Sometimes I wondered when the switch socket was invented. Did electricity come out when it appeared? If not, how did you use electricity at that time? However, it seems to make no sense to think about these things again. The development and progress of human society is really fast. For hundreds of years, people have all been able to “go to heavenâ€. With the increase of various electrical and electronic equipments in life, more and more people can't do without electricity, and switch sockets that are closely related to electricity consumption are also worth more at this moment. So, how to choose a good socket? First, how to look at the quality of the socket? The rocker is a device for closing the switch up and down. Among them, an important part is called a marble. During the continuous closing of the switch, the marble constantly rubs against the copper sheet, which may cause wear, so the material of the marble is very critical. At present, the material of many brand marbles on the market is ordinary PC material, which is easy to wear. Bull uses reinforced nylon fiber material, hard wear, high temperature, good toughness. 2. Look at the silver contact thickness of the internal copper of the switch The closing of the switch is achieved through the opening and closing of the silver contacts on the copper sheet. The thickness of the silver contacts directly affects the electrical conductivity. The thickness of the silver cover of the ordinary switch is 0.2-0.3mm, and the thickness of the silver cover of the bull decorative switch is 0.4mm. The thick silver coating thickness can effectively reduce the generation of sparks in the switch closure and prolong the service life of the switch. 3, see the thickness and strength of copper Judging the quality of the copper is mainly based on the thickness of the copper sheet. At present, the thickness of many products is only about 0.4 mm. The thickness of the bull's copper sheet is between 0.6-0.7 mm. The thickness of the copper sheet is better and the conductivity is better. The national standard for the number of closures of the switch is 40,000 times. The bull decorative switch adopts a patent pending pendulum technology, which enables the switch to be used continuously for 80,000 times, and the service life exceeds the national standard by a factor of two. Second, the problem with the socket 1, commonly used switch socket size Our common switch sockets are wall switches, which means that the electrical switches and sockets used on the wall are also called type 86 switches, which means that the size of the switch socket is 8.6cm*8.6cm. 2, the fixed screw of the switch socket? The use of long screws? The original purchased switch socket has two matching screws of about 2.5cm, but generally the toilet and the kitchen have to be fixed with a long screw, because the toilet and the kitchen are usually tiled, which increases the thickness. Extended screws are divided into 4 inch, 5 inch and 7 inch. Please consult an electrician for details. 3. What is the difference between a single control switch and a dual control switch? A single-control switch refers to a switch that controls one lamp; a dual-control switch means that two dual-switches can control one lamp (mostly used in bedrooms, stairs). 4, there is a household waterproof switch it? In general, a waterproof cover is added outside the switch. This also greatly enhances security. 5, 10A socket and 16A socket difference? 6, buy switch socket First look at the shell material, then look at the contacts, the third look at the structure, see the protection of the door, the copper material. Switch socket installation is actually at the end of the renovation, do not have to worry about it. Other materials can be bought first, then the decoration master will give a good list of specific, as long as the previous comparison of the brand, quality, cost-effective, etc., fancy and other lists can be purchased directly.
