CONTACT PROFILES

Introduction
Contact profiles are extremely precise Wires for setting up contacts which are mainly used for switching and leading currents. Their capacity ranges from low currents up to currents of 150 A. The materials and profile geometries are tailor-made to customer specific requirements according to their application. When the contact profile wires are manufactured, a hot cladding process is used to join different wires together metallically; profile rollers give them their final shape. Contact profile wires are used in the automotive sector, in Telecommunication, Industrial electronics/control technology, low-voltage technology and large electrical domestic appliances (Washers, fridges etc.) as Relays, contactors, switches, push Buttons and regulators. The complete development of contact and composite materials is an important contribution to the ongoing process of miniaturisation and cost-saving with electromechanical components. Characteristics for the selection of the correct contact profile and material are the material properties, design parameters, switch loads and the required amount of switching operations of the component. The required functionality of the component is achieved through the high standard of knowledge of our qualified employees about the application and processing of different materials. Our Key Competences are individual consultation and experience in design and dimensions of profile geometries, use of suitable materials and specific savings of precious metals. The results of in-house developments and cooperation in international research projects are further pre-conditions for continued product improvement – to your advantage. Please contact us. We are ready to help.
