Hello. I have a problem with connecting the Legrand stair switch, consisting in the reverse connection of these switches. The case is as follows: according to the scheme here the power goes from the first to the second switch. The lamp is connected to the second one, but in my case the power...

It doesn't make any difference.

Flip the image 180 degrees and you will have a solution. It makes no difference whether the power comes from the left or right.

From your description, I conclude that you are doing the so-called mirroring the connection and it should work for you.

Apparently I was misunderstood. The point is, there is one switch at the top and a lamp. And the power supply is connected up there. From the top switch, a 3x1.5 mm2 wire is run to the other one at the bottom. I repeat the question. I would best ask you to sketch how to connect it.

A colleague wrote wrong Unfortunately, with a 3x 1.5 cable you will not do it, more wires are needed. Unless it's a different wire. Three phase cores are needed, plus N, PE

Hello! If you have a 3x1.5 wire between the switches, then on 1 you give power L the next 2 correspondence wires between the switches, and connect the 3rd wire to terminal 2 of the switch and connect it to the lamp in 1 switch (you already know the neutral and PE). ,, .Regards.

At the top, L and N and PE come out in the switch box. L to the switch, while N and PE directly to the floor lamp. From this box at the top, 3 wires go down to the other. 3 wires between the switches are not enough? According to only the phase veins go between them. Is the diagram from entry # 7 correct?

Man, how many can you draw one and the same diagram. It doesn't matter if the switch is downstairs or upstairs, the current does not distinguish it. Call an electrician if the topic is beyond you. I close. 3.1.17. Do not post very basic questions, the answers to which can be found in the instruction manual or publicly available sources. Do not take the attitude that I am due. Take care of the level of questions and discussions. Thank you.

Hello.
I have a problem with connecting the Legrand stair switch, consisting in the reverse connection of these switches.
The case is as follows: according to the scheme
here the power goes from the first to the second switch. The lamp is connected to the second one, but in my case the power goes from the second to the first switch, the lamp is connected to the first one. There is a three-wire cable between the switches. How to connect it so that it works properly. I was looking on the net, but I did not find the connection diagram for my case. Please help. Thank you in advance.

At the top, L and N and PE come out in the switch box. L to the switch, while N and PE directly to the floor lamp. From this box at the top, 3 wires go down to the other. 3 wires between the switches are not enough? According to only the phase veins go between them. Is the diagram from entry # 7 correct?

Topic summary

The discussion revolves around the connection of a Legrand stair switch where the user faces issues due to reverse wiring. The user describes a scenario where power is supplied to the second switch instead of the first, with a three-wire cable running between them. Various responses suggest that the wiring can be mirrored without affecting functionality, and that the orientation of the switches does not matter. Some participants provide diagrams and clarify that a three-wire cable may not suffice for proper connections, indicating the need for additional wires for neutral and protective earth (PE). The conversation emphasizes the importance of understanding the wiring scheme and suggests consulting an electrician if the user is unsure.
