Container House Light Bulb Wiring Diagram

The wiring of light bulbs in container houses can refer to the common home lighting circuit wiring methods, as detailed below:

Single-control lighting circuit
Suitable for scenarios such as entrances and balconies where only one switch is needed to control the light bulb. When wiring, it is important to distinguish between the live wire (red or brown) and the neutral wire (blue): the live wire is connected to the L terminal of the switch, and a control wire is drawn from the L1 terminal of the switch to connect to one end of the lamp holder; the neutral wire is directly connected to the other end of the lamp holder. This method controls the circuit's on/off state through a single switch, enabling the light bulb to be turned on and off. Key point: The live wire must pass through the switch before being connected to the lamp holder to avoid the risk of electric shock caused by direct connection of the neutral wire.

Double-control lighting circuit
Suitable for scenarios such as bedroom doorways and bedsides where two switches are needed to control the same light. When wiring, the power live wire is connected to the L terminal of the first double-control switch, and the L1 terminals of the two switches are connected to each other, as are the L2 terminals, using connecting wires (a total of two connecting wires). The L terminal of the second double-control switch draws a control wire to connect to the lamp holder, and the neutral wire is directly connected to the lamp holder. Key point: The connecting wires must strictly correspond to L1 with L1 and L2 with L2 to avoid cross-connection that could result in control failure.

Triple-control lighting circuit
Suitable for scenarios such as staircases in duplex houses and long corridors in large apartments where three or more control points are needed. The wiring sequence is as follows: the live wire is connected to the L terminal of the first double-control switch at the beginning, and the L1 and L2 terminals of the first double-control switch are connected to the L11 and L21 terminals of the intermediate switch, respectively; the L12 and L22 terminals of the intermediate switch are then connected to the L1 and L2 terminals of the last double-control switch; the L terminal of the last double-control switch draws a control wire to connect to the lamp holder, and the neutral wire is directly connected to the lamp holder. Key point: The intermediate switch must be a "double-pole double-throw switch" (also known as an intermediate switch), and the connecting wires must be connected in sequence step by step to ensure normal multi-point control functionality.

One-light double-control plus five-hole socket circuit
Suitable for scenarios such as bedsides in bedrooms where both lighting and socket control are needed. The wiring of the five-hole socket follows the principle of "neutral on the left, live on the right, and ground in the middle": the L terminal is connected to the live wire, the N terminal is connected to the neutral wire, and the middle terminal is connected to the ground wire; the double-control switch part is the same as a common double-control circuit, with the power live wire connected to the L terminal of the first switch, connecting wires linking the L1 terminals of the two switches to each other and the L2 terminals to each other, and the L terminal of the second switch drawing a control wire to connect to the lamp holder, with the neutral wire directly connected to the lamp holder. Key point: The live wires of the socket and the switch must be independently connected to avoid overload risks caused by sharing.
