BSTAR teaches everyone if you judge the quality of the ship type switch, rocker switch

The ship type switch is also called the rocker switch. So how do you think about the quality of the rocker switch? The quality of the ship type switch is mainly determined by the internal copper parts. The copper parts are the key components to ensure smooth current and reduce heat generation. The high quality ship type switches are made of high quality copper parts, which are resistant to oxidation, toughness, thick copper sheets and less riveted. They are the four indicators of the quality of the socket copper parts.

1. The copper piece is thick, which improves the current passing ability and reduces the resistance of the copper piece itself;

2. Strong toughness, especially applied to the socket socket part, not easy to be deformed. Even if the ship type switch is used during long-term use, it can maintain a proper clamping force, ensure the tight connection of the terminals, and reduce the arc;

3. Anti-oxidation, no rust, reduce the increase of resistance and heat caused by rust;

4. Less riveting, preferably a whole piece of copper, further reducing the breakage of the riveted part and the heating of the rivet.

In the past N years ago, the use of brass as a current-carrying member for the ship type switch was the mainstream; now, the current-carrying member is still used as a current-carrying piece, and the quality is affirmative. The appearance of brass is bright yellow, excellent electrical conductivity, soft texture, wear resistance but not good performance in terms of oxidation resistance and toughness (elasticity). After long-term use of brass, the surface of the copper part will be oxidized and rusted, and the color will become darker, which will increase the contact resistance. After repeated insertion and removal, the brass piece will have poor toughness and severe deformation, often failing to take power, or due to poor contact. An electric arc is formed and power cannot be used safely. At present, the mainstream ship type switches use tin phosphor bronze as the copper material. The appearance of tin-phosphorus bronze alloy is purple-red. The biggest feature is its high fatigue resistance, strong elasticity, excellent corrosion resistance and oxidation resistance. Even after long-term use, its surface will not be oxidized and corroded.

Consider the thickness of the copper piece. If you can‘t open the product for visual inspection, you can use the simple hand weight. The more the copper parts are used, the heavier the weight of the socket. The big brand of socket products is basically made of tin-phosphorus bronze as a current-carrying part, so as to ensure the normal service life of the socket for more than 12 years. Like the Hongju brand‘s ship type switch, the electronic switch power socket adopts the integrated socket copper piece. It adopts the continuous mold process and selects the high-quality tin-phosphorus copper high-precision belt for one-time processing to avoid excessive riveting points and reduce the material itself. The resistance of the rivet joint is reduced, and the rivet heat is reduced. The safety of the socket is greatly improved. It is understood that the tin phosphor bronze material selected by the macro socket not only has good electrical conductivity of copper, but also has good elasticity, and is excellent in fatigue resistance, corrosion resistance and oxidation resistance. In order to make the performance of the socket more perfect, the thickness of the copper parts of Sanxiong·Aurora socket is all above 0.6mm, which ensures that the clamping force of each series socket is stronger and the plugging is more stable. After more than 15000 times, it can still be used normally, much higher than 5000 times. National standard.
