Products Description

Our Electrical Switch Socket Silver Contact is a high-performance component specifically engineered for low-voltage electrical systems. It features a robust composite structure combining a brass-stamped base, silver plating, and a precision riveted assembly. The brass base ensures strong structural support and efficient electrical conduction, while the uniformly applied silver plating reduces contact resistance and enhances resistance to arc ablation. The precision riveting process guarantees a secure and durable connection that won't loosen over time.

With over 20 years of expertise in the low-voltage electrical industry, we leverage our vertically integrated manufacturing process and stringent quality control system to deliver reliable electrical contact solutions to customers worldwide.

1. Interface Metallurgical Bonding Strength

Our Switch Terminal Accessories Brass Stamping adopts precision cold-heading riveting or resistance pressure welding technology to achieve metallurgical bonding between the silver layer and the brass substrate. Observation under a metallographic microscope shows that the bonding interface is free of pores and inclusions, with a dense and uniform transition layer. We implement strict shear force testing (usually 20% higher than industry standards) to ensure that the bonding interface will not peel or loosen even under the harshest vibration conditions, fundamentally eliminating contact failure caused by material separation.

2. Coating Thickness and Uniformity

For Electrical Contact Rivets with Brass Stamping, pulse electroplating or selective electroplating technology is applied. We can precisely control the silver layer thickness of the functional contact area (regular range: 2–15 μm, customizable) with a tolerance within ±0.5 μm. Multi-point detection via X-ray fluorescence thickness gauge ensures uniform thickness distribution across the entire effective contact surface, without weak areas caused by edge effects, thus guaranteeing consistent wear tolerance of the contacts throughout their service life.

3. Tolerance Control of Key Dimensions

In addition to regular external dimensions, we pay special attention to the key geometric tolerances of Electrical Contact Riveted Brass, such as the coaxiality of the riveting column and the position accuracy of the silver layer area. For example, the perpendicularity of the riveting column relative to the base plane is controlled within 0.05 mm, ensuring smooth press-fitting into the terminal hole on automated assembly lines and precise alignment with the moving contact. This avoids one-sided contact or uneven contact pressure caused by angular deviations.

4. Consistency of Material Microstructure

We conduct metallographic structure inspection on the brass strip of each batch of Brass Stamping Electrical Silver Contact to ensure that the grain size meets the specified grade (e.g., the grain size of H62 brass is no coarser than 0.055 mm). A uniform and refined grain structure is the foundation for the product's high strength and excellent stamping formability. Meanwhile, we strictly control the purity of silver raw materials (usually ≥99.95%) to minimize the potential impact of impurity elements on electrical conductivity and corrosion resistance from the source.

Customization & Services

Specification Customization

We customize Silver Bimetal Contacts with Brass Stampings of various dimensions according to the junction box depth and aperture of customers' equipment, ensuring precise compatibility with existing devices. By accurately measuring the installation space of customers' equipment and integrating precision machining processes, we guarantee zero gaps and no loosening during contact insertion and fixation. This effectively avoids poor contact or equipment damage caused by mismatched dimensions, enhancing the stability and safety of the entire system.

Material Selection

We offer high-hardness brass substrates or special alloy materials to meet the requirements of extreme working conditions. Special surface treatments such as gold plating and nickel plating are available to improve corrosion resistance. Gold plating gives the contact surface a uniform golden luster, which not only enhances the Bimetal Electrical Contacts Rivets with Brass's aesthetics but also significantly boosts its oxidation and sulfidation resistance, extending service life. Nickel plating endows the contacts with a silvery-white metallic texture and excellent wear and corrosion resistance, making them particularly suitable for humid or dusty industrial environments.

Packaging Customization

We provide anti-static packaging or brand OEM services to meet customers' branding needs. The anti-static packaging is made of professional anti-static materials, with built-in cushioning foam and partitions inside. It can effectively prevent the contacts from adsorbing dust due to static electricity or being damaged by collisions during transportation, ensuring the Electrical Switch Socket Contact Parts are delivered to customers in a clean and intact condition. The brand OEM service can print enterprise logos, product models, production dates, and other information according to customer requirements, helping customers establish a unique identity in market promotion.

Electrical Switch Socket Silver Contact of Different Specifications

Application Scenarios

Relay Static Terminals

The Switch Terminal Accessories Brass Stamping serves as the core static contact of the relay, responsible for stable signal transmission. The silver plating layer features low contact resistance (typically less than 0.05Ω), ensuring accurate and distortion-free signal transmission. The brass substrate, after special heat treatment, boasts excellent high-strength properties (tensile strength ≥ 350MPa), making it suitable for high-frequency switching scenarios with tens or even hundreds of operations per minute in industrial control. It is a core guarantee component for relay modules in industrial automation production lines and smart home control systems.

Wall Switch Accessories

The Electrical Contact Rivets with Brass Stamping acts as the core conductive component of wall switches, undertaking the on-off control of circuits for lighting and electrical appliances in residential and commercial settings. The smooth and dense silver-plated surface can quickly extinguish electric arcs generated at the moment of switch breaking, reducing arc ablation damage to the contacts. The brass substrate, after phosphating treatment, has good wear resistance and can withstand mechanical friction caused by frequent daily switch operations (dozens of times on average per day).

Socket Wiring Terminals

The Electrical Switch Socket Silver Contact is used for internal wiring connection of sockets and power strips, reliably linking power lines to socket panel conductive sheets and undertaking the task of efficient conduction of large currents (usually 10A-16A). The highly conductive brass substrate (copper content ≥ 99.9%) ensures current transmission efficiency and reduces line loss. The low contact resistance of the silver plating layer (thickness ≥ 0.5μm) avoids local overheating caused by poor contact, thereby reducing energy consumption and fire risks.

Industrial Control Switches

In automation equipment and control cabinets, the Electrical Switch Socket Contact Part is used for signal transmission, status indication, or interlock control. These contacts are usually made of high-conductivity silver alloy materials, and their surfaces are subjected to precision plating treatment to ensure stable electrical connection performance even under frequent on-off operations. With a compact structural design, the internal spring shrapnel undergoes special process treatment, enabling it to work normally within a wide temperature range of -40℃ to +85℃.
