Microswitches rely on internal metal contacts to connect and disconnect circuits. The contact material is a core factor determining the overall performance of the switch, directly affecting conductivity, oxidation resistance, arc resistance, and overall lifespan. Among numerous contact solutions, Pure Copper Rivet-Type Contacts have become a common solution for entry-level products due to their low raw material cost, and are also the basic benchmark for comparing the performance of precious metal contacts in the industry. During the R&D and selection phase of various switches, these copper riveted contacts are used as a benchmark sample to test their conductivity under normal operating conditions, thereby differentiating the performance differences between high-end and low-end products.
Round Head Metal Copper Rivets have the fundamental advantage of being compatible with simple equipment. The raw materials are readily available, the processing technology is simple, and the unit cost can be effectively controlled during mass production. They also have good adaptability to low-current, low-frequency operating scenarios. In devices requiring only occasional switching and with extremely low power loads, the conductivity of this type of contact is sufficient for basic use, eliminating the need for additional expensive precious metal plating. Therefore, it is widely used in simple civilian products where durability requirements are not stringent, making it the mainstream choice for low-cost devices to achieve circuit switching functionality.
However, in humid, oily, or frequently start-stop environments, the performance limitations of Custom Red Copper Solid Rivets become fully apparent. Copper is chemically reactive and easily oxidizes and blackens upon contact with air and moisture. The oxide layer increases contact resistance, leading to persistent poor contact. The arcing generated by frequent switching also rapidly erodes the contact surface, resulting in intermittent connections and jamming after tens of thousands of presses. In corrosive environments, its lifespan is further shortened, making it unsuitable for equipment requiring long-term stable operation.
In stark contrast to copper rivet contacts, silver composite contacts are the mainstream choice for industrial and high-end equipment, offering superior oxidation resistance and arc resistance compared to Copper Rivets for Switches. Silver contacts offer lower contact resistance, stable current transmission, and are less prone to overheating. They don't easily develop an oxide barrier layer over long-term use, and exhibit no significant burning even after hundreds of thousands of high-frequency switching cycles. They maintain stable conductivity even in humid outdoor environments with high-current switching, making them perfectly suited for demanding equipment such as industrial control systems, automotive applications, and precision instruments.
From a long-term cost perspective, simply relying on Rivet-type Solid Copper Contacts to reduce the procurement budget can actually increase after-sales losses. Many mass-produced devices frequently experience button malfunctions and unstable circuit contacts, the root cause of which is the use of copper rivet contacts instead of silver composite contacts. While the initial purchase price difference is limited, the overall costs of later repairs and product returns increase significantly. For high-frequency, outdoor, and industrial applications, using precious metal contacts is more economically efficient in the long run.
There are significant misconceptions in the market regarding contact selection. Many low-priced products labeled as having silver contacts are actually only thinly silver-plated. After the plating wears off, the internal substrate is essentially the same as Solid Copper Rivet Contacts for Switches, negating the durability advantages of precious metal contacts. Standard long-life equipment uses thickened composite silver contacts with a compliant silver layer thickness, capable of withstanding long-term arcing and oxidation corrosion. When purchasing, it's crucial to distinguish between plated silver and solid composite silver to avoid buying imitation precious metal contacts and ensure long-term equipment stability.
The selection of contact materials can be clearly categorized according to the usage scenario. For simple civilian products with low-frequency intermittent use and limited budgets, Copper Rivet Contact Elements can be used to control production costs. If the equipment requires high-frequency pressing, humid outdoor conditions, continuous industrial operation, or high-current loads, composite silver contacts must be selected. Matching contact materials to operating conditions avoids losses from frequent failures and controls hardware procurement costs within a reasonable range, which is the core principle of switch structure design and component selection.
To meet the production needs of low-frequency, low-cost devices such as toys, simple lamps, and small household appliances, we have independently developed and mass-produced standardized Pure Copper Electrical Contact Rivets. These contacts feature stable material purity, mature stamping and riveting processes, and a full range of sizes to accommodate various tactile and micro-switch assemblies. Bulk orders offer competitive pricing, precisely matching the production and procurement needs of low-cost consumer products while balancing basic conductivity with cost control.
