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!

Everything runs on binary. Which is a series of 0 and 1s. 1 signifies it’s letting an electric signal pass through it. 0 means it isn’t. So, 0 means OFF and 1 (|) means ON.
