Title. We keep ours at 75F, parents do 77F, and in laws 68F. It made me curious what everyone else keeps theirs at?

older ones are often electrical, but not really electronic. they use a bimetal strip that bends due to changing temperatures, to complete a circuit at the point you set the slider. it’s actually a really fascinatingly simple bit of tech.

Mine growing up used a bit of mercury in a sealed vial mounted to that bimetallic strip.

any idea what the mercury was for? something about getting the heat in and out of the strip faster maybe?

Yeah, sorry. It was the switch! Two wires on one side. When the capsule tilts from the strip/coil it makes the electrical connection.
