making my switches for my car. My first switch I had to cut out to pieces of cardboard and glue them together. The way all of the switches work is 2 pieces of tinfoil has to touch. My second switch is a straw with tinfoil. You have to push the straw though a hole to touch the other tinfoil. My last switch is a popsicle stick that spins and at a certain point it touches other tinfoil. The tools I used were a jigsaw, hot glue gun, masking tape and tinfoil. The hardest to make was the last one.
