Three elements of fireproof wall switch socket:
1, observe the wall switch socket appearance, high quality switch and socket panel is made of advanced plastic products, its material is uniform, the surface is smooth and texture.
2, observe the internal structure of the switch and the suction seat, the switch is made of sterling silver contact and conductive sheet made of silver composite material, which can avoid oxidation caused by arc when opening and closing; The conductive bridge of high quality panel is made of silver nickel copper composite material, silver material has excellent electrical conductivity, and silver nickel alloy has strong ability to restrain arc, the switch is made of yellow report screw press line, the contact surface is large and good, the press line ability is strong, the wiring is stable and reliable.
3, the choice of wall switch products with protective doors, to check the fastening degree of intelligent fireproof wall switch or socket clip, smooth pumping is a key factor. At the same time, the strong extrusion makes the plug not easy to fall off, effectively reducing the occurrence of non-human factors of power failure.
