The present invention relates to a wireless standby power cutting off system that cuts off standby power for an unused device through wireless control in order to cut off standby power to be unnecessarily consumed when power supply voltage is supplied to a device to save electricity, which is produced by using incoming crude oil, as much as possible. An apparatus for selectively cutting off power to be supplied to a device includes a button used to input an on/off command of the device or a switch; a transmitting unit for transmitting an on/off signal of the switch by the input into the button; an auxiliary transmitting unit for transmitting an on/off signal of the device by the input into the button; a remote controller including a first power supply unit equipped with a battery to supply power; and a second power supply unit including a feeding unit constantly connected with power, an output unit for supplying the power connected from the power supply unit to the device, a cut-off switch for powering on or off between the feeding unit and the output unit, a receiving unit for receiving an on/off signal of the switch transmitted from the transmitting unit of the remote controller to turn on or turn off the cut off switch; and a second power supply unit equipped with a rechargeable battery to supply driving power. |
