[IxDA Discuss] This is the ultimate power switch WAS: Power icon

[Charles B. Kreitzberg]

I like the idea of using illumination as a secondary clue.

In English, of course, both on and off start with the letter "o" and some
users are confused by the standard 1 and 0, thinking that the zero is the
letter oh (+on).

I suspect that the origin of the 0 is that there is zero power in the
circuit when the switch is on but I don't have any documentation about that.
