Legrand's global expansion is basically achieved through acquisitions, and entering the Chinese market is no exception, in 2005, Legrand acquired the "Whampoa Military Academy" TCL of domestic electrical enterprises, which was a sensation, and now it is difficult to see TCL's socket on the market, but there will still be many links related to TCL when searching for "Legrand" on the search engine.
 
In China, Legrand has 7 factories, distributed in Beijing, Shanghai, Guangdong and other places, in the switch and socket industry, product quality and safety are closely linked, so in the field of electrical products, well-known manufacturers are using the production mode of self-built factories, although the cost is slightly higher, but the self-built factories can implement stricter quality control strategies, product quality is more reliable than OEM enterprises.

The appearance of Yidian is also more diverse, divided into magnolia white, fine grain gold, alcohol sand steel and ice white series, although there is still a certain gap between ice white and Yiyuan series workmanship, but the addition of transparent PC makes the three-dimensional sense enhanced.
