The disclosure relates to high gain electrical relays which are operable at very low power levels and which, when arranged in a relay system with impedance matching to an energizing power source, are operable at the low power levels used in energizing integrated circuits. The relays utilize nickel-titanium...http://www.google.com/patents/US3968380?utm_source=gb-gplus-sharePatent US3968380 - High gain relays and systems
