At present, there are various kinds of switch sockets on the market, and the various types of products are of different quality, so that consumers are at a loss when choosing products. The switch socket is not only a kind of home improvement functional product, but also is the main component of safe electricity. Its product quality and performance materials are Preventing fires and reducing losses have a crucial decisive role.
What are the types of switch sockets?
The switches and sockets involved in the home are: commonly used switches, power outlets, information outlets, and panels.
Commonly used switches: According to the number of buttons on the switch, divided into one open, two open, three open, four open switch, and a number of single control and multiple dual control.
Power outlets: Household outlets generally have 10A, 16A, 16A for high-power electrical appliances such as air conditioners, 10A for general appliances.
Information sockets: TV sockets, audio sockets, telephone sockets, computer sockets (information sockets), etc.
Panel type: blank panel, if the panel position is left but not installed temporarily, you can use the blank panel first, and then change the panel you need; switch splash box, socket splash box, can be in the bathroom or easy to splash water Local installation protects the switch socket from being splashed with water.
Switch and socket purchase method:
Method 1: Eyes
Good product appearance is flat, no burr, peak, color and smooth, imported high-quality PC material, good flame retardant performance; some products, although the surface is smooth, but the color is pale, coarse texture, such materials are not good flame retardancy, to Household electricity buried fire hazards.
Method 2 : Manual
A good product panel is difficult to remove directly by hand, and must use certain special tools. When selecting, use the index finger and thumb to press the cover diagonally to the end point. Hold one end at a fixed position and press at the other end firmly. The cover is loose and subsidence. The quality of the product is poor, but otherwise the quality is credible.
Method 3: Ear Listening
By tapping the switch function part, the slower the slide-type sound is, the smoother the feel is, and the better the rhythm is, the better the quality is; the sound is not pure and agitated when opening and closing, and the sound with mid-stream intermittent state is of poor quality.
Law 4: Look at the structure
1. There are two kinds of switch structures that are more common at present: sliding plate type and pendulum bar type. The skateboard-type switch has strong sound and elegant and comfortable feel. The pendulum-type sound is crisp and has a slight metal impact sound. It is more stable than the traditional skateboard-type structure in the elimination of arc and the service life is mature.
2. The connection of the two-hole pressure plate is safer than the screw pressure line. Because the former increases the contact area between the wire and the electric device, it is resistant to oxidation, and is not prone to loosening or poor contact. The latter screw is likely to crush the wire when it is strong, and the contact area is small, which makes the electric part susceptible to oxidation and aging, resulting in poor contact. At present, good products use double-hole pressure plate connection.
Method 5: Selection of materials
Switching sterling silver has strong conductivity, less heat generation, high safety performance, and the performance of copper materials used in contacts is greatly reduced; the use of tin-phosphorous copper sheet in socket materials can be matched with the best strength, toughness, elasticity, etc. Brass reed socket durable dozens of times, and rarely have a strong arc burning socket socket phenomenon; gold-plated spring pin is extremely difficult to oxidize, stable performance, can guarantee the clear and authentic sound quality, data transmission speed accurate.
Method 6: Look at the logo
Currently on the market, the current rating of the general home switch is 16A, the socket current is 10A, and the socket for air conditioners and water heaters is 16A. The good product clearly identifies the available current intensity, while the inferior product has a fuzzy logo and the data is exaggerated. Determine if the marked current rating can be passed safely and without full house smoke.
Method 7: Recognize Brands
Brand-name products have passed the strict tests of time and market and are recognized as safe products in the minds of consumers. No matter if they are materials or quality, they have high-quality processes in packaging, transportation, display, and image design. Brand-name electric products are not only A safe electrician functional product is an artwork that is exquisite, elegant, and reflects an elegant cultural taste.
Switch and socket purchase other precautions:
1, can be set with some switch socket, so that do not have to pull the plug and can cut off the power, not to pull down the wire hanging affect the appearance, such as the washing machine outlet can not be closed when not in use, air conditioning outlet off season off do not pull;
2. Do not install the kitchen socket on the stove top room to prevent overheating;
3, install bathroom Yuba switch, remember to stay a few centimeters more position, because this switch is generally larger than the light switch, if it is a little worse to install into the trouble;
4. Do not install the switch too close to the water. If installed in an open balcony, remember to use a special splash cover for the switch socket.
5, consider the bookcase, cabinet lighting and the corresponding control switch;
6, consider burglar alarm, gas alarm, wall-mounted LCD, entrance lights and other sockets and corresponding control switches;
7, consider the use of sockets in each room vacuum cleaner, extraordinary satellite power outlets, wall-mounted fish tanks, etc., anyway, more than the total reserve socket is not enough to use the off-line plate to solve the more beautiful.
Xiaobian message: Baidu search on the common switch socket brands are the following: Flying Eagle, Siemens, Schneider, Panasonic, Simon, Chint, Longsheng, home, Legrand, Grand. Here I have to say that under the Siemens Vision series recommended by the decoration company nowadays, things are good, but to be true, the authentication method is as follows - the current authentic products are double security, one is scratch coating, 15 security code, Play 400 security phone, there are 20 official anti-counterfeiting numbers on the Siemens switch stand, you can send text messages to check the authenticity, you can also check the official website!
