An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers.
Each contact is a piece of electrically conductive material, typically a pair of contacts touch, they can pass an electrical current with a certain contact resistance, dependent on surface structure, surface chemistry and contact time ; when the pair is. Materials used for Electrical Contacts, play an important role in the performance of electrical machines and equipment.
Hence, it becomes quite important to select a suitable material for electrical contacts. The successful operation of electrical contacts for a specific application, is a function of various factors.
While selecting a suitable. Various factors affect the performance of electrical contacts, including tribological, mechanical, electrical, and materials aspects. Although these behaviors have been studied for many years, they are not widely used or understood in practice.
Combining approaches used across the globe, Electrical Contacts: Fundamentals, Applications, and Technology integrates advances in research and /5(2).

"Generation for Generations" is the title of the Basin Electric Power Cooperative year history book, written by North Dakota author Stan Stelter.
A half century ago in Bismarck, ND, Missouri River basin farmers and ranchers set in motion a story that encompasses the themes of self-governance and ownership of electric resources. An electrical contact is an electrically controlled switch that completes or interrupts a circuit affecting an electrical current.
Unlike relays, electrical contacts carry higher current loads and are designed to be directly connected to high voltage feeds. Contacts come in a variety of sizes, from small to very large, depending on voltage requirements and usage.

- 6 p.m. at Compared with Edison, Tesla is relatively unknown, yet he invented the alternating electric current generation and distribution system that supplanted Edison's direct current technology and that is the system currently in use today. Tesla also had a vision of delivering electricity to the world that was revolutionary and unique.
Arcing effects on contacts such as erosion, welding, and contamination are also addressed. Containing nearly 3, references, tables, equations, figures, drawings, and photographs, the book provides practical examples encompassing everything from electronic circuits to high power circuits, or microamperes to mega amperes.
