Definition Of An Electrical Contact Point

SHIN SAENG Quality & Research(Q&R) Department has been able to remove disadvantage of the contacts, with many kind of Silver/Cadmium oxide, Silver/Nickel, Silver/Tin Oxide, Silver/Copper/Nickel and Silver/Palladium Alloys, and other precious materials.

The SHIN SAENG METAL’S contact materials have excellent advantages, as following

 ◈ Advantages

   - Higher resistance to welding.

   - Resistant to material transfer

   - More erosion resistant

   - Increase in working life of contacts

 ◈ Some Of Application

   - Low voltage contacts, Motor S/W &  Motor protective switchgear.

   - Low voltage Circuit Breakers

   - Molded-Case Circuit-Breakers.

   - Residual current Circuit-Breakers.

   - Small motors & Lamp Loads.

   - Motor vehicle electrics. 

 Shape Classification By The Name Of The Contact

  1) Solid type : Generally used single metal Electrical Contact.

  2) Clad type : Complex Electrical Contact saving materials of Solid Electrical Contact with considering economics.

  3) Double Clad type : Make easy insertion into the terminal hole in automatic riveting Line.

  4) Tubular type : A Electrical Contact riveted to a fragile material such as bakelite.

  5) Button type : Resistance welding as a contact point with the proper protrusion on the back  of the contact (SPOT) contacts are used to.

Used to weld a spring material or a bimetallic material

  6) Plate(Disk) type : Material of Plate -type contacts Ag-CdO, AgW, AgWC 4 discoid shape , or the like plaque, a special type.

This contact is a Brazing or Spot welding.
