Nowadays, the market is flooded with a wide variety of switch sockets, but the quality and standards vary greatly, making it challenging for consumers to choose the right product. A switch socket is not just a functional home decoration item; it's also a critical component in ensuring electrical safety. The quality and materials used in these products play a vital role in preventing fires and reducing potential losses.
High-quality switch sockets typically have a smooth surface without burrs, and are made from imported high-grade PC materials that offer excellent flame resistance. However, some products may look smooth on the surface but appear oily or pale, with a rough texture. These can be dangerous, as they lack proper flame retardancy and may pose hidden fire risks for household appliances.

A genuine product’s panel is designed to be difficult to remove by hand and usually requires a specific tool. In contrast, many low-end or non-branded products can be easily removed by hand, which can lead to an unattractive appearance in both homes and public spaces. When selecting, press the face cover diagonally using your thumb and index finger. If one side feels loose while the other remains firm, it could indicate poor quality. A tight, secure fit suggests a more reliable product.
Testing the switch mechanism by tapping it can also reveal its quality. A smoother, more rhythmic sound indicates better performance, while a dull or uneven sound may signal poor craftsmanship. The smoother the movement, the better the internal components are likely to be.
There are two common types of switch mechanisms: slide-type and pendulum-type. Slide-type switches offer a strong, smooth feel, while pendulum-type switches are known for their crisp sound and slight metallic impact. Pendulum-type designs are often more stable, especially when it comes to arc suppression and longevity, making them a more mature choice compared to traditional slide-type models.
Double-hole pressure plate wiring is generally safer than screw-pressed wiring. It increases the contact area between the wire and the device, reducing oxidation and preventing loosening or poor contact. On the other hand, screw-pressed wiring can damage the wire if tightened too much, leading to a smaller contact area and increased risk of oxidation or aging over time. High-quality products typically use double-hole pressure plates for better reliability.
Switches with silver contacts offer superior conductivity, generate less heat, and provide higher safety. Copper contacts, on the other hand, perform significantly worse. Using tin-phosphorus copper sheets in sockets ensures better strength, flexibility, and elasticity. Brass reed sockets are durable and resistant to arcing, while gold-plated spring pins are highly resistant to oxidation, ensuring stable performance and clear signal transmission.
Most household switches are rated at 16A, while standard sockets are 10A. Air conditioners and water heaters typically require 16A sockets. Reliable products clearly label the current rating, while inferior ones may have unclear or exaggerated markings. Always check if the stated current rating is safe and accurate to avoid overheating or potential hazards.

Lamp accessories are various parts and accessories used to install, secure and connect lighting fixture. They play an important role, not only to ensure the normal operation of the lamp, but also to improve the use effect and aesthetics of the light.
There are many materials for making lamp accessories, generally speaking, there are metal, plastic, glass, ceramics, etc. Metal generally has a long service life, corrosion resistance, and should not be aged, such as iron product lamps, which have a long service life; Plastic lighting product have a short use time, a faster aging speed, and are easy to deform when heated; The service life of glass and ceramic lighting is long as well.
Nowadays, the lighting and lighting accessories industry uses metal materials as the most widely used base, generally used materials are zinc alloy, aluminum alloy, steel, stainless steel, etc. The use of technology is mainly electroplating, painting, oxidation and electrophoretic coating. With the current people to lighting accessories product performance requirements and environmental awareness improved, electrophoretic coating process has gradually become the preferred process for surface treatment of lighting accessories.
