Information

The biggest advantage of silver contacts is to increase the frequency of use of the conductor, increase the contact effect, and enhance the performance of the conductor. Silver contacts are widely used in the production of electronic appliances, such as switches, relays, thermostats and intersection points in conductive lines, etc., and silver riveting machines are mainly used to rive them on the terminals of various accessories.

So many things in our lives have silver contacts. Silver contacts and other original accessories are widely used in various high and low voltage electrical appliances, electronic appliances, boat switches, power switches, relays, circuit breakers, sensors, controllers, starters, contactors and other fields.

For switches, the larger the silver contact, the thicker the silver layer, the larger the load on the switch, the safer it is, and the longer the switch life.

The oxide layer of the silver contact not only has good electrical conductivity, but also reduces to metallic silver during use, so it is not necessary to repair it.

More information

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.
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.
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.
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?
