I have not seen that, not in houses. I saw it in a water tank we had 
with a buoy operated switch. Something would change balance and the 
mercury in two glass bubbles would make the contact. The thing was 
placed outside of the Uralita reservoir. Then would come a strong wind, 
move the switch housing, and the reservoir would run empty, the mercury 
did not make contact.

Eventually we replaced it with something like this:

Much more reliable.

There are gallium thermometers.
