Abstract
To improve energy efficiencies, supply circuits () for supplying switch circuits () have first supply modes for receiving first amounts of input power from sources () and providing first amounts of output power to output circuits () comprising control parts () of the switch circuits () and have second supply modes for receiving second amounts of input power and providing second amounts of output power. The first amounts of output power are larger than the second amounts of output power. The second amounts of input power are larger than zero and smaller than amounts of switch power necessary for operating the switch circuits (). The switch circuits () may comprise relays for switching loads (). The first amounts of input power may arrive via main contacts of the relays. Switches () may switch output signal levels. The relays may be bistable relays.
