If there is water on it, there is a risk of electric shock.

In addition, in the case of an outlet fixedly installed on a wall or a fixed place, when a user pulls out a plug, a user often pulls out a plug by pulling an electric cord instead of a plug. In this case, the wires of the plug terminal and the electric cord are disconnected. It does not have the problem that electric, electronic product becomes unusable.

Therefore, in FIG. 5 (a) and (b), the plug 10 is pre- filed in view of the above-described conventional problems. The plug 11 includes a switch 11 for turning on and off power to the plug 10, and As the switch 11 is turned on and off, a lamp 12 is turned on and off, and the switch 11 installed in the plug 10 is "+" as shown in FIG. 5 (b). Only one of the two wires can be turned on and off, resulting in the power continuously flowing through the remaining one wire in which the switch 11 is not installed. "The two wires are no different from the plugs installed directly connected to both side plug terminals, respectively, and the switch 11 and the lamp 12 are installed, and only the structure is complicated, and manufacturing costs are increased.
