Product Introduction
Copper stamping contact for electrical switch is the core functional carrier for electromagnetic drive and circuit switching in relays, contactors, circuit breakers, and various low-voltage electrical appliances. Unlike general structural components, this type of component requires a reliable connection between milliampere level control current and kiloampere level load current, maintaining stable performance under the dual tests of mechanical life (millions of operations) and electrical life (on load breaking).
key parameters
Conductivity
The conductivity of Copper stamping contact for electrical switch is ≥ 97% IACS, which is much better than brass and bronze, and can minimize current transmission loss and contact temperature rise, avoiding the risk of equipment overheating.
Mechanical properties
The Brinell hardness of the Stamping copper sheet is 35-45HB, with a tensile strength of 200-300MPa. It has good toughness and formability, and is suitable for complex processes such as stamping, bending, and punching. At the same time, it meets the fatigue resistance requirements for long-term on-off.
Process adaptability
Purple copper has excellent ductility and can be processed into ultra-thin pieces of 0.1mm to Custom copper stamping with a thickness of over 10mm. It balances lightweight and structural strength, perfectly matching the compact space design of switches/circuit breakers.
Core customization items
Structural customization
Metal stamping parts electric copper with various structures such as flat plates, bends, irregular shapes, and porous positions can be customized to adapt to different internal layouts of switches/circuit breakers.
Material customization
Surface treatment options such as silver plating and tin plating can be provided on Copper sheet metal fabrication based on purple copper to improve corrosion resistance and contact life.
Parameter customization
Core parameters of Copper stamping parts, such as thickness, dimensional accuracy, conductivity, etc., can be customized to meet special working conditions.
Application scenarios
Electromagnetic system connection
Copper stamped components are the core connecting components of electromagnetic circuits for contactors, relays, and circuit breakers, mainly used as coil leads and electromagnetic circuit connectors.
01
Main circuit conductive contact
In the main circuit of circuit breakers and contactors, Copper stamping processing connecting is processed into key structures such as dynamic and static contact bases, conductive bridges, busbars, etc.
