Generally, most of the techniques for shutting down or reducing standby power are being developed for power outlets. However, in order to cut off the standby power in the outlet or the multi-tap, there was inconvenience to the user that the user had to directly reach the outlet. In order to solve this problem, a remote control method using a remote control has been introduced. However, this method requires additional power for always operating the remote control receiving module and the control module in the outlet, Other problems arise.
On the other hand, as shown in Patent Document 1, there is a system in which a mechanical operation switch is mechanically attached directly to the end of a power plug to enable a user to turn on / off the power supply at the plug end. It is inconvenient for the user to directly reach the end of the power plug inserted in the outlet and operate the switch of the power plug.
In addition, as shown in Patent Document 2 below, there is a method of monitoring the user's remote controller operation or whether an overcurrent of a load device is generated, so that power supply from the power plug stage to the load device is interrupted when an overload occurs. However, this method requires an additional overcurrent detection sensor of the load device and a microcomputer built-in digital control circuit and a non-contact switch for the judgment, so that the system is still very complicated, and at the same time, constant power for the control means is additionally required The standby power saving efficiency is greatly reduced. Moreover, since it is a sensing and control logic method that is dependent on whether the load device is overloaded, it may cause a catastrophic failure to the load device in case of malfunction of the sensor or the microcomputer.
