It's a shame the wiring to this this lovely switch may have caused a small fire years ago. I've wondered what it was, but it was unidentifiable under seven layers of paint and failed to turn anything on or off. Turns out it was disconnected at some point. Inside the wall Paulie found charred boards and sections of lath and plaster blistered and blackened. The switch polished up nicely (that bottom red button is a nightlight, bulb filament still intact!), but it will have to go on the display shelf instead of back in the wall.
