Electrical Contacts and Contact Materials Wholesalers, Manufacturers & Companies
An electrical contact is a component of the electrical circuit that is located in electrical switches and relays. It consists of two electrically conductive metal parts through which electric current passes or not as they are being touched or separated. The space between them must be an insulating medium: air, vacuum, oil, or other electrically insulating fluid. The contacts can be controlled by a person using pushbuttons and switches, by mechanical pressure in the switches and electromechanical in the relays. The materials of the contacts are usually composed of very good materials conducting electricity, such as silver or gold. Cheaper metals can be used to reduce the costs in the body thickness of the contact with a surface coating with noble metals. The contact arms are typical of strip-like metal to allow movement without breaking. Contacts can be made from a mixture of materials typical alloys including fine grain silver, Silver-Nickel, Silver Iron, Silver Graphite, etc. Whether you are looking for Electrical contacts in large quantity or you want to buy different contact materials to manufacture electrical contacts, eWorldTrade has it all by different manufacturers and suppliers.
