Hollow pins are key contact components in sockets with a grounding pin and ensure a reliable protective earth connection. Due to their low weight, optimized bending strength, and the use of low-lead materials such as CuZn37, they offer design advantages over solid pins in modern installation systems.

Contact rivets are widely used contact parts in low-voltage switching devices. This reference article covers design and geometry, common silver-based materials, manufacturing and setting processes, typical applications, and practical selection criteria for engineering and purchasing.

Manufacturing of electrical contacts: materials, forming and joining processes, series stability, quality assurance, and typical failure modes.

The right choice of contact materials determines conductivity, contact lifetime, and switching performance. Learn more about materials and alloys.
