Prepare For It Before It Occurs!


Electric arcs based on the property and tendency of electricity to arc between open contacts is a classic thermal source used and that is why it is mainly in welding operations, welding is based on the ionization of the gas between two electrodes and once the gas between the electrodes is ionized, a plasma arc is formed. It could be dangerous and life-threatening, as it can cause fire breaks too. Arcing needs to be avoided in electrical and electronic equipment because not only does it damage the equipment involved and cause a fire.

Why Silver?

Silver, being a white, soft, lustrous, is a ductile and malleable metal having a very high thermal and high electrical conductivity out of all metals, but the high cost of it has stopped us from using it in all electrical devices. Displaying the maximum electrical and thermal conductivity among all metals silver is used in the formation of connectors and the contacts formed from are used in various electrical power circuits, including transmitters, buzzers, currents regulate, and appliance switches.

Why not others?

Silver cadmium contacts and other components are used in electrical devices because they possess two opposing traits. Firstly, they are brilliant conductors of electricity. Secondly, they are also resistant to arc, which means that they prevent the tendency of electricity to arc between open contacts which I highly dangerous and can cause fires.

But for the connectors, this combination of silver in the form of an alloy improves the electrical conductivity due to two reasons, Firstly, on one hand, silver is a better conductor than the other components of the metals and their alloys and, moreover, it has been dispersed in the matrix or in the alloy phases during the internal change in the structure occurring due to the homogenization heat treatment and the isothermal aging of the alloy which would not be this way in case of any other replacements.

An Ultimate Solution

A solution to avoid these problems is the use of silver contacts, electrical silver contact manufacturer has made it easier to get hands-on these electrical silver contacts which are electrical and electrical circuit components found in electrical switches, connectors, and circuit breakers. Each contact is a piece of electrically conductive material, usually a typical metal. When two of the contacts touches, they would pass an electrical current with a certain contact resistance, depending on surface structure, surface chemistry, and especially the contact time, that is when the pair are separated by an insulating gap, that is when the pair does not pass a current. As soon as the contacts touch, the switch is closed; as soon as the contacts are separated, the switch is open. However, the gap must be an insulating medium, such as air, vacuum, oil, etc, preventing the electricity from arcing. These contacts come in various types some common types and varieties all serving the same purpose but are modified and designed according to the need.
