I am looking for the origin of the power symbols
0 (off) and 1 (on).
The earliest standards that I have are CEE 10
and similar where the standard specifies something
like:
"Where a rotary switch is used for power,
the 0 position shall be off and the 1 and
higher position shall be on."
Do you have the specific wording? Do you have
something earlier than the CEE standards?
Thanks for your help!
