There are many varieties of switch sockets in the market. How to choose the right one? First , We must know that the switch socket can not only play the function of home decoration, but also it can protect the safety of electricity. Therefore, it is necessary to choose special time. Attention. The following Xiao Bian will tell you about how to choose the right home switch socket and the size of the switch socket.
Home switch socket how to choose the right
1, see the structure and appearance
The panel of the switch socket generally adopts high-grade plastic, and the material is uniform. Such a surface looks smooth and has a texture. The panel materials are made of high-quality native PC materials (ballistic rubber), which are excellent in flame retardancy, insulation and impact resistance. And the material is stable, and there will be no discoloration at the same time. The use of switches and sockets made of such materials can greatly reduce the occurrence of fire and other conditions caused by the circuit.
2, see the internal material
The switch contacts use silver alloy contacts to prevent the arc from opening and closing to cause oxidation, and it also has good electrical conductivity. In addition, the wiring is preferably saddle-type wiring, wiring screws plating color (72 hours salt spray), large and good contact surface, strong pressure line, stable and reliable wiring.
3, see if there is a protective door
The security protection door of the socket can be said to be indispensable, so when selecting the socket, the product with the protection door should be selected as much as possible.
4, see the socket clip
Socket clips then the best is to use phosphorus copper, because of good electrical conductivity, fatigue resistance, plug sockets up to 8000 times (GB 5,000 times) is best.
What is the size of the switch socket?
The size of the 1,75-type switch is a commonly used decoration product in China in the 1980s. The electric facilities in that era are not yet very developed. Therefore, the decorative effect of the switch size is not too much emphasis. Simple use is no problem, but If you say that decoration is not enough to make it. The size of the 75-type switch is 75*75mm, and there are fewer and fewer people currently using it.
The size of the Type 2 and Type 86 switches is a national standard. Its size is: 86*86*16.5mm. The center distance of its mounting holes is 60.3mm. Nowadays, switches of this size are used in many areas.
The 3,118-type switch size is a product with a very decorative effect, so it is also used very widely. Its appearance is rectangular, and the size can be freely combined with various functional parts.
Type 4,120 switch size is vertical, there are two main types: one is small: 70 * 120mm; one is a large double type: 120mm * 120mm. The size of the switch type 120 is similar to that of the 118 type. They all belong to the free combination, but the 120 type manual disassembly is more convenient.
