Various switch driving circuits are controlled by a variety of micro-control chips. Since many factors such as power interference and port status may cause malfunction,a design scheme to prevent malfunction is introduced in this paper. The cir-cuits of power testing,electronic switch and electronic protection are adopted in this scheme to achieve precise control. The scheme is simple and practical,and has low cost. The circuit has been applied in the smart meters,and has a reference value.
