The three-phase socket has three lines, which are phase, neutral and ground.
1, look at the box (if any), there should be a floor in the box, that is, the terminal strip with PE mark (or ground mark). Facing the socket, the left side is zero line and the right side is a fire line. The installation of the light switch is a technical activity, but also needs attention. Here is how to install the light switch and the problems that need attention. Distinguish the power line (L), neutral line (N); 2, installation method: power line → switch into the terminal block → switch outlet terminal → lamp intermediate terminal → lamp outer ring terminal → power supply line. Note: The fire wire is connected to the middle terminal of the lamp head to prevent people from getting an electric shock when cleaning the lamp (or replacing the lamp) and cleaning it to protect life.The wireless remote control light can be implemented with a wireless remote control module. One is a radio remote transmitter (ie the remote control in your hand) and the other is a radio remote receiver (used to receive the transmitter signal and control the light bulb). When a button is pressed on the transmitter, the transmitter encodes, modulates, and then transmits the signal through the radio wave; the receiver receives the radio signal sent from the transmitter, and obtains control information through decoding to cause the corresponding pin to occur. The change causes the relay to operate (the relay is equivalent to an electric switch, which is used to control the rear 220v AC circuit), and the circuit in which the bulb is located constitutes a loop to emit light.
