Such as a single billing control and a dual control; two open dual control. 2, single control switch: only open here, this side off. One switch controls one lamp, two switches control two different lamps, and so on. 3, dual control switch: It is possible to control a lamp in two different places at the same time. It is necessary to lay a good line beforehand to open this side and close the other side. The single control cannot be used for double control, and the dual control can be used as a single control. 4.Single control switch socket: The control socket can be turned off and on, convenient to use, no need to pull the plug, and can also be used alone as a switch. It is often used in common electrical appliances, such as microwave ovens, washing machines, and individually controlled mirror headlights. 5, dual control switch with socket: with a single control switch with socket function. This switch can also control the lamp on both sides together with other dual control switches. 6. Multi-function socket: It can be compatible with old-fashioned and foreign-style round-pin plugs, square-pin plugs and so on. 7, three-hole socket: three holes are divided into 10A 16A 25A. Commonly used home appliances, use 10A three holes, such as refrigerators, washing machines, hoods, etc.; 1.5P/2P water heaters generally require 16A three holes, vertical cabinet air conditioning 3P needs more than 20A. 8, information outlets: also known as weak outlets, refers to the phone, computer, TV outlets, due to the back end of the plug-in module market price is high, so are more expensive. 9, dual TV, dual telephone, dual computer socket: These are independent wiring, not divided into two. 10, socket wiring: generally now the phone socket is four-core, if the phone line is two core, then the number 2 and 3 (above) can be. If it is four cores, then the corresponding connection. 11. Computer socket wiring: 1 pair of yellow and white, 2 pairs of yellow, 3 pairs of green and white, 4 pairs of blue, 5 pairs of blue and white, 6 pairs of green, 7 pairs of brown and white, 8 pairs of brown. Special wiring tools are required for wiring. The conventional wiring is completed within three times. The wiring cannot be repeated many times, which may cause damage to the computer module. 12, dimming, speed, tuning switch: Now the dimmer switch can only be used in incandescent lamps (ie, light bulbs). Dimming can only adjust the light and darkness.
