It's under the enclosure on a 1910 convector in the dining room. The wires disappear through the floor into the sheetrocked ceiling below and there's nothing in the boiler room to indicate its presence.
Some kind of temperature limiting device when the switch is in the "on" position? When it reaches setpoint, it closes a valve?
Often wrong, never in doubt.

in the convector in the dining room? 1910 house? Gilded age?
It looks like a bell/buzzer to call the help to bring the food or to clear the dishes. I see all kinds of these call devices in old cribs that I work in. Some have little flags that pop out of a wall.
If I was there, I could probably find out what it is. I'm that way.
I see alarm installers who run wires where no wire dared to go. But they went anyway. It's an art form.
