Sequenced switching over load circuit

Published:2011/7/16 3:19:00 Author:leo | Keyword: Sequenced switching, load | From:SeekIC

This circuit uses four diodes DN to form a circular counter. It can switch over the sequence of the loads under the control of input impulse signals. As the picture shows, except the indicator lamp, it can switch over any load with the current of 15 mA to 200 mA. When connecting the power resources, please click reset switch K to offer current to Lo. When K is cut off, the current passes through C2. After that, please open up D2, there will be current passing through I1.
