the most innovative point of this switch design is to enable our users clearly identify each light is controlled by which different witches. Based on the traditional switch design standard, we figure out a small slot above the switch, which can place light label. The installation is simple and practical, we just need to insert the different printed label into the different slots. There is a small hole in the notch of the label plate, users can use smaller tools to eject the label paper.

My name is Liquan Li, now I am the assistant professor of Shenzhen Technology University, also as a member of Shenzhen Design Union, and the industrial design expert of Economic, Trade and information Commission of Shenzhen Municipality. Up to now, I have received 28 industrial design awards, 14 design patents, and 5 design papers (3 for CSSCI). As a teacher, I decided to use the design to help the children and the elderly in the poor areas, which were all free of charge. I named the plan as a "dolphin program".
