Anonymous users2024-01-24Do you have a junior high school physics book at home or with friends? I remember learning about electrical circuits when I was learning (like a lamp in a hallway, can you turn it off when you turn it on downstairs). The diagram is as follows..../ ……
Explanation: Since I don't know how to draw on this, I simply drew it with symbols.
Note: + stands for the live and neutral lines.
… |It means that the wires should be connected together.
It represents two switches.
0 is for electric light.
It may not be perfect, this is just a circuit diagram, you can adjust it according to factors such as the structure of the house, and the light will be on (whatever you use, the light will be on) OK

Anonymous users2024-01-23Is there a plug in the bedside lamp with two wires? When one of the wires is disconnected, there will be two wires, and you can connect the two wires to the two binding posts of the switch. If you don't understand something, mention it again.

Usually we only connect the electrical switch to the live wire, and nothing is connected to the middle of the neutral wire.

Anonymous users2024-01-21Upstairs, it's about the switch in the middle. That's how I picked it up. But it's broken!
It's better to buy a key switch, because after all, you need to turn on the light when you wake up from sleep at night, it is very convenient, and when you twist it with a dimmer light, you may knock the light down.
The installation height of the hotel bedside lamp is about one meter. Installation tip: The bedside lamp should be higher than the sitting and lying position. >>>More
It is connected in the same way as the switch, and two wires are OK.
The bedside lamp has two terminals with a pull switch, the input is connected to the power live wire, and the output is connected to the lamphead wire. >>>More
The rotary switch of the bedside lamp is two in and two out, the input terminal is connected to a live wire and a neutral line to provide 220V power supply for the switch, and the output terminal is also a fire and a zero to provide working voltage for the load bedside lamp, and its voltage is determined by the size of the trigger signal given by the knob switch, and the opening of the thyristor is controlled to control the output voltage of the thyristor to control the brightness of the bedside lamp.
