Second, to observe the internal structure of switch and socket:

Switch should adopt pure silver contact and usually made of conductive silver copper composite material, which can prevent arc oxidation. High-quality panel of conductive bridge is silver nickel copper composite material with good electrical conductivity,nickel and silver alloy arc control capability is very strong, switch should adopt line pressing with brass screws, wall switch and socket's interface is big and good, pressure ability is also strong,wall switch and socket should usually use stable and reliable connection.

Third, to choose wall switch and socket with safety door:
