    So, on the occasion of the renovation, I decided to change the switches. These are touch switches that are installed to the box by screwing two screws on the side.
    Unfortunately, my boxes in the walls are of the old type, they do not have holes for screws, and all the switches were mounted on plates stretched to the sides.
    Question: how to install it in a civilized way without replacing the boxes? The renovation is finished, the walls are painted, the finishing coats are ready, etc. The block is made of a large slab ...

    If you gently remove the box and insert the appropriate one on the plaster in its place, it will not be visible from under the switch frame.

    Have you checked if the new touch switches will work. Because replacing cans may be the least of your problems.

    I bet they won't work because they still need N. And here there will probably be a shortage in the can.

    Two-wire installation with "zero" - no neutral.
    I will see if it is possible to replace the can, but it seems to me to be a breakneck solution in a large slab ...

    You'll do it calmly. Not by force, gently. In half an hour, max an hour with one piece you can do it. Worse than what the colleagues above wrote ...

    Some touches work normally in series on phase, don't need N.

    No need to forge whole cans. All you need is a sharp knife and a decent glue - cut out the appropriate fragments in the rim of the old and new cans and paste the new ones with holes into the cutouts of the old one, even on thermo-glue. The switch, especially the touch switch, unlike the socket, is not loaded with a pull-out force.

    Ok, I'll try the replacement option. The only thing that worries me a little is this big plate, after all, it's all very hard and difficult to work with.
    And what is the problem with missing N?

    Please provide the type or picture of the back of your circuit breaker. After all, you have an old tin, why do you want to process reinforced concrete?

    How many wires are under this switch in the old box and what kind?

    But you don't have to forge concrete, you just have to "pick out" the can from the inside, first the plastic, then slightly forge the old gypsum to make some slack for mounting the new can.

    Such that there are touch switches/dimmers that work without N, but also those that need it. If you have the latter, and there is no N wire in the box - all your effort to replace the box is in vain, because you have to buy another one anyway. And then you can find those that have a traditional, strut mounting method and the box does not need to be replaced.

    It would be easier to advise if you posted photos of the box and the back of the switch.

    These are the switches "B-LINE single 1GW touch switch".

    Why "unfortunately". You have L and L1, so you don't need N according to the link you provided.

Topic summary

The discussion revolves around the installation of touch switches in old-type electrical boxes that lack screw holes. The user seeks a solution to install the switches without replacing the boxes, as renovation work has already been completed. Various suggestions are provided, including gently removing the old box and replacing it with a compatible one, using glue to attach new boxes with screw holes, and ensuring the touch switches are compatible with the existing wiring, particularly regarding the need for a neutral wire (N). The B-LINE single 1GW touch switch is identified as the model in question, which does not require a neutral wire for operation.
