1, panel: (three kinds)
ABS: low-grade engineering plastics, easy to change color, low intensity.
PC material: high impact resistance, heat resistance, high transparency.
Electric jade powder: never burn, never change color, never wear, strong thermochemical.
2, the switch carrying pieces (copper) (three)
Brass: its hard, flexible slightly weaker, medium conductivity, bright yellow.
Tin phosphorus bronze: hard, flexible, conductive brass better, was red and yellow.
Copper: a soft, flexible, high conductivity, was purple.
3, switch contacts (two)
Silver: low resistance, soft texture, low melting point, easy oxidation, easy to produce arc, burn out the wire or switch components, resulting in poor power.
Silver alloy: low resistance, texture wear-resistant, high melting point, anti-oxidation, superior overall performance than pure silver.
4, switch pull mouth (two)
Self-run type: nylon, hard wear material, comes with lubrication, effectively reduce the friction.
Ordinary enhanced nylon: over time astringent belt phenomenon, increased friction led to the melting point of silver, carrying capacity decreased.
5, base (three kinds)
Imported reinforced nylon: good insulation, strong rigidity, impact resistance, corrosion resistance, high temperature deformation, to ensure that the internal components will never fall off.
Recycled PC material: impact resistance weak, heat resistance is weak, easy to deform.
Ordinary synthetic plastics: easy to aging, flammable, easy to deform.
