All of us has been seeing this icon in all our electric and electronic appliances, but do you know where does this symbol come from?
It is pretty simple. It is a combination of “I” and “O”. In electronics, people use “O”(zero) to denote an off state and “I”(one) to denote on state of any appliance. So a button/icon with the power symbol indicates that the button can be used to change the state of the appliance from on to off or vice versa.
