what brand is the switch

1. SIEMENS comes first. SIEMENS of Siemens, we are all familiar with it. Founded in 1847, this German brand has always adhered to the German characteristics, strict and rigorous, and has carried out strict inspection on each product, making it a benchmark for the quality of Wumart. Siemens' power socket, because of its high cost performance, is well received by the majority of users, and its sales volume is the first, which is well deserved.

2. TCL Legrand ranked second in the ranking this time with excellent sales results. Legrand is a French brand founded in 186 and an international brand with a history of one hundred years. Its products are of excellent quality and excellent service, and are favored by the majority of users.

3. Simon and Legrand both fought for the runner-up, but Simon lost the game in the competition, and the ranking dropped from the second to the third. However, he has not lost his advantage, and he believes that with his own efforts, he will certainly catch up with Legrand. Another feature of Simon Company is that it is good at combining "new" things, new technologies and new materials.

4. Congratulations to the 4th place of Schneider Company, whose strength is not inferior to the other three. As the largest professional switch manufacturer in the world, Schneider Company is known as the "leader" in Europe. However, the market share in China is far behind the top three, and the sales volume of domestic brands is constantly improving, which puts them under great pressure. Schneider Company mainly relies on low-voltage series of professional products to gain a firm foothold in China market, and this type of products can be preferred.
