There is only one bulb on the balcony that controls the switch in the living room, how to design it

It is generally not advisable to take an outlet above the lighting circuit, unless you are going to use an electrical appliance with less power. The simpler way is to connect the control switch of the living room directly, connect three wires from the lamp head, two of which are used as socket wires, directly connected to the zero and live line of lighting, and the other is used to control the lamp, you can choose the socket with a switch, so it is more convenient to use.

You can choose to connect an external line directly to the base, which is recommended by a professional electrician. Or connect a plug board, and then plug in the base to answer the phone, which is more flexible. Choose your own according to the situation. Please adopt if it helps.

I put the switch of the living room to control the balcony light short! Go from the lamphead to the power of the 220! Then lead out a wire press and switch to control the balcony light! That's it. Does the socket have to draw power from the lamp?
