PURPOSE: A plug receptacle has a digital timer therein, and controls a power Supply by using a continuous timer function, a flicker function, on-timer function, and off-timer function according to an operation of the digital timer. CONSTITUTION: A plug receptacle includes a power unit connected to a household main power plug receptacle, and outputting an input voltage and a constant voltage dropped to a predetermined level from the input voltage. A main controller receives a constant voltage applied from the power unit, and a reference clock generated from the reference clock generator, and entirely controls a system according to a predetermined program. A plurality of setting keys are connected to the main controller, are driven by the constant voltage, sets each function from the user. A display part displays a time information and a setting information. The display part and the plurality of setting keys are included in the operation panel. A timer having a connector controller for switching that the input voltage is provided to several connectors is included in the plug receptacle. the main controller performs a time counting function by using the reference clock generated from the reference clock generator. The user sets an operation mode about at least one connector through the plurality of setting keys. The operation mode is displayed on the display part. The main controller controls the connector controller according to the set operation mode, so that the input voltage is applied to at least one connector.
