Product Description

Silver contact refers to the contact point used to break and close the circuit in electronic and electrical equipment.
Since metal conductor terminals are prone to instant heat and sparks when in contact, silver contacts are thickened or made of polymer metal materials such as copper and silver to improve electrical conductivity and durability.
The advantages of silver contacts include increasing the frequency of conductor use, enhancing the contact effect and improving conductor performance.
Silver contacts are widely used in switches, relays, thermostats, and intersection fulcrum in conductive lines
Silver contacts in AC contactors:
Ac contactor is a commonly used control element in industrial electrical equipment, and one of its core components is silver contact.
The role of silver contacts in AC contactors is to improve the electrical conductivity of the circuit and reduce the contact resistance, thereby reducing the loss of electrical energy and heat generation.
In three-phase AC contactors, silver contacts are usually distributed over three phases, ensuring that each phase has good conductance and heat dispersion condition
Fields of application:
Silver contacts are not only used in AC contactors, but also widely used in high and low voltage electrical appliances, electronic appliances, ship switches, power switches, relays, circuit breakers, sensors, controllers, starters and other fields.
These applications all rely on the excellent electrical conductivity and wear resistance of silver contacts to ensure the reliable operation of equipment 
In summary, the three-phase system of silver contacts in AC contactors is of great significance to ensure the stable operation of electrical equipment by improving electrical conductivity and reducing contact resistance.
