Switch & socket
When the house is decorated, there are dozens of wall switches and sockets to be used. it will not take long for the inferior wall switches to start a fire, which will bring hidden dangers to our lives.
When choosing a wall switch, it is necessary to pay attention to the following three aspects:
First, observe the appearance of wall switches and sockets.
The panels of high-quality switches and sockets should be made of high-grade plastic products, which looks like a uniform material and a smooth and textured surface. Panel materials with advanced PC material, its flame retardancy, insulation and impact resistance are very excellent, and the material is stable, not easy to change color.
II. Internal structure.
The switch should usually use sterling silver contacts and conductive sheets made of silver-copper composites to prevent oxidation caused by arc during opening and closing. The conductive bridge of the high-quality panel adopts silver-nickel-copper composite material, the electrical conductivity of silver material is excellent, but the ability of silver-nickel alloy to restrain arc is very strong, the switch adopts brass screw to press wire, the contact surface is large and good, the wire pressing ability is strong, and the wiring is stable and reliable.
Choose wall switch products with protective doors.
To check the tightness of the wall switch or socket clip, the smooth insertion force is a key factor. At the same time, strong extrusion makes the plug not easy to fall off, which effectively reduces the occurrence of power outage accidents caused by non-human factors. While considering the safety of switches and sockets, their appearance design is also concerned by more and more consumers, and the choice of color is as close as possible to the color of the wall.
Correct and safe use of switch sockets, do a good job of switch socket fire prevention measures to avoid disasters. There are also potential safety risks in the use of switches and sockets.
Electrical appliances mainly get power through switches and sockets, so the use frequency of switches and sockets is very high. However, if the switch and socket are selected, installed or used improperly, it is easy to cause fire accident. Therefore, it is very important to do a good job in the prevention of this kind of fire.
The fire prevention measures of switches and sockets mainly include the following eight aspects:
A, correct selection, that is, according to the total capacity of household appliances and the specific use environment, select the appropriate switches and sockets. Fire-proof switches and cable switches should be used in places with high humidity; switches and sockets should not be installed in rooms with corrosive materials or dust, but should be installed outdoors; in places with the danger of combustion or explosion, fire-proof or explosion-proof switches and sockets should be selected.
B, the knife switch should choose the matching fuse. Arbitrary changes, especially thickening melts, are not allowed, and fuses are not allowed to be replaced by wires such as copper, aluminum, iron, etc.
C, the rated current and voltage of switches and sockets shall be consistent with the actual electricity consumption. Do not overload arbitrarily, lest the overload of the line will burn out the Bakelite and cause short circuit and cause fire.
D, unipolar switch should control the fire (phase) line, can not be connected to the zero line. Otherwise, if the human body touches the stack wire, it will also cause an electric shock accident. Once the fire wire is grounded, there will be a short circuit or even a fire.
E, lamp socket is prone to accidents when it is overloaded. Therefore, high-power appliances such as electric irons, electric stoves and air conditioners should not be connected to lamp sockets to avoid causing fire.
F, when going out, sleeping or a sudden power outage, the power should be cut off in time, especially the electric heating appliances should be paid more attention.
G, switches and sockets should be installed in a dry, clean and dust-free position as far as possible, so as not to cause Bakelite short circuit caused by damp corrosion and cause fire.
H, switches and sockets should be repaired and replaced in time after aging and damage.
For the well-being of you and your family, please use switches and sockets correctly and safely to prevent accidents!
