This paper discusses the design and implementation of a wireless remote switch control system composed of a main controller (MCU) located in the control command center and a digital control unit (DCU) distributed in the field of the controlled device. They are used microcontroller 89C5 1 as the central processor, control command data can be transmitted through the wireless frequency modulation, remote control relay on-off. The system is applicable to a wide range of scalability
