PURPOSE: An electronic time switch is provided to supply or cut off power automatically at a desired time by controlling a remote controller. CONSTITUTION: According to a power measurement system, a power meter(10) measures power consumption, and a converter(20) converts a voltage by being connected to the power meter, and a magnet switch(40) performs a switching operation to supply or cut off power by being connected to the power meter. A time output unit(30) is connected to the converter and displays time to control power consumption time. And a remote controller(50) outputs a time to supply or cut off power to the time output unit by operating a constant radio signal.
