Information

In the switch industry, manufacturers and application companies of a certain scale generally know how to choose silver contacts to ensure the quality and life of the switch, but many small and medium-sized enterprises lack understanding of silver contacts.

A switch with silver contacts to open or close a circuit, break current, or make it flow to other circuits. In the field of silver contact, it is generally divided into pure silver contact, silver nickel alloy contact, silver tin oxide contact, silver cadmium oxide contact and so on.

Composite silver contacts usually refer to the intersection of electrical and electronic components when they are opened and closed, because the metal conductor terminal will simply generate heat and sparks when touched, thereby prompting its contacts to be used. Oxidation and electrolysis only occur in multi-frequency processes

Increase the contact points by thickening, or use polymer metals (more than copper and silver), so contact points made of polymer metals or the same kind of information will increase. The thickened points are called silver contacts.

The main uses of silver contacts are silver, copper, iron, aluminum, etc., and silver plating is usually required to improve its conductivity and avoid oxidation. The content of silver-containing cadmium oxide in the contacts is: 88%, 85%, 40%, 30%, and the cam controller input voltage is not higher than 109% of the extra voltage, and there is no obvious jitter.

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?
