why not invest in a cheap jigsaw? should be able to get a good result with that. i picked a cheap one up from Wickes(uk) for about £25 5 years ago, its had a tough life and still going well
this is true. while you cannot detect multiple presses, this would be a nice easy solution for a rotary switch. as has been said, multiple presses would give some strange results. if you thought about it, you may be able to make some kind of a puzzle game, where multiple presses are required! good luck.
