Silver Electrical Contacts

A Comprehensive Guide 2023

Silver contacts play a crucial role in the functioning of electronic appliances as they serve as the intersection points where components separate and contact each other during opening and closing. These contacts are typically riveted onto the terminals of various accessories using a specialized machine known as a riveting silver point machine. The usage of silver contacts is widespread in the production of electronic appliances, including switches, relays, and conductive circuit intersection points.

To enhance the physical and contact properties of pure silver, silver alloys are commonly used. These alloys consist of silver with the addition of other metals such as copper and nickel. By incorporating these metals, the overall performance and durability of the silver contacts can be significantly improved.

Advantages of silver electrical contacts:

★ Good electrical conductivity: Silver electrical contacts have excellent electrical conductivity, allowing them to transmit current efficiently and reduce resistive losses.

★ Wear resistance: Silver electrical contacts are wear-resistant, can withstand frequent contact and separation, and are not easily damaged or worn.

★ thermal conductivity: Silver electrical contacts have excellent thermal conductivity, which helps dissipate heat and reduce the local temperature increase of the contacts.

★ Stable resistance characteristics: Silver electrical contacts generally provide stable resistance characteristics, which is important in applications that require precise control of resistance.

★ Oxidation resistance: Silver electrical contacts are resistant to oxidation, so they can maintain stable performance during long-term use and are not prone to rust or deterioration.

★ High Temperature Performance: Some Silver electrical contacts types have good high temperature performance and are suitable for applications in high temperature environments.

★ Reliability: Silver electrical contacts provide reliable electrical connections, ensuring stability and long life of electronic devices.

Silver electrical contacts Applications:

Finished silver contacts are generally small and will not be used alone. We usually assemble it with other products to make electronic components. Usually we solder or rivet the silver contacts to the stamped terminals. The main steps are as follows:

1. Place the completed silver contacts and the required stamping plates to the raw materials.

2. The stamping plate is punched and sheared according to the design pattern through the punch machine.

3. The welding machine welds the silver contacts to the stamped plate.

4. Carry out subsequent cleaning and inspection
