1. After the socket bottom box is disassembled, clean the inside of the bottom box
First, clean the area where the switch is placed, and try to remove some dust and debris. Generally speaking, the installation of the product is carried out after the woodworking paint is completed, so the bottom box that has been stored for a long time will inevitably have some dust, so these impurities should be cleaned before installation.
2. Power cord processing
Leave a certain length of the wire in the box for later repairs, cut out some wire cores, but do not damage the wire cores, then wrap the wire clockwise around the terminal of the switch socket, and then tighten the pressure head.
3. Three-wire wiring method for sockets
Each wire should be connected to the corresponding socket port, otherwise the wrong connection will cause some equipment to cause black lights or tripping when in use.
What are the types of wall switches
1. Wall switches can be divided into wave switches, band switches, power switches, pre-selection switches, limit switches, etc. according to their use. Different types of switches are used in different occasions.
2. Wall switches can be divided into micro switches, rocker switches, toggle switches, toggle switches, push button switches, and key switches according to their structure. These switches are different in appearance and structure.
For home decoration, switches and sockets are also one of the issues that need attention. Don't buy inferior switches and sockets for cheapness, otherwise it is easy to cause safety accidents and unnecessary loss of appearance. The following editor introduces the wall switch and socket purchase guide and the safety hazards of wall switch plugs.
Wall switch and socket purchase guide
1. Material
Material is the first factor to ensure the quality of switches and sockets. At present, PC material is recognized as the best switch panel material. It has better flame retardancy, insulation and impact resistance than other materials. Therefore, wall switches and sockets are best made of PC material.
2. Appearance
The appearance of the product can also show the quality of the switch and socket. If the surface is smooth and the color is uniform, it is generally a product of better quality. In addition, consumers should also see whether the brand logo on the panel is clear, whether there are burrs, etc.
3. Internal structure
The internal structure of the wall switch socket is preferably made of tin-phosphor bronze, which has the characteristics of good elasticity, corrosion resistance, wear resistance, and high hardness.
4. Humanized design
Now there are night indicator lights on the switch panel, some of which use fluorescent paint for night indication, and some use power light. The power light method is more environmentally friendly and can provide consumers with softer and more comfortable light.
5. Safety certification
The switch socket must pass 3C certification, ISO9000 series certification, etc., and some international brands may have obtained other national and international safety certifications in addition to 3C certification. These certifications are generally on the product surface, packaging or instructions.
What are the safety hazards of wall switch plugs?
1. If the plug is damaged, it should be replaced in time to avoid short circuits and problems such as combustibles.
2. The switch hitting the wall will cause the outer insulation layer to be damaged, which will cause a short circuit.
3. If the power of the household appliances and the sockets used does not match, if the temperature is too high for a long time, it will cause a fire.
4. The wall switch should be installed away from flammable materials.
4. When using ordinary switch sockets in the bathroom, it is easy for moisture, acidity, etc. to cause short circuits in the switch sockets.
The frequency of using electrical appliances in life is increasing, so we also need to pay attention when choosing sockets. There are many things to pay attention to when choosing sockets. Among them, the 118-type wall switch socket is a common one. So how to install the 118-type wall switch socket? Let's take a look at the relevant knowledge introduction of the 118-type wall switch socket!
How to install the 118-type wall switch socket
1. Prepare the socket to be installed and the connecting wire. Three connecting wires of three colors are required. The same applies to "three-bit" and "four-bit".
2. Distinguishing the live wire, neutral wire, or ground wire by color is a specification and standard, but it is not dead. The only thing to note is that L, N, and ground wires must correspond one by one.
3. The three-wire three-color correspond one by one, which is clear, intuitive, and standardized. 4-bit sockets and nine-wire three-color correspond one by one. In this way, you can ensure that each socket is connected
4. Next, insert the incoming line (incoming line) into the L, N, and ground wire holes according to color.
5. Finally, tighten the screws of "each wiring hole" with a screwdriver in sequence until the wire cannot be pulled out.
6. Then, fix the socket to the dark wire box with M4 screws.
Advantages and disadvantages of 118-type wall switch socket
Advantages:
118-type wall switch sockets can be combined at will, which can facilitate the user's use. In the installation and use, it is necessary to pay attention to the mutual interference between strong and weak electric functional parts. If you have any questions, you can consult the manufacturer and professional technicians.
In appearance, the 118-type wall switch socket is long and strip-shaped, and it is also divided into large, medium and small types, and there are other functional parts. Switches, sockets, telephones, TVs, computers and panels can be combined at will.

The remote control wall switch not only has the function of a switch, but also replaces the traditional wall switch while controlling the indoor lighting. It is an indoor lighting control system that can be flexibly configured. Ordinary users can achieve perfect lighting results with only economic investment.
1. The switch socket has strong anti-interference ability and high reliability.
2. Provides manual and remote control modes, which not only enhances convenience but also inherits the original habits.
3. The single-wire wiring method can not only replace traditional switches, but also meet the electrical and electrical construction standards.
4. Full on and off function, when you are resting, you can turn off the lamps with one click. When using the scene function, you can also turn them on with one click.
5. Millions of sets of non-duplicate code recognition technology to ensure no interference. There is basically no duplicate code phenomenon in the same city, so there is no need to worry that the neighbor's remote control will control your own lamps.
6. Non-directional long-distance partition wall control function. Infrared remote controls are generally limited by spatial distance and direction, while remote control wall switches using wireless radio frequency technology have no such restrictions at all. Generally, signal coverage can be achieved within a radius of 20-100 meters, and can penetrate 2-3 walls.
7. Intelligent learning code matching technology. People habitually believe that the remote control wall switch and the switch are one-to-one corresponding and cannot be changed. However, after adopting the intelligent learning code matching recognition technology, the remote control and the switch can be configured separately, eliminating the interference of the remote control and the switch cannot be separated, and the lighting control can be flexibly performed.
1. The principle of the wall switch
The wall switch realizes the opening and closing of the circuit by opening and closing the switch contacts, thereby controlling the switch of electrical equipment such as electric lights. The switch contacts isolate the two circuits. When the switch is turned on, the circuit is connected, the current path is formed, and the equipment works; when the switch is turned off, the circuit is interrupted, the current is interrupted, and the equipment stops working.
Wall switches are divided into single-control switches, double-control switches and three-control switches. Among them, the single-control switch controls one lamp or one socket, the double-control switch controls two lamps or two sockets, and the three-control switch controls three lamps or three sockets.
2. Classification of wall switches
1. Classification by structure: manual switch (ordinary switch, touch switch), remote control switch.
2. Classification by control object: single-control switch, double-control switch, three-control switch.
3. Classification by function: ordinary switch, delay switch, sensor switch, etc.
III. Precautions for installation of wall switch
1. The wall switch should be installed at the starting position or end position of the circuit, the switch input end is connected to the power supply, and the output end is connected to the load.
2. The installation position of the wall switch should be reasonable to avoid environments such as oil smoke, water vapor, and mold that affect the service life of the switch.
3. The installation of the wall switch should comply with relevant safety regulations to avoid safety accidents such as electric shock and short circuit.
IV. Common faults of wall switches
1. The switch is not working: the reason may be poor circuit contact, oxidation of contact parts, etc., and the contact parts need to be checked or replaced.
2. Switch failure: the reason may be mechanical failure, control circuit failure, etc., and the switch components need to be checked or replaced.
3. Switch tripping: the reason may be excessive circuit load, short circuit or line aging, etc., and the circuit fault needs to be checked and eliminated in time.
In short, the wall switch is a practical and common electrical device. Mastering its principles, classifications, installation precautions and common faults is the basis for use and maintenance.
