<p>A multi-positional mercury switch (1, 2, 3) for use with miniature relays (4). The mercury switch apparatus has mercury wettable magnetic contact structures (11, 12, 211, 212, 222, 311, 312) supported in a sealed envelope member (10, 20, 30) supporting to magnetic contact structures with ends thereof extending from the envelope member for interconnection with terminals of the relay. A mercury holding assembly (13, 14, 23, 24, 33, 34) is slidably located within the sealed envelope member adjacent the magnetic contact structures and is responsive to an external magnetic field generated by electrical signals in a coil (40) surrounding the sealed envelope member for engaging the magnetic contact structures and establishing an electrical conducting path between the magnetic contact structures.</p> |
