A switching and control system for controlling video game boards of video game machines comprises a CPU, input/output circuits and a system RGB generator. The control functions are governed by the CPU which has a microprocessor and a circuitry for the program hardware. The switching function is performed through the input/output circuits and switches, as instructed by the CPU by connecting the power supplied by a power source to provide an audio signal for loudspeakers and a color signal (RGB) and a synchronism signal for each of the selected video game boards.
