OK. Well, if the clicker toys sound like the clickers in the video, then beam-springs and calculators don't really sound that loud.
I also think that a great clicky keyboard switch should only have one sound: the click on actuation, no sound at all on the rebound and the sound on bottoming out being irrelevant ... because you force curve of the switch after actuation would ramp up and thus discourage you from bottoming out, with the bottom very low.
Some clicky keyboard switches click twice: once on actuation and once on the way back up, which I think is crap.
