What happens if you use the neutral line to control the switch, and does the dual control switch hav

The switch is installed on the neutral line, and the circuit is controlled to work by turning the neutral line on or off, and there will be a situation:

For example, if a light is switched on the neutral line, the light will not turn on once the switch is disconnected.

However, the two wires connecting the light bulb, because they are still directly connected to the fire line, once a person stands on the ground and touches the lamp head, there will be a risk of electric shock, which is an unsafe connection method; If the switch is connected to the live wire, when the light is turned off, the connection between the lamp head and the live wire is cut off, and it is safe for people to reach it.

Extended Information: Precautions for the use of the neutral line:

1. The working zero line shall not be repeatedly grounded on the load side of the leakage protector, otherwise the leakage switch will not work normally.

2. The branch of the leakage protector can only be used as the working zero line of this circuit, and it is forbidden to connect with the working zero line of other circuits, and other lines or equipment cannot borrow the working zero line of the line or equipment after the leakage protector has been adopted.

Other lines or equipment cannot borrow the working neutral line of the line or equipment after the leakage protector has been adopted.

wire) encyclopedia - control switch.

Install the switch on the zero line, and use the zero line to control whether the circuit works or not, there will be a situation: for example, a lamp, the switch is installed on the zero line, when the switch is disconnected, the light is not on, but the two wires connecting the bulb, because it is still directly connected to the live line, once the person stands on the ground and touches the lamp head, there will be a risk of electric shock, which is an unsafe connection mode; If the switch is connected to the live wire, when the light is turned off, the connection between the lamp head and the live wire is cut off, and it is safe for people to reach it.

The switch controls the neutral line, which will cause the line to remain live when the switch is turned off.

If it is easy to have an electric shock accident during maintenance, it is very unsafe.

The switch is not a zero line, you are a single open double control switch, so there are three binding posts, if you just control the lamp alone, the live wire into L, L1 or L2 out of the line to connect to the lamp head to grind, the zero line directly connected to another point of the lamp head.

The panel switch is generally composed of a bottom box and a panel, and its main part is the panel part, and the bottom box mainly plays the role of fixing and supporting the panel. With the deepening of people's understanding of electricity, coupled with the gradual attention paid to electricity safety, most of the switches refer to single-control switches.

As the name suggests, a single control switch refers to a single or multiple electrical equipment controlled by a switch, and it has a one-to-one or one-to-many relationship with the electrical equipment.

Nowadays, our common switches are mainly household types of switches, usually in the form of concealed and surface-mounted forms, in terms of their specifications, there are 86 type, 118 type, 120 type, etc., in terms of the number of switch buttons in the same panel, it is divided into single open, two open, three open, four open, etc. Household switches are usually made of metal conductive strips and wiring contacts made of engineering plastics.

At the same time, for the sake of convenience and beauty, people will make various colors of the switch panel, and at the same time, the material on the surface of the panel will be reprocessed, and the aluminum-plastic and aluminum-plastic brushed surface, stainless steel brushed surface, copper surface and so on will be developed on the basis of engineering plastic substrates.

Because often for convenience, put concentrated in a certain place, control a large area of electrical equipment, so people will save space and workload for the sake of saving space, set up a plurality of buttons on a panel to control different electrical equipment respectively, so there are two open, three open, four open and other single control switch panels.

No, the dual-control switch is generally to control the live wire, so the zero line is directly to the lamp, and the general one is not at the position of the switch!

1. When the switch controls the open state of the zero line, the live wire returns to the zero line through the load, and the zero line live wire has electricity, and it will have the same brightness when measured with an electric pen.

2. When the switch is open, if the wire is aged, through the greasy and humid section, etc., the zero line will have induction electricity.

3. The line with a long installation time will inevitably have weak links such as aging, lack of moisture and damage to the tide and plum dismantling, and the zero line will have induction electricity, and the amount of electric pen will be bright, but there must be no spark bright.

The diodes connected in parallel on the relay play a protective role to prevent the transistor from being damaged by the high voltage generated by the self-induction when the relay is de-energized and released.

Because the switch is turned off, the zero line is induced, and the shed is suspended and electrified. This electricity is directly through the device and then flows out to the end of the broken zero line. If the switch is turned on, it will return to normal and will not be charged.

The zero line cannot enter the switch, and the consequences may be dangerous

If the circuit is single and the zero fire double line is cut off at the same time, the zero line must be not charged. If the power supply of the external branch line of the other key hand is suspected, it may be possible to bypass this switch and cut off the zero line, so that the zero line Pei Wei is suspended and electrified.

The switch controls the fire line of faith. There will be no electricity at the zero line. This is due to the fact that the fire line has been disconnected by the opening of the bucket tan. The live wire will not pass through the switch. Connect to the zero line. So. We must keep in mind this sentence. The air balance is called the live wire inlet switch.

Summary. Is it okay to open and control the zero line with double control: Hello dear can open the double control zero line directly into the light, because the zero line is not charged, the live wire is live, the switch only needs to control the live wire of the lamp, so that the lamp is in an on-off state, and there is no need to control the zero line and grounding wire of the lamp, therefore, a double control switch only needs to be connected to the live wire, and the zero line does not need to be connected to the switch, but can be directly connected to the two lamp heads.

Is it possible to open the double control zero line: Hello dear A double control zero line is possible to directly enter the lamp, because the zero line is not open to this thick live, the fire line is live, the switch only needs to control the live wire of the electric light, so that the electric light is in the state of Xizhen on-off, and does not need to control the zero line and grounding wire of the electric light, therefore, a double control switch only needs to be connected to the live wire, and the zero line does not need to access the switch, but can be directly connected to the two lamp heads.

How to half of the zero line in the switch box.

The socket installed in the home decoration wiring is not enough for later use, and can only be used through the patch board.

The wire has been worn, the light wire goes directly into the switch box, and there is only one live wire in the switch box, and there is one less zero line.

If it is the switch of the light, only the live wire is right, the zero line does not need to enter the switch, and the zero line Jianzhou is directly connected to the lamp. What you see is a live wire in the open and stop tease off the box, which is the live wire of the power supply into the switch, and then refers to the search from the switch outlet line to the lamp, and the neutral line (n line) of the power supply goes directly to the other end of the lamp. The electricity is sent to the lamp through the live wire, and the zero line forms a loop and the lamp is on.
