Hardly intuitive, is it. In what parlance/language does "1" stand for "on?" Binary? On an A/C line power switch? And, if it was meant to be a zero, it should have had the slant bar thru it, like '0', to avoid just this sort of ambiguity. Hmmm. The electrical symbol for current is 'I'... Anyhow, it is a curiosity! Most ordinary humans do not think in terms of binary symbols when it comes to ordinary, everyday items like hardware power switches. My wall switches, even the toggle or rocker ones, do not have 1 and 0, or even I and O on them. keith
