When we select the light switch, we need to choose the key points. What are the specific points? We will give you a detailed introduction in this respect.

I. Current Carrier of Light Touch Switch (Copper Plate)
1. Brass: It is hard, slightly weak in elasticity, medium in conductivity and bright yellow.
2. Tin-phosphorus bronze: hard, elastic, conductive and red-yellow
3. Red copper: slightly soft, elastic, high conductivity, purple red
2. Touch the switch panel lightly:
1. ABS: Low grade engineering plastics, discolourable, low strength
2. PC Material: Strong impact resistance, strong heat resistance, high transparency
3. Electro-Jade Powder: Flame-proof, color-proof, wear-proof and thermochemical.
3. Touch switch base lightly
1. Imported reinforced nylon: good insulation, strong rigidity, impact resistance, corrosion resistance, high temperature deformation, ensure that internal components never fall off.
2. Recycled PC: Weak impact resistance, weak heat resistance and easy deformation
3. Ordinary synthetic plastics: Aging, flammability and deformability
4. Touch the switch to pull out the nozzle
1. Self-lubricating type: nylon, hard and wear-resistant material, self-lubricating effect, effective reduction of friction
2. Ordinary reinforced nylon: There is astringent band phenomenon in a long time. The increase of friction leads to the melting of silver point and the decrease of carrying capacity.
5. Touch the switch contacts lightly
1. Silver: Low resistance, soft texture, low melting point, easy oxidation, easy to generate arc, burning out wires or switch components, resulting in poor access to electricity.
2. Silver alloys: low resistance, wear-resistant texture, high melting point, oxidation resistance and comprehensive properties are superior to pure silver.
