Power-controllable outlet receptacle

An intermediate type power strip comprising:

• a plurality of intermediate socket main bodies inserted into sockets and respectively including at least one connecting socket;
• a remote controller to individually control the plural intermediate socket main bodies in remote through a radio frequency communication;
• wherein respective surfaces of the intermediate socket main bodies are distinguished by indicators;
• wherein the remote controller comprises:
• socket controlling buttons respectively corresponding to the plural intermediate socket main bodies;
• light emitting lamps respectively corresponding to the socket controlling buttons;
• and
• an electric circuit;
• wherein the electric circuit comprises:
• a memory to store allocation index codes with respect to the respective intermediate socket main bodies;
• a keypad including a lamp button to check statuses of the socket controlling buttons and respective switches installed in the respective intermediate socket main bodies to generate key data corresponding to a button that is pressed;
• a radio frequency transmitting and receiving unit to perform a radio frequency communication with the intermediate socket main bodies;
• and
• a remote controller controlling unit to request to check the status of the switches to the intermediate socket main bodies through the radio frequency transmitting and receiving unit when the key data corresponding to the lamp button is inputted from the keypad, to control the light emitting lamps to be turned on or off according to a response for the request to check the statuses of the switches when the response for the request to check the statuses of the switches is received from the intermediate socket main bodies, and to transmit a switch remote controlling signal to a corresponding intermediate socket main body among the intermediate socket main bodies through the radio frequency transmitting and receiving unit via a wireless line when the key data corresponding to the socket controlling button is inputted.
