What are the functions of silver contacts

The biggest advantage of silver contacts is that they 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 fulcrums in conductive circuits, mainly using riveting silver point machines to rivete them on the terminals of various accessories.

 

So we have silver contacts in many things in our lives. Silver contacts and other original accessories are widely used in all kinds of high and low voltage electrical appliances, electronic appliances, ship-type switches, power switches, relays, circuit breakers, sensors, controllers, starters, contactors and other fields. 


The silver contact used in our switch can judge whether it is good or bad. 


1. The closure of the switch is achieved by the opening and closing of the silver contact on the copper sheet, and the thickness of the silver contact directly affects the conductivity. 
2. The silver thickness of ordinary switches is 0.2-0.3mm, and the higher the silver thickness, it can effectively reduce the generation of electric sparks in the opening and closing and extend the service life of the switch.


For switches, generally speaking, the larger the silver contact and the thicker the silver layer, the larger the load appliance of the switch belt, the safer it is, and the longer the switch life.
The oxide layer of the silver contact not only has good conductivity, but also reduces to metallic silver in use, so it can not be repaired.
