Sunseiki Co., Ltd.
We offer a lineup of highly reliable, cadmium-free contacts featuring exceptional welding and erosion resistance, enabling longer life, higher capacity, and miniaturization of relays and switches. These contacts are widely used in automotive relays and switches, including high-voltage applications for hybrid vehicles (HEVs).
Rivet type electrical contacts
Rivet type electrical contacts are widely utilized across a broad range of applications, from general-purpose to high-load environments. Our lineup includes not only solid silver contacts but also composite silver-saving contacts—produced by cold-cladding silver alloy materials directly with copper or copper alloys. This allows us to deliver high-performance, cost-effective solutions. These products are extensively used in automotive relays and switches, including high-voltage applications for hybrid vehicles.
