WHY are the symbols for power on / off “|” and “◯”?

What are/were they meant to represent? When were they introduced? I can’t find any consistent reliable sources. I’d really appreciate references if anyone has any!

It is early & basic programming language called binary where the number 1 represents power & 0(zero) represents no power. So the symbol for on became 1( one) & off or no power is 0.
