Start by finding the main switch for the power supply in your home. Generally, the power switch at home is at the door, and the power is cut off when the switch is pulled, and it is in useElectric penTry to see if there is electricity or turn on the electrical facilities at home to see if the power is off, and start our next step after making sure.
1. Find the wire to be connected and distinguish the zero line of fire, the red is the fire line, and the blue line is the zero line. If you don't know, you can try it with an electric pen, one end of the pen light is the live wire, and the other is the zero line. Remember that the live wire is electrified, so don't touch it with your bare hands.
2. The next thing to do is to pinch the thread. After finding the line, use smallpliersOr use small scissors to pinch off the skin of the thread to reveal a long copper wire. Remember that the leaking copper wire should not be too short, otherwise the wiring will not be easy to connect.
A total of four heads have to be pinched off the skin to prepare for wiring.
3. Ready and then wired, connect the two wires of the power supply with the two wires of the lamp head. Don't forget to pinch off the threads of the lamp head. If you buy a lamp head without wires, you can unscrew the cover on the top of the lamp head, two copper screws will leak out, connect the wire to the mouth under the screws, and then tighten the screws.
4. The next step is to fix the terminal with tape, remember to buy insulating tape, which is special for electricians. (If the wire is directly connected to the screw, it will not be fixed with tape). Wrap the connected wire with tape a few times, fix it, and pull the tape tighter and tighter.
5. After connecting, restore the wire to its original place, so that it is for the sake of beautyElectric brakesPush on the power supply, try to turn on the light switch to see if the light is on, if it is on, it means that the wiring is successful, if it is not on, it means that there is an error in the link. If you follow the steps, you won't go wrong.

Yes, first connect the zero wire directly to the bath bomb, and then connect all the second holes behind the switch, and connect the special first hole corresponding to the power supply to the live wire, there should be six other wires left on the bath bomb, and you can insert it directly.

Summary. Add a switch and bulb halfway to the wire, how to wire pro! Hello, glad to answer for you.
Add a switch and bulb wiring method in the middle of the wire as follows: 1. Cut off the power supply, and use a voltage detector to measure whether the wire is live. 2. Connect the L-pillar of the switch to the live wire, and the N-pillar to the neutral line.
3. Connect the L1 post of the switch to one end of the bulb, and the other end of the bulb to the zero line. 4. Turn on the power to see if the bulb will light up, and then cover the bulb with a mask. Hope mine can help you!
Do you have any other questions?
Which wire of the light cable can be connected to the live wire?
Add a switch and bulb halfway to the wire, how to wire pro! Hello, it's a pleasure to answer for you. Add a switch and bulb halfway through the wire and wiring the bulb as follows:
1. Cut off the power supply and use a voltage detector to measure whether the wire is live. 2. Connect the L pillar of the switch to the fire smoldering line, and connect the N pillar to the zero line. 3. Connect the L1 post of the switch to one end of the bulb, and the other end of the bulb to the zero line.
4. Turn on the power to see if the bulb will be on, and then cover the bulb with a mask. Hope mine can help you! Do you have any other questions?

This can be done in the following ways:
1. Different switch connections are different, the general socket bottom box should be 3 wires (live wire, neutral wire and ground wire), live wire-L (red, yellow, blue), neutral wire-n (blue or black), ground wire-e (yellow-green).
2. The socket should be left zero (N), right fire (L), and ground (E), and this wiring method is wired, as shown in the figure below.

There are two wires in the lighting circuit, one is called the live wire, and the other is called the neutral wire. The difference between the live wire and the neutral wire is that they have different voltages to the ground: the voltage of the live wire to the ground is 220v; The voltage of the neutral line to the ground is equal to zero (which itself is connected to the earth).
-
There are three holes on the switch that can be used to connect the switch for double control, if you don't connect to the double control, it is this switch to control the lamp, the connection is: any one of the terminals on both sides of the power live wire switch, the terminal in the middle of the switch is connected to the "live wire control" (output) line on the lamp, and the zero line of the circuit is directly connected to another contact on the lamp, not controlled by the switch.
Remember: the home light switch can not be connected to the zero line, if the zero line is connected, it will still have electricity on the lamp after the switch is turned off, if the live wire and the zero line are into the switch, then the short circuit will occur when the switch is closed, and the danger will occur!。

How to connect the cable of the light switch?
-
A wire can only be used as a live wire, first connect to an interface on the switch, another interface to connect the lead, the other end of the lead wire is connected to an interface on the lamp holder, and the other interface can be directly connected to the zero wire.
-
The power cord is a live wire and a neutral wire, and the neutral wire is directly connected to the lamp head. The live wire is connected to the switch, and the switch is controlled by the fire on the lamp head. That is, it constitutes a loop. As soon as you press the switch, the light comes on.
-
Let me tell you an electrician term, it is like this, "live wire to the switch, zero wire to the lamp head", which means that a live wire directly enters the switch, the wire out of the switch is connected to the lamp port, and the lamp outlet is directly connected to the zero line port line.
-
The power supply is two-wire, a live wire is connected to the switch and the light, and a neutral wire is connected to the lamp, so that it constitutes a loop, and the light can be turned on.
As long as the output voltage does not exceed the input voltage of the oscilloscope, the oscilloscope can measure the output waveform of the switching power supply, but pay attention to avoid electric shock when using the hot bottom plate, and it is best to use an isolation transformer to improve safety.
No, that's not nonsense.
If a double-pole double-throw switch is added to the power supply of the hard disk, it can solve the isolation problem of the two hard disks not interfering with each other, but the danger is extremely great: in the process of operation, once the switch fails or the contact is poor, or the operator mistakenly moves the switch, the two hard disks will be damaged at the same time, or even irreversibly damaged, and the loss will be huge. >>>More
The quality of the miscellaneous power supply is difficult to say, but it can be used.
