Reply to My thermostat uses the expansion/contraction of a drop mercury to conduct electricity and trigger when to turn off and on. by Iain_MS
The mercury doesn’t expand and contract. The mercury vial is mounted on a bi-metal coiled spring that causes the vial to tilt during a temperature change. When it does, the mercury blob rolls to the other end of the vial and opens (or closes) the circuit.
