<A HREF="mailto:firstname.lastname@example.org">email@example.com</A>I have two old brass lamps that are touch lamps for turning them on and off. I want to paint them to make them more current in appearance and wonder if the touch feature of them will still work after I paint them. Does anyone know the answer?Will the feature still work after painting?What kind of paint do I use to paint the lamps?

experience shows that any coating on the brass will make the touch control massively insensitive. paint them so the paint stays on, and it's not going to work. you have to touch metal.
without going into the electronics much, and I've built a set from scratch, the CMOS gate that signals power is already heavily isolated with a 2 to 10 meg resistor, for chip failure protection. the thing works by picking up stray hum on the touch surface from your finger. so insulating it is a no-go.
