Abstract:

Materials used for electrical contacts in switches and relays must have a good combination of electrical conductivity and wear resistance. Electrical contacts are widely made by particulate composites like tungsten reinforced silver, because the silver efficiently conducts current while the hard tungsten provides wear resistance. Even such contacts erode in time causing poor contact and arcing. Another material used for electrical contacts is silver electroplated copper. To recondition these contacts is widely used silver electroplating, which is very expensive. In tlus paper arc done the experimental data of searching to recondition electrical contacts made from silver electroplated copper by vibrating electrode method.
