How to Distinguish the Quality of the Rocker Switch?





1. 厚铜片提高了电流流通能力,降低了铜件的电阻。

2. Strong resistance, especially for some sockets, not easy to deform. Even if the socket is used for a long time, it can maintain the appropriate clamping force. The Guancheng plum socket ensures that the socket and the plug are tightly connected to reduce the arc.

3. No rust, reduce the problem of increased resistance and heating caused by rust.

4. Less riveting, one piece of copper in the whole, further reducing the riveting and rivet heating.


Many years ago, the use of brass as current-carrying parts in sockets was the mainstream; nowadays, brass parts are still used as current-carrying parts, and the quality is definitely inferior. The appearance of brass is bright yellow, the texture is soft, abrasion resistance but not ambition in terms of durability (elasticity).

After the brass is used for a long time, the appearance of the copper parts will be oxidized and rusted, the color will become dark, and the touch resistance will be increased; after repeated plugging and unplugging, due to poor resistance and severe deformation of the brass sheet, it is often unable to pick up electricity or due to poor touch It forms an electric arc and cannot guarantee the safe use of electricity.

Now mainstream sockets use tin-phosphorus bronze as copper material. The tin-phosphorus bronze alloy has a purple-red appearance, and its features are its very high strength, strong elasticity and excellent corrosion resistance. Even after long-term use, its appearance will not be oxidized and corroded, the insert sleeve will not be deformed, and the appropriate clamping force will always be maintained.
