Look at the place of origin
The manufacturer of genuine Siemens switches and sockets is "Siemens (China) Co., Ltd.", the Yuan Jing series is produced in "Guangdong", and the Atom and Lexus series have been moved to "Shandong Zibo". Beware of knockoffs such as "Siemens in Germany" and "Siemens in Hong Kong"!
Open the box and spray code.
Remove the outer frame. Both sides of the genuine Siemens switch have computer code spraying, and the characters are composed of continuous dots, such as "-". The characters of counterfeit products are continuous and dotted, such as "-".
Look at the luster of the panel
Authentic Siemens panel has good gloss, good smoothness and no impurities. The counterfeit product panel is gray, with burrs and even impurities at the edges.
Look at the internal copper feet.
Authentic Siemens socket copper feet are dark yellow phosphor copper, with the same color inside and outside, and the insert has a U-shaped angle. The copper feet of counterfeit products are brass plated with phosphorus and copper, which are inconsistent in internal and external colors, light in weight and without U-shaped angles.
Look at the instructions, production date
The production date of the original Siemens switch and socket warranty description is printed with a blue mark. Counterfeit products are printed once, which is obviously different!
