This type of finger spring product, from the perspective of installation methods, is commonly available in two types: adhesive and clip-on. The adhesive type typically uses PSA pressure-sensitive adhesive as the bonding agent, offering high bonding and shear strength, along with transferability. Moreover, the adhesive finger spring is more space-saving in structure, requiring no additional installation components, making it suitable for narrow space application environments. As shown in Figure 1, the type depicted is a special one from the EMS finger spring series, the foldable finger spring. The structural diagram reveals that the bottom surface of this type of spring extends a sharp angle fold structure, which serves two functions: first, it enhances the compression elasticity of the spring, enabling it to resist greater compression stress; second, it protects the finger structure of the spring, preventing damage from repeated compression and impact. Products with this structural feature are particularly suitable for various applications with frequent opening and closing, such as shielding doors and covers. When selecting, it is recommended to reserve a compression amount between 20% to 60%. Specific size parameters can be referred to in the model size table of Figure 2, selecting the appropriate product according to your needs.

In terms of materials, the foldable finger spring strips are available only in beryllium copper. Beryllium copper springs are high-performance products with exceptional tensile strength and excellent electrical conductivity, as well as high shielding effectiveness. The material itself can withstand extreme temperature ranges, making it suitable for various high-performance application environments. Additionally, to meet customers' requirements for material surface compatibility, this series accepts customization for various electroplating processes, such as bright nickel, bright tin, and zinc chromate plating.
