Now I am imagining a typewriter with just two huge round buttons, next to each other horizontally, and a spacebar bellow them:
reply *-----* *-----*
| | | |
| ● | | Ω |

*-----* *-----*
[================]
Now remove the spacebar, combine the two buttons into a single one for "tone" and adapt it to morse code. All the buttons still do only one thing and now there's only one button!
replyAnd, you don't have to worry about what to do in the case that someone hits the "rotate ball" button while it's still rotating.

replyEh, it's a pretty trivial problem, comptometers have it figured out more than a hundred years ago.
Apple still did it best: https://www.youtube.com/watch?v=9BnLbv6QYcA
replyThe power button of my pc also has the job to tell wether the PC is turned on. So do bulb switch buttons that have a pilot light, and so on
replyYeah, sometimes, when I am sitting before my computer and typing comments on the Internet, I have a thought: "Is my computer turned on?" With a quick glance under my table I can reassure myself that it is indeed on and continue using it. No idea what I'd do without that small blue LED.
replyThe pilot lights are slightly more useful in those stupid cross-wired double switches that for some weird reason implement a sort of XOR (or sometimes XNOR because why not) gate for controlling a single light: if it's on, then the bulb is depowered and you can safely change it without turning off the entire power rail. But then one day the pilot light itself burns out...
You can safely change a bulb in a socket that is powered on. Just don't stick anything else in it but the bulb.
