Which is the on/off position on a switch?

Is the "O" on or off, and is the "-" on or off? I have an electric scooter and don't know which is the on position. Thanks.

O is off
I on on

Up us usually on
down is usually off.

From what you worte

O would mean on and

would seem like off to me because it looks like a face with eyes closed as in sleeping.

usually in the up position is on, if thats where the o is it means on.
