1. Electrification part requires high quality material, good conductivity, low temperature rise, strong transmission performance, low resistance.

2. Fire proof PC, high fire resistant, anti high temperature, excellent insulated performance; Good electric performance, high dielectric intensity, high rigidity, anti-nick. Widely used in hotel, house and office electric circuitry.

3. The panel and fixing frame take separate structure avoiding pollution when operating.

4. The switches take silver alloy joint.

5. The sockets take phosphor bronze clip and design of anti single-pole insert.

6. The switch contacts are made of high quality silver alloy material, which have a good performance against electric arc and melt weld.

7. The on-off operations exceed 80000times, the socket reach 10000 times.
