Quality switch and socket panel should adopt advanced plastic products, looks uniform material, smooth surface texture.
Panel material with advanced PC material, its flame resistance, insulation and impact resistance are very good,
and stable material, not easy to change color.
The switch shall be generally used silver contact and a conductive sheet with silver copper composite materials,
which can prevent the opening and closing arc caused by oxidation. Quality of conductive bridge panels using
the silver nickel copper composite material, excellent conductive silver material, and silver nickel alloy arc suppression is very strong,
with brass screw pressing switch, the contact surface is big and good, scoring ability is strong, stable and reliable connection.
