What are the functions of silver contacts?
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 cross-point fulcrums in conductive circuits, etc. They are mainly riveted on the terminals of various accessories by using a silver point machine.
So there are silver contacts on many things in our lives. Silver contacts and other original accessories are widely used in various high and low voltage appliances, electronic appliances, rocker switches, power switches, relays, circuit breakers, sensors, controllers, starters, contactors and many other fields. Its shrinking trend also reflects the market trend of downstream industries to a certain extent. Of course, for companies specializing in silver contacts, this may just be a normal rhythm.
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.
For the switch, the larger the silver contact, the thicker the silver layer, and the larger the load appliances that the switch carries, the safer 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 repairs are not required.
