According to statistics, in 2011 China's export volume of relay has been reduced, but the export value has increased, indicating that the export value of relay increased, relay is of more technological content, that is, the share of high value-added relay exported significantly increased, it is contributed to the overall development of the relay. aIn relay industry, value-added products has been greatly improved, in some areas it has gradually replaced imported products.As implementation and the gradual deepening of China's top ten industrial promotion policy, the usage and applications of relay will be continued to expand. The traditional electromechanical relays will remain no less than 7% -8% growth rate, the development of solid-state relay is close to 15%, while the special relay will be of the rapid development which is more than 20%.China relay industry will gradually accelerate the pace of change from "manufacturing" to "create power", the situation rom export-led to domestic demand, exports keep pace will become increasingly prominent, particularly to enhance the capture of high-end products, the trend will be more demand-driven clear. Light relay, temperature relay, the relay of high-frequency relays and other special applications continue to expand,domestic manufacturing technology, quality and production levels can not meet market demand. Greatly improve the level of automated testing, the manufacture, assembly, automation engineering capacity to the world advanced level, or that rapidly reduce the level gaps with the developed countries in manufacturing process .To develop new products to pry open new markets.
