The image above showcases a commonly used grounding finger spring product. It emphasizes its conductive grounding performance, hence the structural design enhances the reliability of contact with the mating surface. It is suitable for grounding applications on large equipment enclosures, such as shielded windows and doors in shielded laboratories, and shielded compartments. Due to the structural complexity of various electronic devices and products, Eimers has developed a series of grounding spring products with various modified structures in addition to the standard types. Here's a brief introduction.

Vertical ground contact finger spring, designed for applications where the ground contact surface is perpendicular to the mounting surface.

Vertical misalignment type grounding finger spring, applied in scenarios where the grounding mating surface and the installation surface are both vertically aligned and misaligned within the horizontal plane.

In terms of materials, the Grounding Finger Spring Series is made entirely of high-performance beryllium copper, boasting exceptional conductivity and mechanical tensile strength. It ensures stable performance under extreme temperature conditions. Additionally, the surface of these springs is subject to customized electroplating treatments to meet customer requirements.

Surface compatibility requirements, such as bright nickel, bright tin, and zinc chromate plating, etc.

The primary characteristics of the grounded finger spring:

• The structural design has enhanced the reliability of contact with mating surfaces, ensuring electrical grounding performance.

• Grounding applications for large equipment enclosures

• Vertical-type grounding spring strips for applications where the grounding mating surface is perpendicular to the mounting surface.

• Vertical misalignment type grounding finger spring, applied in situations where the grounding mating surface and installation surface are both vertical and misaligned in the horizontal plane.

• Entirely manufactured with high-performance beryllium copper materials

• Offering customized processing for various electroplating techniques to meet customers' surface compatibility requirements
