This invention relates to a plug socket that supplies or automatically cuts off power by determining the operating states of plural electronic devices connected thereto and changes the setup for power cut-off according to setup mode. Therefore, the plug socket can cut off power completely when an electronic device is not used to conserve energy and prevent an electrical accident. In a home network system, in particular, the plug socket supplies power to an electronic device only when the electronic device is used. Thereby, the unnecessary power consumption in a communication standby state can be remarkably reduced through the efficient use of electricity and the electrical cost can be saved. Furthermore, even in a built-in type plug socket whose location is fixed, the user can control the timing mode and method of power supply and/or cut-off according to the electronic device or the user's needs. Therefore, user convenience can be remarkably improved. |
