For the socket, the first thing to consider is its safety. For products with protective doors, you can see the inside through the socket. You can’t directly see the metal part inside, but only a plastic sheet. The safety protection door of the socket is to prevent children from accidentally stabbing and causing electric shock when playing. However, the design requirements of a protective door are relatively high for the company. It is necessary to prevent children from being able to poke small objects into the socket, and it is necessary for adults to easily and smoothly insert the plug into the socket. Anyway, there is no brand in the brand I have used. To achieve the best balance between the two!

It is not necessary to choose all 5-hole sockets for household use. If you can make better planning and targeted settings, you can save costs. For some fixed-position dedicated sockets, such as refrigerators, washing machines, range hoods, kitchen treasures, air conditioners, etc., there is no need to buy 5-hole sockets, 3-hole sockets are fine. It is best to check the plug type of the electrical appliance to be purchased in some places where fixed electrical appliances are placed, whether it is a 3-hole or 2-hole plug. If the number and type of jacks do not match the electrical equipment, some of the jack functions are idle, which will cause waste; in addition, the technical requirements of multi-hole sockets are relatively high. If the design is improper and the accuracy is insufficient, it is likely to cause electric shock during use. , It will also lead to mis-insertion.

At the same time, when purchasing 5 holes, pay special attention to the distance between 2 holes and 3 holes. If the distance is too close, it may cause the 2 hole and 3 hole plugs to be unable to be inserted into the socket at the same time, so try to choose the distance between 2 holes and 3 holes as far as possible of.

The model sizes of switch socket panels are 75, 86, 100, 118, 120, and 146. Part of Jiangsu and Zhejiang provinces are used to using type 120 panels, while most areas of the country use type 86 panels. 86 is an international standard, and type 120 panels are generally installed in a modular manner. The specific choice can be based on personal preference. In addition, most of the panels of major international brands are of type 86, while some of the newer brands in Jiangsu and Zhejiang have more varieties of type 120, and there are also 86 types. Generally speaking, the function of the panel should be concise and clear, and the function should be clear and the installation standard is 86 type. If you like flexible combination, you can use the 120-type modular installation, but it must be assembled in specifications.

One, the switch should be 130~150cm away from the ground, 15~20cm away from the frame edge, and cannot be installed behind the door. The position of the wall switch with the wall panel is at least 0.2MI above the top of the board, the height of the exposed socket is not less than 1.3m from the ground, and the installation socket is not less than 0.3m. The kitchen and bathroom are determined separately. Do not install it on the bedside or on the desktop, and the closing direction of all switches must be the same.

Second, bathrooms and balconies must be equipped with splash-proof sockets or waterproof boxes. They cannot be installed above bathtubs, faucets, and stoves, and cannot be installed 20cm around the gas meter.

Three, household appliances use two-hole sockets rigorously. The power of the Yuba switch is large, and more places are needed. The electrical appliances that often need to be plugged and unplugged can be used with switch sockets.

Fourth, calculate the load, the socket without a fixed load is calculated as 1000 watts, and the ordinary socket uses 2.5 square millimeters of copper core wire.

5. Connect the ground wire on the three-hole socket to the neutral wire on the left and the phase wire on the right; the neutral wire on the left and the phase wire on the right of the two-eye socket.

Sixth, it must be firmly installed and the joints tightened.

Seven, make sure that all wires are fully in contact with the terminal posts of the switch and socket rear seat during installation.

Eight, the switch is mostly opened and closed with the opposite hand, the right hand is more than the left hand, usually on the left side of the door, and the door switch should use a fluorescent type.

Finally, pay attention to protect the panel of the switch socket during decoration to prevent contamination.

1. The height of the switch in each place has certain requirements, unless it is required for special use, the height of the switch is generally between 1.2 meters and 1.4 meters from the ground. The height of the air conditioner varies according to the usage conditions. The switch of the air conditioner is generally above 2 meters, and the height of the floor socket must be above 30 cm from the ground.

2. The position of the switch should be set according to the usage habits of the family. Usually people are used to using the right hand to switch, so the switch is generally on the right side of the door, and a double control switch must be installed on the upper and lower floors of the stairs, which is convenient to use. The room switch needs to be on both sides of the bed.

3. When installing kitchen and balcony sockets, stay away from open flames and water sources to avoid high temperature of open flames from damaging the sockets. In bathrooms or places with water, water vapor can easily enter the sockets, so that the sockets will be short-circuited. Install a waterproof socket.

4. When using high-power electrical appliances, special independent sockets should be used, especially for water heaters and air conditioners. It is best to use three-hole sockets to avoid tripping.

5. When buying a switch socket, you must choose a product with a more guaranteed quality, so that the safety and life of use are more guaranteed.

According to the way of use, it can be divided into: switch type, socket type, switch with socket type;

According to the connection method:

Single control switch, dual control switch;

Single control switch: Several switches are arranged in parallel, each controlling its own electrical appliances, abbreviated as: one open, two open, etc.;

Dual control switch: Two switches can control the same electrical appliance in different positions.

According to the installation method: exposed switch, installation switch, semi-concealed switch, etc.

According to the structure: mechanical and electronic;

Mechanical: Basically composed of hardware and plastic parts, it is a common form of switch socket;

Electronic: with electronic circuits and electronic components, such as dimming and speed control switches, induction switches, and shaving sockets, etc.;

Socket classification: flat plug, square plug, round plug.

Flat plug: China, the United States, Canada, Japan and other Asian and North American countries;

Square inserts: Hong Kong, UK, Singapore, Australia, India, etc.;

Round plug: mainly in some European countries.

Double-open double-control switch is a relatively common form of household switch. Double open means that there are two independent switches, which can control two lights separately. Both on and off are on the same switch panel. Dual control means that two groups of such cooperation can control one lamp without affecting each other. It can be turned on or off on any one of them.

Double opening means that there are 2 independent switches, which can control 2 lights separately. Both on and off are on the same switch.

Dual control means that two groups of such cooperation can control one lamp without affecting each other. It can be turned on or off on any one of them.

Single billing control is an ordinary switch, which can be used at the entrance of ordinary rooms, living rooms, kitchens, bathrooms, etc.

Dual-opening and dual-controlling is not very practical in nature. It is recommended that single-opening and dual-controlling are used to combine the doorway of the bedroom and the bedside to form a set of openings, so that both the door and the bedside can control the light on and off, which is convenient, or there are ceiling lights and wall lights If you need to do 2 sets of switches, then use double-open and double-control, which can realize arbitrary control.

Both dual-open dual-control and single-billing single control are relative terms. That is, there are several switches on the same panel, one switch is called single-open; two switches are called double-open and so on, and there are 3 switches and 4 switches. Dual control or single control refers to the controllable method on each switch. Whether a switch is single control or dual control, the direct way is to look at the number of binding posts on the back of the switch. There are two binding posts on a switch that are single control, that is, one in and one out; three binding posts are dual control, one in and two out, and one lamp can be controlled in multiple places.

Single control means that a light has only one switch. Dual control means that a lamp has two switches (the same lamp can be controlled in different places, such as one door in the bedroom and one at the bedside, while controlling the bedroom light). But the dual control must be designed at the time of wiring. If you have a single-control line, you can’t achieve dual-control even if you buy a dual-control switch. However, dual-control switches can be used as single-controllers, which is a bit wasteful, because dual-control switches of the same specification are more expensive than single-controllers.

Single-open, double-open, and three-open refer to several switches on a switch panel.

Generally, double controls are used in the bedroom, and single controls are sufficient for the living room, kitchen, bathroom, balcony, aisle, and entrance.

The dual control is more user-friendly, which greatly facilitates people who are inconvenient to walk.

Of course, if the house is large, to facilitate the control, the use of dual controls according to the situation can have a convenient and fast effect.

Single-open and dual-control is one of the electrical switch control methods, which can be divided into single-open and single-control, single-open and dual-control, and double-open and dual-control. The single-pole double-throw switch has two functions: one is to control the power output to two devices respectively. The second is that one device can be controlled for different output forms.

There is a saying: single pole double control, single pole double throw;

Single-opening and double-opening, three-opening means that there are several switches on a switch panel.

Single control, dual control means that a circuit has several switch control.

Single-on and dual-control: There is a switch button on each of the two control panels, and the two switch buttons control a circuit at the same time. For example, the lights installed on the stairs can be turned on or off on the stairs, and can also be turned on or off under the stairs.

Single-open and dual-control are literally, there is a switch, both sides are controlled. Example: For example, you have to turn on the light before entering the bedroom, and then turn off the light at the bedside. This requires the use of single-on and dual-control. The light can be turned on and off in two places.
