Connecting Two Lamps to a Single Switch: Wiring and Configuration Guide

Hello,

Please help me connect the lamp to the single switch. The situation is as follows, I have a normal switch to turn on the light in the vestibule and I want to make a light in front of the entrance, so I drilled through the wall and let the cable out from the box under the switch. When I connect the wires to the switch, either the light is on in my house or outside. I've tried all the cable combinations and nothing. I would like the lamp outside to turn on when the light in the vestibule is turned on. Ultimately, I want a double switch, but if I don't have it, I would like to solve it in the above way.

In general, in this case, you have to connect the new lamp to the old one.

Can't you connect it to a switch?

If it is as I think, then ... the power supply from the RG goes to the lighting of the light catcher. N goes to the PE bulb on the housing as protection, and L goes from the can to the switch and back to the bulb.
The best solution, as my colleague Pawcio89 wrote, will be to connect the hoses. lighting under ext. least of all combinations, you will do the so-called chain.



Over time, when you put on a double switch, you can give a 4x1.5mm2 cable and you will have everything nicely separately.

Only that I can't connect to the lamp inside, the cable to the external lamp is already released under the polystyrene and enters the box where the switch is. It is a 3x1.5 cable. So the only solution is a double switch?

You want to say that 3 wires enter the box in which the switch is located and their other end is outside? If it is as I understood it, I don't know, but for me there will be no place to connect PE and N, unless I misunderstood something, correct me if I'm wrong.

damn well understood i.e. i'm in the shit

I don't think I have any further advice on how to do it, e.g. 4x1.5, because I don't want to expose myself to criticism of mods for advising something that may pose a threat to your health and life.
I also think that the electoral you don't have it, so maybe it's worth calling a specialist and telling him what you want and then he'll suggest you the optimal solution, but I'm afraid that with such a (wrong) 3x1.5, you won't be able to do without cutting out the polystyrene and possible hammering of the plaster in order to get to the lighthouse. int. if you have already laid plasters or going a step further ... forging in plasters to the box and to the switch to install it there, turn on. 2x.

If the installation is done correctly, i.e. the voltage reaches the switch box all the time and then spreads to the lamps, we have two solutions:
1- when from the box one 3x1.5 wire powers one lamp and the other 3x1.5 wire powers the other lamp. Then all the N-blue wires in the box should be connected together except for the switch, and the brown (or black) L-phase wire should be connected to one side of the switch, while the other going to the lamp No. 1 L-brown (or black) should be connected to the other side of the switch , the L-brown wire going to the lamp no. 2 should be connected to the same place if it is a single switch, and if it is a double switch, to the second output of this switch. PE-yellow-green wires are not used.
2- when a 3x1.5 cable from the box powers the lamp No. 1 and from this lamp with a cable (at least 2 cores) the lamp No. 2 is further powered, we have the following solution: L-phase cable and L-connector to the lamps, PE conductors are not used. In lamp No. 1 L- brown we fasten together, and N also together. When we have a double switch, we connect N in the box, L-phase as above, and L-powering lamp No. 1 on the other side and PE going to lamp No. 1 to the other flap (we use it as a phase one to power lamp No. 2). In lamp No. 1, we supply power normally, and we connect the yellow-green next to this lamp with the brown wire going to lamp No. 2, in lamp No. 1 the N wires are connected together.
It's a bit much, but that's because it's written in descriptive language.
Draw, check, connect and it must work.[/i]

Exactly yesterday I came up with a similar idea, it turned out that there are 3 cables going to the switch from the box and one is not connected. I connected it to the 0 in the can and then to the cable that goes to the bulb outside directly. In the switch, on the one hand, I gave the phase from the other, I gave 0 from the internal lamp and the second cable from the bulb from the outside. And it works :)

Thanks a lot for your help.
