Why does the indicator light of the socket stay on? Even if you turn off the switch of the outlet, i

It should be that the contacts in the switch have been ablated, causing them to stick together and cannot be separated, even if the switch is closed and separated, the socket is still electrified.

You can try: turn off the switch to see if it can still use electricity, if so, the switch is out of order, it can't be turned off, and the inside is glued. It is recommended to use high-power household appliances as much as possible without switches on sockets, such as:

Electric cookers, electric kettles, electric stoves, etc. Because the switch power that comes with the socket is insufficient and not durable.

It may be that the indicator light is connected to the front of the switch and is not controlled by the switch, or it is possible that the switch controls the inductive electricity generated by the neutral line and causes the indicator light to be always on.

Check whether the switch is broken by the live wire? Please turn off the live wire and try again, check if the neutral wire is in good contact, if the contact is not very good, there will definitely be a light-emitting diode that induces electricity to light up, and if the socket is wet, the light pipe will also be bright.

This situation is because the indicator light of the socket is connected to the power supply, that is, the power end of the switch, if you want to switch, turn off this indicator light and it will not light up, then you only need to connect the line of this indicator light from the power end of the switch to the control end of the switch, that is, to the other end of the switch.

In this case, there is a problem with the connection of the indicator light of your car. You can try it and see if you can continue to use it after turning it off.

It is estimated that the switch controls the neutral line.

Summary. 1. The socket indicator light is generally a neon gun, low voltage or induction electricity can be lit, and the indicator light is on but there are many faults without power.

2. Troubleshooting when the socket indicator light is on but there is no power.

1. Check whether there is a fault in the neutral line of the line;

2. Use the universal transformer to measure whether the line voltage is the normal power supply voltage;

3. Check whether there is a virtual connection phenomenon in the wiring of the line;

4. Check whether there is any fault caused by electric shock inside the power socket.

Why is the indicator light on the socket strip on but not energized?

The lights flickered and flickered, and the socket was dead.

It's possible that the line is broken.

The screws inside the socket may be loose.

1. The indication of the socket board is installed at the incoming wire, if the rear part of the wiring is in poor contact (or broken), it may cause the socket to not be energized.

2. The current and voltage of the indicator light are very small, if the line contact is poor, the electrical appliance cannot work normally, but the indicator light may be on.

The socket indicator is directly connected to both ends of the neutral line of the live wire through a resistor, which can only show that the power supply is electrified. In this case, the two ends of the socket at the rear of the indicator light are disconnected, and they need to be disassembled to check to determine the source of the fault.

Generally, this phenomenon is the internal disconnection of the socket power cord, that is, the oxidation of the broken wire, the indicator light is a break point or a resistance value is not completely disconnected, the only solution is to find the breakpoint, and the brightness of the indicator light will return to normal after connecting.

The socket is a must-have item for the household, so what is the matter with the socket not broken but not powered, let pchouse explain it to you today.

1. Check whether the inlet ends of the wires connected to the sockets from the air switch of the control socket circuit are not in good contact. For example, whether the connecting wire end between the air switch and the socket is falling off or oxidizing, and whether the connecting screw of the thread head is tightened.

2. You can also check whether the air switch has tripped, and if there is a trip, there may be circuit overload or short circuit. So first unplug the many electrical appliances in the house, try to close the air switch, if it jumps, it means that the line has a short circuit, if it does not jump, it means that the line is overloaded or some household appliances are short-circuited, or even leakage.

The internal terminal block is loose, you can open it and solder it.

The first column of the table indicates the number of lemonade glasses that Telma can produce, ranging from zero to 10 glasses per hour. The second column shows the total cost of producing lemonade at Telma. Figure 13-4 plots the total cost curve for Telma.

The amount of lemonade (according to the first column) is on the horizontal axis, while the total cost (according to the second column) is on the vertical axis. Southy? Terma's total cost curve shape versus Hengree?

Helen's similarity. In particular, it becomes steeper as production increases, reflecting (as we have discussed) marginal yield decline.

Fixed vs. variable costs.

The total cost of Telma can be divided into two categories. Some costs do not change with the output of the production and are called fixed costs. Telma's fixed costs include the rent she has to pay, as this cost is the same no matter how much lemonade Telma produces.

Similarly, if Telma needs to hire full-time store staff who pay salaries, the clerk's salary is a fixed cost, no matter how much lemonade is produced. The third column of table 13.2 shows the fixed cost of Terma, which in this case is $3 per hour.

Some of the costs of a business fluctuate as the business changes its output, which is known as variable costs. Telma's variable costs include the cost of lemons and sugar: the more lemonade Telma makes, the more lemons and sugar she needs to buy.

Similarly, if Telma had to hire more workers in order to produce more lemonade, then the wages of those workers would be a variable cost. The fourth column of the table shows the variable costs for Telma. If she doesn't produce it, the variable cost is zero, if she produces one cup of lemonade, the variable cost is dollars, if she produces 2 cups of lemonade, the variable cost is dollars, and so on.

Cause. This is because the neutral line of the socket is broken, because the power of the indicator light is too small, as long as there is a live wire, there is no neutral line will be bright, after plugging in the electrical appliance, the electric zero line is sensed by the circuit of the electrical appliance to the live wire, and the indicator light will not be lit.

Solution: In this case, the broken wire can be replaced.

Hello, the socket indicator light is on, and there is no electricity, which may be the poor contact of the socket line. That's why the lights are on and there's no electricity. Try it out with a different outlet.

It may be inductive electricity and the socket wire is broken.

Summary. Why is the indicator light on the socket strip on but not energized? 1. Why is there no electricity in the socket, but the light is on1. The reason why the light is on, but the socket has no electricity, is mainly because the socket and the light in your home are not the same circuit, so they will not be affected.

If there is a problem with the switch that controls the socket at home, such as a tripping situation, it will cause the socket to have no power, but the light is on. 2. Use a professional voltage instrument to measure whether there is a wiring problem in the socket. If the socket fails, it will also lead to no electricity.

If the wires of the socket have been burned, it will directly cause no electricity inside the socket. 3. Many people's socket wires are arranged in the wall, but if there are some problems inside the wall, the wires will be damaged. For example, if there is a crack in the wall, there is some pulling force that will pull off the wire, which will cause the wire to be damaged and the socket to have no power.

Suddenly the lights don't come on, and the socket has power! But it's not hot when the socket is plugged into an electric blanket.

Suddenly the lights don't come on, and the socket has power! But the electric blanket plugged into the socket is not hot: there are two possibilities for the electric blanket light to be on or not:

1. The power switch time in the electric blanket is usually poor after a long time. The treatment method is to directly short-circuit the switch, communicate it with a thin copper wire wire, and then replace the switch with a socket. 2. If the heating wire of the electric blanket is broken, whether the electric blanket is broken can be checked with a medium wave radio, and if it is broken, then you have to buy a new one.

The socket has electricity, but the display light is not lit when this plug is plugged in, and the reasons are as follows:1There is a problem with the live wire and neutral wire of the socket, and the wire can be replaced2

The contact between the wire and the junction box has become loose3It is also possible that there is a problem with the lamp, such as the filament has been aged, or the lamp beads and light source driver, these accessories have failed, which will cause the lamp to not be pin and cover bright.
