Normally closed mercury relay, with coil around top of tube and adjustable angle.
A mercury relay (mercury displacement relay, mercury contactor) is a relay that uses mercury as the switching element.
They are used as high-current switches or contactors, where contact erosion from constant cycling would be a problem for conventional relay contacts.
Owing to environmental considerations about the toxicity of mercury, mercury relays are mostly obsolete, though modern encapsulated units still have applications. They are generally being replaced by solid state relays.
