Custom Coil Compression Springs for PCB Touch Button Switches – Accurate, Fatigue-Resistant, Corrosion-Resistant

Product Description

Our custom coil compression springs for PCB touch button switches are meticulously engineered for applications demanding exceptional precision, reliable performance, and long-term durability. Designed specifically for PCB-mounted touch buttons, battery contacts, and other electronic interfaces, these springs provide consistent electrical connectivity, stable mechanical operation, and reliable compression under repeated use. Their robust design ensures accurate response, minimal contact resistance, and long-term operational stability, making them ideal for devices where performance and reliability are critical.

Manufactured using premium-grade stainless steel, copper alloys, or specialized conductive materials, these springs offer outstanding corrosion resistance, high tensile strength, and excellent fatigue performance. This ensures they maintain mechanical integrity and consistent electrical performance even under frequent pressing, high-frequency switching, vibration, or harsh environmental conditions. Each spring is carefully produced in accordance with customer drawings, CAD models, or physical prototypes, with rigorous control over dimensions, coil spacing, wire diameter, tolerances, and compression characteristics to meet exact specifications.

Our advanced forming and coiling techniques allow for precise spring geometry, ensuring uniform contact pressure, optimal electrical conductivity, and smooth compression behavior. This not only enhances touch sensitivity and device responsiveness but also significantly extends the operational lifespan of electronic components. Additional surface treatments such as plating, passivation, or coating can be applied to further improve corrosion resistance, conductivity, or aesthetic requirements, depending on the specific application.

These coil compression springs are highly versatile and suitable for both prototyping and large-scale production, accommodating small-batch custom projects as well as high-volume manufacturing. They are widely used in consumer electronics, automotive touch systems, industrial control panels, battery-powered devices, and medical equipment, providing reliable contact, precise operation, and long-lasting durability across a wide range of applications.

By combining superior material quality, precise manufacturing, and advanced design flexibility, our custom coil compression springs offer a dependable solution for electronics manufacturers, ensuring that every device achieves consistent performance, enhanced reliability, and extended service life. Whether you need springs for innovative prototypes or mass production, our team provides flexible, scalable, and high-quality manufacturing solutions tailored to your specific requirements.
