Comment on Do I need a relay or something else entirely?

AC and DC are different, and 230V is nearly TWENTY TIMES the rated voltage for the switch (and possibly the lamp you’re using).
I’m all for DIY and experimentation, but this is headed rapidly towards a large incendiary event which insurance may decide they are not going to pay for. Mains voltage is not to be fucked with. There are rules and regulations around how things are built to be allowed on to the market for a reason. I suggest you get a 12V transformer (certified, not from aliexpress) and work from there.

Yes. I am aware that this was not the smartest move. In my defense, I did this conversation years back, when I was younger and with the help and expertise of my dad and his dad. Who both should have known better as they’re experienced in electrical work. The switch looks solid enough (see my other comment for pictures), which is probably why they never realized the mistake, and to be fair, it has worked without problems for years of daily use. (Which is not to say I trust it looking back. The switch does not offer a ton of isolation of the mains power…)
