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

        The Mercury is in a glass tube with two wires and the tube is attached to the bimetallic strip in such a way that the motion of the Mercury due to gravity as the strip moves will close the circuit between the two wires. The Mercury is just being used a liquid conductor.
