panel
Features: 1. High electrical strength; 2. Flame retardant, high temperature resistance, low temperature resistance, suitable for large temperature difference areas; 3. Good impact resistance; 4. Uniform color and oxidation resistance
Performance comparison: Compared with the general switch ABS is easy to oxidize and discolor, the strength is poor, and it is easy to deform at high temperature, but the price is cheaper.
Rear seat
Raw material name: PBT (scientific name: polybutylene terephthalate)
Characteristics: no stress cracking problem compared with traditional insulating materials
Performance comparison: resistivity is much larger than PC
Socket copper
Raw material name: tin phosphor bronze
Features: 1. Strong elasticity; 2. Good fatigue resistance; 3. More than 10,000 insertions; 4. Purple
Performance comparison:
Brass: Brass is soft, easy to deform, and easy to contact for long-term use.
Bronze bronze: soft after processing, hardened after heat treatment, and good performance. Tin bronze: softer. Phosphor bronze: Poor electrical conductivity.
Off function
Raw material name: 1. Silver cadmium oxide copper composite contact; 2. Fatigue resistant spring
characteristic:
1.1 low contact resistance, high allowable current, good electrical conductivity; 1.2. difficult to form oxide film; 1.3. good arc extinguishing performance
2.1 spring elasticity is strong; 2.2 can be operated 80,000 times
Performance comparison: silver cadmium oxide material is not easy to be ablated, bonded, and arc extinguishing performance is better
