Two-key light switch wiring diagram
As you can see, the phase and zero conductors from the distribution panel enter the junction box. Next, the input “zero” is connected to the zeros of the two bulbs, and the phase is conducted to the two-key switch, from which 2 new phases for each of the lamps emanate. This wiring diagram is presented without grounding. In the presence of "ground" (which is mandatory), the PE wire must be connected in the same way as neutral. The following shows how to connect a double light switch in a grounded network:
We draw your attention to the fact that the most effective wire connection method between themselves - the terminals of the car. All that is needed is to insert the bare wires into the terminal strip and fix them with a special flag.
We also recommend that you watch the video instruction for connecting the wires in the junction box with your own hands:
If you are interested in the option of mounting without a junction box, we recommend that you read the articlehttps://our.electricianexp.com/en/sxema-elektroprovodki-bez-raspredelitelnyx-korobok.html
That's the whole scheme of connecting a two-key light switch to two bulbs. As you can see, wiring is quite simple, the main thing is not to mix the wires.
