Introduction of key materials for switch & socket

 

Let's take a look at the key materials for manufacturing switch & socket:

1, PC

PC material is also called bulletproof rubber, and its scientific name is Polycarbonate.

Introduction of key materials for switch and socket 1 


Features:
High strength, good impact resistance, strong anti-aging ability, smooth and delicate surface, anti-ultraviolet radiation, not easy to fade, high temperature resistance. It will not deform within 60 minutes under the environment of 100 ℃, and the ignition point is above 850 degrees. It will automatically go out within 30 seconds after leaving the external fire source.
The cover of the JUNON switch & socket is made of PC material, which is durable and does not turn yellow.

 

2, ABS

ABS material is a polymer material composed of acrylonitrile, butadine, and styrene

Introduction of key materials for switch and socket 2

 

Features:
ABS material has the characteristics of good dyeability, good flame retardancy, relatively mature processing technology and relatively cheap price. However, on the other hand,

ABS material has poor toughness, weak impact resistance, short service life and cracks on the surface of the product after long-term use. ABS material is no longer used in switch & socket products of JUNON Company.

 

3, PA66
Commonly known as nylon-66.
PA66 material has high mechanical strength, high toughness, outstanding fatigue resistance, high temperature resistance, corrosion resistance, good insulation performance, and the disadvantage is water absorption.

 

4, Tin phosphor bronze


The product code of tin phosphor bronze is: QSn6.5-0.1
6.5 indicates that the tin content is 6% ~ 7%,
0.1 means that the phosphorus content is 0.1 ~ 0.25%,

Q-bronze,

Sn-tin

Features:
After anti-oxidation treatment, the surface of the current-carrying part is purple-red, which has the characteristics of corrosion resistance, wear resistance, high strength, good electrical conductivity, not easy to generate heat, and strong fatigue resistance.

 

5, Silver alloy contact point

Introduction of key materials for switch and socket 5

Our company adopts silver-nickel alloy material, which overcomes the defects that pure silver is easy to oxidize, soft texture, low melting point, easy to generate arc, contact point is prone to form needle points due to high temperature. And also takes into account the good conductivity of pure silver. The contact point of JUNON company use silver-nickel alloy materials and increase the contact area of the contact point.

 

6. Silver Bridge (Seesaw)

Introduction of key materials for switch and socket 6


Silver-coated copper belt silver bridge: The silver bridge is a key component of the switch on and off. High-quality switches all use thickened and widened silver-coated copper belt silver bridge. The silver-coated copper belt silver bridge is made by combining silver and hardened copper through advanced equipment. Although the thickened and widened silver-coated copper belt silver bridge increases the material cost, it meets the higher requirements for switches of many high-power lamps in modern families.
