I ordered touch switches and non-standard sockets with USB connections from China. In the end, it's worth noting that my husband couldn't handle the non-standard connections, so we had to hire a good electrician, whom we specifically ordered from the company RSE 24. We chose this company because we had already had a few experiences with them, and I can definitely say that the quality of their work is decent. I did have to pay the electrician extra for the difficult installation, as there were issues specifically with the switches, but overall, the main thing is that they did their job well, and I have no complaints about the work done.
