It's not electricity, exactly, but it is a higher voltage that is different from the average of everything around it. Electricity needs a closed loop to flow, and breaking open the loop with a switch means that no electricity flows, but the voltage of the live line goes up and down, creating an electric potential with anything that might be at a different voltage, if a conductor touches both.
