Abstract
In one example, an electric circuit may be provided that is coupled to a line. The electric circuit may include a switch connected in series with a load, where the switch and the load are in series between two conductors of the line. The line may provide power to the load. The electric circuit may also include a resistive element connected in parallel with the switch and in series with the load. The switch may be configured to short circuit the resistive element when closed such that the voltage on the line varies between two voltage levels when the switch is opened and closed. The line provides power to the load when the switch is opened and when the switch is closed.
