Mercury is used in some electrical switches to "wet" the contact to prevent sparks from pitting the contact. Also, old style thermostat uses mercury to roll side to side on gravety to form a switch.
Mercury is still used in instruments as indicators because the surface tention makes it to bulge UP, not down like water making it much easier to read. Also, it has very low expansion/contraction due to temperature changes.
