What are Electrical Spring Contacts?
Electrical Spring Contacts serve as the primary mechanical and conductive bridge inside power relays, miniature circuit breakers, and latching switches, transmitting current under continuous high-cycle flexure. Manufactured directly in our high-precision facility, these spring contacts integrate high-elasticity beryllium copper or oxygen-free copper strip stock with tight micro-stamping tolerances. We supply global OEM and tier-one electrical assemblies with a monthly manufacturing capacity exceeding 15 million units, backed by full material traceability and automated optical sorting.
Material Selection & Contact Structure of Silver Rivet Electrical Connections
Beryllium Copper Spring Base
Beryllium copper is used where one component must provide both electrical conduction and spring action. The material forms the elastic section of the contact while maintaining a conductive path through the relay or switch assembly.
Stamped Spring Geometry
The spring section is produced by stamping and forming. Critical dimensions such as overall profile, mounting area, bend position, and contact location are controlled against the customer's drawing rather than by a universal catalog dimension.
Riveted Silver Contact
For configurations using a silver contact, the contact element is mechanically riveted to the stamped beryllium copper carrier. This separates the spring function from the contact interface and allows the contact material to be selected according to the electrical duty.
Drawing-Based Customization
Custom Riveted Silver Connectors can be developed from CAD drawings, technical specifications, or physical samples. The production route can be adjusted according to the required spring geometry, contact structure, and assembly interface.
Factory Production & Customization of Riveted Silver Connectors
| Drawing-Based Manufacturing | Production can start from 2D drawings, CAD data, or customer samples. This allows the spring profile, mounting structure, and contact arrangement to be matched to the target relay or switch assembly. |
| Stamping Capability | Precision stamping is used to produce repeatable spring profiles and terminal structures. Tooling is developed around the required geometry and production quantity. |
| Contact Assembly | The manufacturing route can combine stamped beryllium copper spring parts with riveted silver contacts where the application requires a dedicated switching contact material. |
| Production Supply | The manufacturing route can combine stamped beryllium copper spring parts with riveted silver contacts where the application requires a dedicated switching contact material. |
Frequently Asked Questions about Electrical Plug Base Alloy Moving Contacts
Why is beryllium copper used for Electrical Plug Base Alloy Moving Contacts?
+
-
Beryllium copper can provide both conductive and spring functions within one stamped component. This makes it suitable for relay moving spring terminals where the contact must flex during operation while maintaining the required electrical path through the assembly.
Can a silver contact be riveted onto the spring?
+
-
Yes. The silver contact is mechanically riveted to the stamped beryllium copper carrier, allowing the spring substrate and contact interface to perform different functions within one assembled component.
Can the spring geometry be customized from a relay drawing?
+
-
Yes. The spring profile, mounting features, bend geometry, and contact position can be manufactured according to customer drawings or samples. Engineering review should confirm the material condition, forming geometry, and critical tolerances before tooling and production.
How are Electrical Moving Contact Rivets inspected?
+
-
Inspection can cover dimensional accuracy, electrical conductivity, mechanical characteristics, and the condition of the riveted contact area.
Can the same stamped spring be used for different relay designs?
+
-
Not necessarily. Relay moving springs are normally geometry-dependent because mounting position, travel, contact location, and spring force vary between mechanisms. A separate drawing review is recommended when adapting the spring to a different relay platform.
