Soon after its founding in 1922 Electrical Contacts became the focal world for DODUCO.

Ever increasing requirements on the performance of contacts in electrical switching devices, the need for highly reliable interconnections between electro-mechanics and electronics, the minimizing of precious metal usage and the call for more environmentally compatible materials and manufacturing processes, defined in the past years the development of materials and technologies related to electrical contacts. These latest developments and repeated requests from our customers were the motivation to update the DODUCO Data Book by the Electrical Contacts Wiki. It includes now also materials whose properties and applications are mostly relevant in the North American and Asian markets. We also included materials which are needed for the manufacturing of contact parts and assemblies, but are outside of DODUCO's product offerings. These include contact carrier materials such as copper and nickel alloys, as well as thermostatic materials.

Even so, we felt it was necessary to add more detailed descriptive passages about products and technologies, which expanded the original focus on mostly data tables and diagrams. We updated and re-wrote most chapters of the Data Book. We also expanded and updated the references at the end of each chapter which are meant to aid those readers who want to benefit from more and deeper detailed published resources.

This updated Electrical Contacts Wiki again is meant to be a handy reference and data source for all those who need to work in the field of electrical contacts and their applications. It can however not be a full substitute for personal discussions with experts in electrical contact technology. For such technical exchanges we offer the direct expertise and advice from our application engineers who are ready to answer your questions.

Please challenge us with your unique problems or special requests, because our world is the World of Electrical Contacts.
