Illustration: How to identify the true and false Siemens switch?

Siemens screws are relatively long, and the thickness of the screws is the same. The fake Siemens matching screws are shorter and the screw tips are thinner.

Panel gloss: The real Siemens panel has good gloss, the fake surface is not smooth and dull, and the workmanship is rough.

The left side is genuine, and the right side is imitation. The difference is simple. As can be seen from the appearance, the genuine cable TV hole is black, and the imitation is white. The genuine outer ring metal ring with shielding is made of good material and has concave-convex grid, which can make the closed-circuit plug and socket contact more closely and is very humanized. Imitation goods are a thin circle of iron-like materials, and even the gaps at the junction of the circle are scary.

Brand store: Siemens switch

The circuit board on the back of Siemens cable TV socket was changed this time. On the left is imitation, and on the right is genuine. It is also clear at a glance. The left side of the circuit board and solder joints are rough, and the right side is neat and smooth.

Imitation tablets and fixing clips are common alloys, and genuine products are all copper, neat and bright. In addition, the production date on the panel is often around 2005, and the genuine product should be at least after the end of 2006.

Take a close-up of the genuine product. The blank space next to the module has a clear trademark and number. Next is the comparison of telephone sockets. There is little difference from the front, mainly depending on the smoothness of each opening. Imitation goods often have many small burrs. In addition, the color of the imitation goods is slightly yellow compared with the genuine goods, so the protective piece of the telephone jack that can be lifted and lowered is not very smooth, and it will even retract if it is pushed too hard. Did everyone see which one it was?

Back, true or false. The production date of this batch of imitations is 2005XXXX, and the color of the imitations is obviously yellow.

On the back of the genuine product, there are clear digital marks similar to closed-circuit sockets in the blanks on both sides of the module, and there are clear made in China above the module, and the trademark logo of Siemens below.

There is no number on the back of the imitation, and there is no origin mark. The most terrible thing is that you can see the huge round burr formed by the mold gate on the installation hole at the upper right.

Another copy, the production date is marked as 200508 1 1, which is exactly the same as this one, and even the big burr on the card plug has not been removed.

Siemens official website Enquiry

Since June 2009, all Siemens switches have been equipped with double security. The first anti-counterfeiting is the anti-counterfeiting label attached to the packaging bag, and the second is the 20-digit anti-counterfeiting code on the product bracket. If you send it by SMS, you won't find anything unusual.

At this time, you can go to Siemens, China and official website to inquire.

By the way, I'll tell you a little trick (provided that the appearance and quality of the product are not much different from the genuine product, and the product packaging, anti-counterfeiting code and instructions are highly simulated):

The telephones, network cables, TV sockets and switches sold by JS are relatively expensive, so the profits from counterfeiting are higher. Generally, the number of these sockets is small, and they all need to be inquired; Generally, if there is no problem with these questions, they should not be false. At the same time, for the sake of safety, it is best to check the 5-hole socket. If there is no problem, it should be almost genuine.
