ABSTRACT:
A power-saving relay circuit for reducing power consumption from a power supply comprises a relay including a selectively energizable relay coil, a plurality of movable contactors, and a plurality of fixed contacts including first and second fixed contacts associated with each of the movable contactors. Each of the movable contactors is normally in electrical contact with the first fixed contact and responsive to energization of the relay coil for breaking the electrical contact with the first fixed contact and for making electrical contact with the second fixed contact. A current limiting circuit is coupled in electrical series circuit intermediate a selected one of the second fixed contacts and the relay coil. The movable contactor associated with the selected one of the second fixed contacts is capable of being coupled in circuit with the power supply for completing an electrical circuit through the current limiting circuit for energizing the relay coil.
A method is also provided for reducing power consumption from a power supply by a relay of the type described above. This method comprises providing a current limiting circuit in series circuit intermediate one end of the relay coil and a selected one of the second fixed contacts; and coupling the movable contactor associated with the selected second fixed contact with the power supply.
