The invention relates to a high-efficiency energy-saving environment-friendly controller which is composed of a voltage stabilizer, a contactor, an inductor, a zero line, a secondary live line, a main live line, a power supply lamp, a working lamp, a time controller, and the like, wherein the voltage stabilizer, the contactor, the inductor, the zero line, the secondary live line, the main live line, the power supply lamp, the working lamp and the time controller are arranged on a main device and an auxiliary device. One end of a switch is connected with the main live line, and the other end is connected with a fuse. One end of the voltage stabilizer is connected with the fuse, and the other end is connected with the contactor. One end of the contactor is connected with the voltage stabilizer, and the other end is connected with the time controller. One end of the inductor is connected with the time controller, and the output end is connected with the secondary live line and the zero line. The inner end of the zero line is connected with the inductor. The inner end of the secondary live line is connected with the inductor, and the outer end is connected with a controlled electrical appliance. The inner end of the main live line is connected with a switch, and the outer end is connected with an external live line. The working lamp and the power supply lamp are arranged at two sides of an assembled box. One end of the time controller is connected with the contactor, and the other end is connected with the inductor. The high-efficiency energy-saving environment-friendly controller has advantages of excellent performance, multiple functions, accurate sensing and controlling, high convenience in mounting and use, high efficiency, energy-saving performance, high reliability, high durability, low manufacture cost and high comprehensive benefit in use.
