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.he mercury relay thus allows for switching of higher currents with a small control current for a large number of cycles. They are often installed into automatic controllers that required extended periods of unattended continuous switching operation.
