How to judge the quality of a rocker switch?

The copper components inside a rocker switch, or electronic switch socket, are crucial for ensuring smooth current flow and reducing heat generation. High-quality electronic switch power sockets use superior copper components that are oxidation-resistant, durable, and have a thick copper sheet with minimal riveting.

These are the four key indicators of a superior socket's copper components. So, how can one distinguish the quality of a rocker switch?

1. Thicker copper sheet increases current carrying capacity and reduces the resistance of the copper sheet itself.

2. Strong pressure resistance, especially suitable for sockets, and not easily deformed. Even after long-term use, the socket maintains appropriate clamping force, ensuring a tight connection between the socket and plug and reducing arcing.

3. Oxidation resistance, no rust, reducing the problems of increased resistance and heat caused by rust.

4. Fewer riveting, ideally using a single copper sheet, further reducing rivet connections and heat generation.

Years ago, brass was the mainstream material for current-carrying components in sockets; today, brass parts still used for current-carrying components are of extremely low quality. Brass has a bright yellow appearance, excellent conductivity, and a soft texture.

While it offers good wear resistance, it lacks ambition in terms of oxidation resistance and elasticity. Over time, brass components will oxidize and rust, darkening in color and increasing contact resistance;

Due to poor resistance, it deforms severely, often failing to conduct electricity or causing arcing due to poor contact, compromising electrical safety.

Currently, most sockets use tin-phosphor bronze as their copper material. Tin-phosphor bronze alloy has a purplish-red appearance and its most prominent characteristics are extremely high fatigue strength, excellent elasticity, corrosion resistance, and oxidation resistance.

Even after long-term use, its surface will not oxidize or corrode, and the socket will not deform, maintaining appropriate clamping force. Considering the thickness of the copper components, if visual inspection of the product is not possible, this is a viable option.
