Silver Electrical Contacts Application Specifications And Contact Burn-out Fault Solutions

Silver Electrical Contacts are critical contact points in electrical and electronic components during opening and closing. The contact between metal conductor terminals generates instantaneous heat and sparks, accelerating the contact operation. In oxidizing environments, contacts are prone to electrolysis, leading to contact thickening. Therefore, high-quality contacts are often made of metals such as copper and silver. Contact points made of copper and silver, or thickened with similar materials, are called silver contacts.

To ensure the performance and lifespan of Electrical Silver Contacts, the following specifications must be strictly followed during use and processing:

The Electric Contacts riveting workshop must maintain a dust-free environment to prevent dust, debris, and other foreign matter from adhering to the contact surface during processing, affecting the contact conductivity.

Pay attention to environmental control at the processing site. Store organic plastic materials separately from contact elements to prevent organic matter from adhering to the contact surface, causing poor contact or contact obstacles.

Riveting operators must wear finger cots and are strictly prohibited from directly touching the outer surface of the Electrical Contact Points layer to prevent oxidation and blackening of the contacts.

The environment in the Silver Electrical Contact Rivets processing workshop needs to be controlled at a temperature of 22~24℃ and a relative humidity of 40~55% RH to provide stable and suitable conditions for contact processing.

To prevent the Electrical Fittings Bi-metal Silver Contact Points from sulfiding and yellowing, opened silver contacts must be used within 12 hours. Unused contacts must be resealed, preferably using vacuum packaging.

During use, Electrical Silver Contacts may generate electric sparks. These sparks can cause the contact surface to become uneven, reducing the effective contact area, which in turn increases resistance and temperature. Daily use requires monitoring the contact condition and timely maintenance or replacement.

In actual use, contact burn-out is a common fault, and its causes and solutions are relatively clear. On the one hand, when the load current flowing through the contacts approaches the rated value, long-term operation can easily cause contact burn-out. On the other hand, contactors and other equipment often carry inductive loads, and the electric arc generated when the contacts open and release can easily cause erosion damage to the contacts. In interlocking control circuits, a single contact may fail to switch states properly due to the relay or contactor operating too quickly. This can be resolved by connecting two or more contacts in series to increase the switching distance, thus extending the switching time. If excessive load current causes insufficient contact capacity and burnout, parallel connection of contacts can be used to expand capacity.

Generally, the causes of contact burnout in electromagnetic relays and contactors are relatively concentrated, and the solutions are clear and feasible. In electrical control circuits, the flexible use of series and parallel contact connections, coupled with high-quality Electric Contacts, can effectively reduce fault occurrences and improve equipment operational stability.
