  • Patent number: 7504745
    Abstract: Disclosed is a multifunctional multi-tap (concent) of intercepting a stand-by electric power and a control method employing the same which prevent big fire generated by leakage current by performing an interlocking control and a single-acting control (separate control) in accordance with subordination of respective appliances using a illumination sensor or a body-detecting sensor. The multifunctional multi-tap (concent) detects a signal according, to an illuminance and a motion of body around respective lead-in holes activated as an interlocking control and a single-acting control using an illumination sensor or a body-detecting sensor, discriminates the detected signal by a controller, and controls the respective appliances as a stand-by state or a power-saving state in accordance with the interlocking control or the single-acting control.
