For my switch project, I design a little punching machine. Unfortunately, you still need to use your finger to control it, but the way you trigger it is definitely more intriguing than just press the original switch button. As you might have already noticed, there is a seesaw at the bottom. In order to trigger the switch, all you have to do is try to shoot the disk, rolling in the middle, to the top and be attached by the magnet. For the conductive method, I have use aluminum foil, paper clip, and also some conductible wire. It might seems difficult to reach the top at once, but practice makes perfect. However, this also makes the switch not convenient enough to be used. So my next step would be thinking about how to make the chance of hitting and attaching at the top more easily.
