Small issue when tapping the NO switch the circuit runs 171 ma to the 20ma led so poof goes the led. Then tapping the NC switch it sends 1.72 amps, not ma but Amps, through the 20 ma led. So poof again. Even a current limiting resistor wouldn't help as the current levels are so different

And when you push the NO switch it sends under –17 MV!

I think you mean the NC switch and it can't be built or used in real life with real components. Useful circuits can't be built by just throwing any old components together. If it’s just for our own fun that's fabulous, but other users, like students and serious hobbyists, that want to learn with the app will undoubtedly be completely lost. Seems a bit unfair to them doesn't it?
