Facing the mixed construction market, the choice looks similar, but the quality of the switch panel directly determines whether the household electricity is safe, and whether the choice is reasonable will affect the quality of life. And now most families have babies, so you need to be cautious when buying switch panels.
The switch panel includes switches and sockets for lighting equipment. Before panel installation, the bottom box needs to be installed, and the bottom box should be embedded according to the design drawings, and the panel specifications should be purchased according to the size and use requirements of the bottom box. What factors should be considered in the selection of switch panel? Which brands are worth considering?
As mentioned earlier, the switch panel includes switches and sockets for lighting equipment. There are many ways to start the switch of lighting equipment: cable switch, rotary switch, flip switch, button switch, rocker switch, touch switch and so on. This needs to match the specific usage habits and the requirements of lighting equipment.
It is important to embed the bottom box in front of the panel. In view of the various panel sizes of lamps switches and sockets, it is necessary to embed the bottom boxes of corresponding specifications in advance according to the design drawings. Embedding the bottom box is also important. Don't choose inferior materials, which will affect the installation and long-term use of the panel in the later stage. The following are some approximate data required for the switch panel to be embedded in the bottom box. Comprises a switch and a socket of the lamp device.
① According to the standard size, it is divided into 86 types (86mm×86mm), 1 18 types (1 18mm×74mm) and 120mm×74mm).
The above is the general data of the bottom box. There are also many specifications for the selection of lighting switch panels. Most of the embedded bottom boxes are of type 86 (86mm×86mm). However, the selection of the main position of the switch of lighting equipment is complicated and needs the attention of the owner. The following are the common control positions of the lighting switch panel. It is not recommended to select the switch panel of lighting equipment with more than four control positions.
1 single control/1 double control, 2 single control /2 double control, 3 single control /3 double control, 4 single control /4 double control.
② Switch panel selection:
1, most of the materials that make up the panel are PC materials, commonly known as bulletproof glue. (The English name of polycarbonate is PC, which is an amorphous thermoplastic. )
2. See if the surface of the surface switch is smooth and shiny, and products with burrs are definitely not good;
3. The switch with peculiar smell indicates that the material of the product is harmful to the body because it contains other chemical components. Good PC material is tasteless.
4. Look at the general situation of internal materials. The copper part inside the switch is made of red copper; Compared with the socket, you can see it more clearly. The copper parts inside the socket are made of tin, phosphorus and copper by one-time die casting, which has good conductivity and heat dissipation. Tin phosphorus copper is the most powerful one, with high strength, good conductivity and difficult deformation. (For example, the schematic diagram of Simon's copper products below). So the contrast is understandable. Look at that.
5. When bending and twisting the switch panel, look at the toughness of the product. The switch with good toughness will not crack after installation. Cracking will occur when installing screws with poor toughness.
③ Supporting structure:
The bottom of the switch has a bracket structure to increase its compression resistance. The bracket is divided into steel frame and PC. First of all, PC material can be flame retardant and insulating, and its compression resistance is lower than that of steel frame. The PC material structure is light. The steel frame is directly used as the underframe. Although there is paint on the surface, it is easy to rust once it falls off after a long time, which poses a safety hazard.
(4) Switch contact:
When we use the switch, we can hear the sound, which is produced by two pieces of metal or metal balls. This is caused by contact. If the contact is not safe enough, it is easy to produce arc, which will cause short circuit of the switch and cause danger. High-quality switches are generally made of shock pure silver, with low resistance, soft texture, low melting point, easy oxidation, easy arcing, burning wires or switching elements, resulting in poor power supply. Inferior switches, using copper or iron silver-plated contacts, cut corners and have great security risks. With the development of science and technology, most people choose silver alloy as electric shock. Silver alloy has the advantages of low resistance, wear resistance, high melting point, oxidation resistance and better comprehensive performance than pure silver. Be sure to pay attention to this detail when choosing.
⑤ Common switch brands and their advantages:
Siemens
Switch socket characteristics
1. Impact resistance, high temperature resistance, good surface finish and easy cleaning.
2. Vision, agility and other three series.
3. The socket is made of high-grade elastic phosphor bronze, which has good elasticity and stable plugging and unplugging.
TCL- legrand
Switch socket characteristics
1. It has three price points: high, medium and low, and has nearly 20 switch socket series.
2. Children's locks and other functions to protect children are also unique.
3. Energy-saving and environment-friendly fluorescent design, which can display the position of the switch at night.
the tailor's
Switch socket characteristics
1. subtle and light, simple and generous.
2. The bayonet panel, the frame and the function keys are all clamped, which will not be reversed, and it is not easy to scratch and damage the wall when disassembling. Strong flexibility and variability.
3. High cost performance, suitable for factories, houses, campuses, offices and shopping malls.
bull
Switch socket characteristics
1. The service life is long. The national standard requires the socket to be pulled out normally for more than 40,000 times, and the internal control of Bull requires 80,000 times.
2. Bull switch socket panel is made of imported flame retardant PC material, which will not crack and fade after long-term use, with high safety and long service life.
3. It has high safety performance, and is one of the earliest switch socket brands using lightning protection technology in China, which has realized the protection function of blocking high voltage, strong current and ultra-high temperature generated by lightning.
abb
Switch socket characteristics
Abb's most competitive products are low-voltage switches, especially various series of wall switches.
2.ABB's switch sockets are mainly middle and high-grade, and the products are first-line products both in appearance and internal quality, so the price is somewhat high.
3. The switch socket is fashionable in appearance, elegant in lines, simple and generous, and beautifully decorated.
Goose goose
Switch socket characteristics
1. The quality of the old brand is good, and the price and panel material do not change color, but some series designs are weak.
2. the price is civilian.
3. The contacts of the switch are made of composite silver, which is essentially different from ordinary pure silver contacts. Silver composite silver contact can not only improve the temperature resistance, conductivity and wear resistance, but also effectively reduce the arc that may occur during the switching process, which is more safe and durable.
6. Daily maintenance of switch panel:
Usually, people pay little attention to the maintenance of switches in their daily lives. Many people or children at home will make some small mistakes, such as repeatedly switching on and off. This will not only increase the power consumption, but also reduce the service life of the switch. During the opening and closing process of the switch, internal parts will be worn, such as contacts. In order to avoid insensitive switch, it is necessary to reduce some unnecessary switch actions.
There are also some special spaces, such as bathroom and kitchen. The switch can prevent the influence of water vapor and oil stains on the surface of the switch socket, and wall stickers can be added on it, which is also an important measure to ensure the safety of electricity use.
If you want to keep the panel clean, you can wipe it with a rag dipped in alcohol (70%-75% concentration) instead of water, which will not only leave water marks, but also the danger of electric shock. In order to improve safety, it is best to wipe it after the power is cut off, because alcohol volatilizes quickly and the power cut-off time will be short.
