Patent ID: 8716968

Claim:
An appliance control circuit for an appliance having a motor switchably connectable to a power line voltage, the appliance control circuit comprising: an electromechanical relay having a coil acting on a magnetic armature to open and close contacts across a first terminal and second terminal of an electrically controllable switch, the first terminal of the electrically controllable switch receiving the power line voltage and a second terminal of the electrically controllable switch providing the power line voltage to the motor; low-voltage logic circuitry receiving a low-voltage power and a low voltage motor control signal from a low voltage switch for controlling the electromechanical relay according to the motor control signal: a first power conditioning circuit receiving the power line voltage and providing the low-voltage power to the low-voltage logic circuitry at a power level insufficient for continuous operation of the electromechanical relay; and a second power conditioning circuit receiving power line voltage from the second terminal of the electrically controllable switch and providing the low-voltage power to the low-voltage logic circuitry at a power level sufficient for continuous operation of the electromechanical relay.
