If you are 4 single-control switches, it is very simple, because there are only 5 wires in it (such as more than 5, it must be to borrow electricity, and now the electrical appliances behind it can not be used, touch the wires, you can find this borrowed wire), measure it with a voltage tester (4:1) If the original wiring is correct, then 4 have no electricity, 1 electric is the main live wire, connect the main live wire to the same part of the 4 switches on the wiring pile, and the other 4 wires are connected to the same part of the 4 switches on the terminal pile, If the control of the lamp position is not satisfied, the 4 wires will be adjusted according to the actual situation.
If you have a dual-control switch inside, also use a voltage tester to measure out 1 electric live wire, connect the main live wire to the middle and middle indirect line piles of 4 switches, because the control line of each dual-control switch has 1 pair, and basically in the same part when entering the junction box, you can carefully pick out 1 pair in the box, each docking to the upper and lower piles of the same switch, not the double control line is still connected to each switch, such as the control of the lamp position is not satisfied, and then adjust according to the actual situation.
If the original wiring is not standardized, the switch controls the zero line, you can replace the above live wire position with the zero line, of course, it is best to replace the fire zero line in the power box, you can still do it as previously said.
In addition, there are only 3 wiring piles for the dual control switch, you say there are 4, then there must be 2 straight-through, use the multimeter to find out, give up one or use it in series.
Because there are only live wires and control wires in the switch, the wrong connection will not damage the circuit. It can be reconnected repeatedly.

Is there a diagram? Or to elaborate, after all, the switches are different, and generally the live wire is connected to the switch. Is there a diagram?

Single control light switch wiring method:
1. Thread the neutral wire directly through the lamp head, and then place the wire on the center point of the switch.
2.Connect the two sides of the light switch with other curves.
3. When the line is outgoing, one is connected to the center point of 220V, and the other is connected to the switch. 4. Finally, check whether the switch can work normally after powering on.
Dual-control light switch wiring method:
First of all, the center point of the double control switch is determined, and the symmetrical Zhuang point is called left and right.
1. Connect the left and right switches in parallel with two wires, one switch is connected to the live wire, and the other switch is directly connected to the control line.
2. Use a wire to connect directly to the center point, connect the other end to the lamp, and check whether the live wire and the quarter line are correctly connected between the switches.
3. It is best to test whether the circuit is correct when energized, and then check whether the lamp can achieve dual control.
4. This control method has potential safety hazards, it is easy to trip, and the whole line will have problems if it is a little jumping.

1. Reserve the two lines of the lamp, one is the zero line, and the other is the control line of the lamp 2, and then connect the two wires into the two interfaces of the lamp, tighten them with screws 3, and then fix the lamp mouth zhidao on the wall and fix it with screws 4, and then there will be two lines for the bit of the switch, one is the red line and the other is the white line, which are the control line of the fire line and the lamp.
5. Then connect the two wires to the switch, note that the red live wire is connected to the L interface, and the white control wire is connected to the L1 interface.
6. Then fix the switch on the wall with screws.
7. Then install the shell of the switch on the switch, so that you can control the light.

The six wires of the single opening are all connected to L1, and the L1 and L2 ends of the double connection are connected. After the power is turned on, no matter whether the switch is in the ON or off position, there is always power at one end of L1 and L2, if there is no power, the switch is broken.
Note: L1 and L2 cannot be connected in series, otherwise the light will never turn on.
2. The zero wire and the grounding wire socket with three wires should generally be grounded.
Wiring method of light switch.
1. "2 holes and one screw lock" is a binding post, a binding post is connected to the fire (the one with electricity in the electric test when the switch is disconnected), and a binding post is connected to the fire (the wire directly connected to the lamp head).
2. There are 3 wires in the switch box, which must be clearly separated before they can be connected. In the switch box of the general family, because it is necessary to connect to the socket, there is a live wire (generally red, the neon tube glows when the electric pen is tested), a neutral wire (generally blue or black), and a ground wire (specified as a yellow and green two-color wire).
3. One end of the switch is connected to the fire, and the other end is connected to the fire (note, both are fire wires), and the fire wire must not be connected to the zero wire or ground wire, otherwise the switch will be short-circuited as soon as it is opened.
To judge the wire that fires, you need to add a section of wire with a multimeter (be sure to confirm, otherwise the consequences will be serious), and use the resistance file of the multimeter to confirm that the wire that is on fire in the switch is connected with a wire of the lamp head before it can be wired.
In addition to the ants, scrapped bicycle inner tubes and rubber gloves were cut into long rubber strips about 1 cm wide, and shoe spikes and pins were used to nail them to the door frame and the window frame between the glass window and the screen window. Since the rubber strip was nailed, no red ants have entered the house. Although the rubber strip cannot completely eliminate red ants, it can effectively avoid the infestation of red ants, so you may wish to give it a try. >>>More
What to do if the walls are moldy? I think many people have encountered such a problem, now I will take a look at the beauty! Many people think that the wall has mold, with a rag to wipe off the mold or repaint the wall can be solved, in fact, this is a wrong idea, this can only be temporarily eliminated or covered, can not be completely eliminated, after a period of time mold will appear again, and more and more serious. >>>More
Before the construction of the wall covering, it is best to check whether the base layer of the wall is strong. If the original wall has problems such as peeling and cracking, the wall should be basically leveled first, and then the appropriate amount of putty with better quality glue should be used to increase its strength, and the wall should be leveled after the wall. Baking soda and white vinegar will cause a large amount of dirt on the inner walls of the gas pipeline to automatically remove and fall. >>>More
You're talking about network cable bars, ** have, to the computer city, where computers are sold, I think the telecommunications bureau should have it, the price is expensive and cheap, there are 1 yuan a meter and 2 to 3 yuan a meter, depending on how you buy it. In fact, 1 yuan a meter is very good. But it's also oh.,You should also pay attention to rest when playing on the computer.,I think your parents are distressed when they see you not resting.。
1. The priority is that the motor lubrication is not good, the shaft part should be lubricated with oil, I was in this situation yesterday, the fan blade is installed on the motor can not be dragged, and after I remove it, the shaft can still operate normally, which shows that the motor is not broken. >>>More
