I want to build a bathroom mirror frame with integrated LED spot lights. Current comes out of the wall, there are already two on/off switches which control that single outlet. That is why I „believe“ I cannot simply replace (one of) the switches with a turn knob dimmer.
The frame is only 2cm thick where I want to place the knob for dimming. The knob itself does not need to provide on/off functionality, only control the dimming.
The lamps have more room and there would be room for a separate trafo. I have not purchased any electronics, yet, so I would be flexible.
To my surprise I have difficulty searching the net for setups like this, including this site. It sounds simple, but all parts I find are much too thick or it is unclear whether I could use them.
Can someone recommend a part that I can use for the knob and the electronics that follow that decision? (dimmer with input for that knob, plus LEDs) Most LED Spots I find have the driver already included and then just claim to be dimmable. They are either for 12V or 220V, but I don‘t care.
