How to choose a new house renovation switch socket?

Recently, many friends will ask me about the new house decoration. How to choose the switch socket? What brand of switch is safer and easier to use?

How to answer this question, even the experts are very difficult, because there are too many brands of switch sockets, especially the number of brands, famous brands, many famous brands, and each brand has developed high in order to adapt to the market. Medium and low grade products to meet the needs of families at different levels. Comparing the low-end products of well-known brands with the high-end products of the general brands is indeed incomparable.

How to choose a switch socket

So, where do we choose the right switch socket for ourselves? Generally speaking, the insiders look at the quality of the switch socket, nothing more than the following five aspects.

First, look at the brand

Brands must be seen, and for some unfamiliar people, it can be said to be the most important. Because the switch socket belongs to the national mandatory safety 3C certification products, the regular brands have 3C mark, ISO9000 certification mark and so on. Brands that have similar signs and plausible brands and brand names must not be bought. The main problem of these products is the use of poor materials, cutting corners, and even leaving obvious design defects in order to save costs. At the same time, the workmanship is rough, the safety factor is poor, the service life is short, and there are serious safety hazards.

Second, look at the appearance of the panel material

Good switch socket looks carefully, the panel should be smooth and smooth, no bubbles, no scratches, no smudging, uniform color and texture, and it feels heavy. The good panel is made of American PC imported from PC (anti-ballistic rubber). Its flame retardancy, insulation and impact resistance are excellent, which can greatly reduce the fire caused by circuit. The solidity of the base will also affect the use of the switch panel. Some brands now use cold-rolled steel to make this base, which will be more durable.

Third, look at the accessories

Before you buy it, it’s not safe to take it apart. The switch generally uses a pure silver contact (very good conductivity of silver) and a conductive sheet made of a silver-copper composite material, which can prevent oxidation caused by an arc during opening and closing (the ability of silver-nickel alloy to suppress arc is also very strong). The screws in the switch are generally made of copper, with a large contact area and strong crimping capability. In addition, the terminal is also copper, its wiring capacity is large, and is not limited by the diameter of the wire. Of course, copper is best for copper, followed by brass, and copper is the worst. Some small brands are either screw, conductive sheet, copper column shrinkage, or even copper-plated, which has a great impact on the performance of the switch.

Fourth, test feeling

Good switch panel feels very comfortable, the switch button feels light and the sound is crisp, the socket of the socket needs to be equipped with a protective door, the plugging should be lighter, no need to use much force, and when shaking the switch socket, there should be no internal sound.

Five, test component

This is a simpler and straightforward method: a good switch socket should have enough weight. The copper piece inside the switch is the most critical part. If it is alloy or thin copper, it will not have the same weight and quality. Products with a very light weight must be suspected of cutting corners and should be cautious when purchasing.
