The utility model discloses an energy-saving socket with low power consumption, which belongs to the field of energy-saving control, can sense the load change of a main control electrical appliance, and can achieve the full power-off of both the controlled electrical appliance of the main control electrical appliance and the power supply of the socket only by controlling the main control electrical appliance. The energy-saving socket with low power consumption is characterized by comprising an initiate button, a close button, an alternating-current relay, a delay power circuit, a sample detector, a control executive circuit, an indicating lamp, a main control output end, a plurality of controlled output ends and the like; a delay power supply is subjected to resistance-voltage reduction, rectification, filtration and voltage stabilization to be taken as a delay circuit power supply, and then is connected at the output end of the main control electrical appliance, so as to control whether the circuit is continuously powered on or not, according to the size of a signal formed by sample resistance, thus realizing control with one machine, achieving the full power-off of delay of series of device power supplies, and saving energy with zero power consumption. The energy-saving socket with low power consumption has simple circuit, low power consumption, economy and practicability, energy conservation, environment protection, and memory function.
