Selection skills of socket
Switch socket structure
At present, there are two general switch structures: sliding plate type and swinging rod type. The skateboard switch has a strong sound and feels elegant and comfortable; The pendulum structure has clear sound and low metal impact sound, which is more stable and mature than the traditional skateboard structure in arc extinguishing and service life. 2. Double-hole pressure plate wiring is safer than screw wire pressing. Because the former increases the contact area between wires and electrical appliances, it is oxidation-resistant, not easy to loosen and have poor contact. When the latter screw is strong, it is easy to crush the wire, and the contact area is small, which makes the electrical parts easy to oxidize and age, leading to poor contact. At present, good products are connected by double-hole pressure plates.
Material selection of switch socket
Switch pure silver has strong conductivity, low calorific value and high safety performance, but the performance is greatly reduced when the contact is made of copper. The socket is made of tin-phosphorus-green copper sheet, which can get the best strength, toughness, elasticity and other indicators, and it is tens of times more durable than the socket with ordinary brass reed, and the socket is rarely burned by strong arc when inserting the board. Gold-plated spring needle is extremely difficult to oxidize and has stable performance, which can ensure clear and true sound quality and fast and accurate data transmission.
