<p>Provided is a plug socket which determines operation states of a plurality of electrical devices connected to the plug socket to supply or cut off electric power to the electrical devices and selects a method for supplying or cutting off electric power to the electrical devices by setting a desired mode. Thus, it is possible to prevent the waste of energy and electrical accidents by cutting off the electric power when the electrical devices connected to the plug socket are not used. Especially, since the electric power is supplied only when the electrical devices are used in a home network system, it is possible to efficiently use electricity, significantly reduce unnecessary power consumption, and thus the cost is reduced. Moreover, in the case of a built-in plug socket, it is possible to change the time or method for cutting off electric power by setting a desired mode according to the kind of the electrical device, and thus user convenience is significantly improved.</p> |
