(Summary description)Silver contacts broadly refer to the intersection of the separation and contact of electronic appliances when they are disconnected and closed. Because metal conductor terminals are prone to instantaneous heat and sparks at the moment of contact, the multi-frequency process in which the contact points are used In this case, oxidation and electrolysis are easy to occur, so the contact point is increased and thickened, or made of polymer metal (copper and silver are mostly two materials), so this contact point made of polymer metal , Or the point that is thickened by the same material is called silver contact.

Information

Silver contacts broadly refer to the intersection of the separation and contact of electronic appliances when they are disconnected and closed. Because metal conductor terminals are prone to instantaneous heat and sparks at the moment of contact, the multi-frequency process in which the contact points are used In this case, oxidation and electrolysis are easy to occur, so the contact point is increased and thickened, or made of polymer metal (copper and silver are mostly two materials), so this contact point made of polymer metal , Or the point that is thickened by the same material is called silver contact.

Features

The characteristics of silver contacts are that it increases the frequency of use of the conductor, increases the contact effect, and enhances the performance of the conductor.

Use

Silver contacts are widely used in the production of electronic appliances, such as switches, relays, and the intersection fulcrums in conductive circuits, etc., and they are mainly riveted on the terminals of various accessories by using a silver riveting machine.

Materials used

The main materials used for silver contacts are silver, copper, tin, nickel, cadmium, etc.

More information

What are the functions of silver contacts? [ 2022-04-12 ]

Are the silver contacts pure silver? [ 2021-07-30 ]

The first step is to prepare the silver extraction solution (acid). The silver withdrawal liquid specifically dissolves the silver dots. The brass matrix and the copper matrix are not damaged, and the copper is sold directly after cleaning.

How to know the quality of silver contacts is good or bad? [ 2021-07-30 ]

The silver contacts used in our switches can be judged as good or bad. The closing of the switch is achieved by the opening and closing of the silver contacts on the copper sheet to achieve the energized state. The thickness of the silver contacts directly affects the electrical conductivity. The thickness of silver coating of ordinary switches is 0.2-0.3mm, and the higher the thickness of silver coating, it can effectively reduce the generation of sparks during switch closing and prolong the service life of the switch.

The resistance of the silver contact [ 2021-07-30 ]

Silver contacts have high electrical and thermal conductivity, low and stable touch resistance, good welding and processing functions. Fine-grained silver contains a small amount of silver in the silver, which greatly refines the material arrangement grains. In the case of almost the same touch resistance, its mechanical strength and temperature resistance are higher than that of silver. Therefore, the solder resistance and arc burn resistance are better than silver.

What are the areas of silver contacts? [ 2021-07-30 ]

In the field of silver contacts, it is generally divided into pure silver contacts, silver-nickel alloy contacts, silver tin oxide contacts, silver cadmium oxide contacts, etc. However, in the switch industry, manufacturers and application companies generally know how to Choose the switch silver contact to ensure the quality and life of the switch, and many small and medium-sized enterprises have a lack of awareness of silver contacts. In the switch industry, silver cadmium oxide and silver nickel alloy contacts are more widely used. , But how much do you know about the ratio and production process?
