Permanent magnet switches are the future development trend of the switch industry, and the industry is in a period of growth. Based on the design concept of streamlining components, permanent magnet mechanisms have performance indicators that are clearly superior to traditional spring switches in terms of longevity and reliability. Currently, the domestic market capacity of permanent magnet switches is about 1 billion, accounting for about 5% of high-voltage electrical switches. Currently, the market penetration rate is still low, and the industry is in the market introduction stage. The speed of promotion of permanent magnet switches is the result of a multi-party commercial interest game among market participants. Currently, there are few manufacturers of permanent magnet switches, and the competitive pattern is relatively moderate. Tread and Yongda Group are leaders in the international/domestic market, and both are manufacturers specializing in the production of permanent magnet switches; however, the most famous switch manufacturers at home and abroad, such as ABB, consider the impact of new technology on the original spring switch business and overall commercial benefits, and still only follow up on technology. However, among downstream customers, large industrial customers such as steel and metallurgy, which operate switches frequently, are more open to this product, while they are still cautious about power grids that are sensitive to product prices and require a low number of operations. The company is a leading domestic permanent magnet switch technology and scale enterprise. The company has always attached importance to R&D investment, so that the company is superior to its peers in key technical indicators such as maximum mechanical life and maximum rated current range of the operating mechanism, and has a rich product range and complete specifications. The company has been working in the steel, chemical, coal and other industries for many years, cultivating a number of loyal industry customers, and its sales area has spread all over the country without local market dependency. In 2009, the market share was about 22%. The company's diluted EPS for 2011-2013 is predicted to be 0.64 yuan, 0.83 yuan, and 1.02 yuan, respectively. Based on the valuation level of contract companies, it is recommended that the value be 25-30 times that of 2011, or 15.97-19.16 yuan, in the secondary market. Risk warning: The speed at which the permanent magnet switch market unfolds is uncertain; gross margin may decline.
