Round trip switch line installation 40, back and forth switch line installation

What you are talking about is not the corridor switch, two switches control a lamp, which is to be used with two single-open and double-control switches, and the following wiring method: the zero line directly enters the lamp, and the live wire enters one of the public ends of the single-open and double-control switches (some of the targets are com, and some are l).A lot of it is the middle one, and then use two wires to connect the wiring holes on both sides of this switch (L1, L2).

The other end of the wire is connected to the wiring holes on both sides of another switch, and the middle and indirect wiring holes of the other switch are connected to a wire to the lamp.

Single-control connection method and principle of electric lamp.

The light single control switch, no matter which one it is, can be regarded as a single pole single throw switch.

In the circuit diagram, it is marked as follows.

All single-control switches, regardless of the form, have only two binding posts (dual-control and multi-control switches are not counted for single control). Some switch binding posts are marked with L (some brands are marked with COM) and L1.

When wiring, L is connected to the incoming wire, and L1 is connected to the outgoing wire (in fact, it's okay to connect it upside down). At this time, special attention should be paid to the fact that the incoming line must be a live line. Schematic.

Precautions for switch installation.

1. Region. The switch in each area is different, for example, the bathroom belongs to the wet area, the switch socket should be purchased with a switch and indicator light as much as possible, and a waterproof cover should be installed on the surface of the socket to avoid water vapor entering, resulting in a short circuit.

2. Habits. The position of the switch is determined according to the living habits of the family, for example, most people are used to using the right hand, and the door is turned to the right, so the switch is suitable for installation on the left side of the door. If it is at the head of the bed in the bedroom or a relatively large living room, it is recommended to install a double control switch for more convenience.

3. The spacing between the switches of the TV wall.

If the length of the TV wall exceeds more than one meter, it is best to increase the number of sockets. For walls smaller than meters, the socket can be arranged in the middle. Try to install 5-hole sockets, the sockets are close to the TV outlet sockets, and the spacing can be kept above meters.

4. The installation height of the air conditioner switch.

The best position of the split air conditioner switch is about a meter away from the ground, and the desktop air conditioner switch should be set at a distance from the ground meter next to the window, and the cabinet air conditioner should be about a meter away from the ground. If the range hood socket is more than a meter from the ground, the height of the refrigerator socket is generally set to about a meter from the ground.

The round-trip (double-control) switch connects the two contacts of the two single-pole double-throw switches respectively, that is, the contact 1 of the switch 1 is connected with the contact 1 of the switch 2, and the contact 2 of the switch 1 is connected with the contact 2 of the switch 2, and then the knives of the two switches are connected to the two ends of the lamp as the two ends of the whole switch.

In this way, when the knives of switch 1 and 2 are connected to their respective contacts 1 at the same time or to contact 2 at the same time, the circuit is turned on and the lights are on. If one of the knives of the two switches hits contact 1 and the other hits contact 2, the circuit is not working, and the light is off. Therefore, both switches can control the light.

L1 is the input and L2 is the normally closed output. l is the normally open output. L1 is the A input, L2 is the A normally closed output, and L is the A normally open output, so that two switch panels can control the lamp at the same time.

The multi-control switch mainly realizes the control and monitoring of all lighting circuits, electric equipment control and infrared electrical appliances in home, hotel, office and other application environments. The design concept of the system is scientific and novel, powerful and comprehensive, and the appearance is high-end and beautiful.

Summary. Hello dear.

The method of opening and closing is as follows.

Keep a certain space of the switch to ensure the distance back and forth of the stable switch.

You may be talking about the situation that you have a type 86 (it looks like a square) switch, and the switch panel you are talking about can be removed (not the whole panel, but the small panel that your hand touches when you press the switch) and you have a screwdriver to drop it with a slight warp. Then you can put on the screws.

How to install the back and forth switch.

Hello dear, I'm the creator Jiangnan man, I'm happy to answer the question for you, your question has been seen by Xiaohan, and is answering the whole ear for you, the estimated time is three minutes, please wait a while Oh kiss.

Hello, the method of the switch is as follows, keep a certain space of the switch, in order to ensure the distance between the stable switch back and forth, you may have the situation that you have the 86 type (it looks like a square) switch, the switch panel you said can be removed (not the whole Tong is removed, but the small panel that the hand touches when pressing the switch) There is a screwdriver to gently warp it off. Then you can put on the screws. Wear-resistant hope it can help you.

The method of wiring the loop switch is as follows:

Tools required: switches, lights, pens.

1. First determine the position of the loop switch and the position of the lamp, and install the two switches in the appropriate position, at the position of the lamp, confirm the positive and negative poles of the lamp with an electric pen, and connect the two wires to the positive and negative poles of the lamp. At the location of the first switch, connect the two wires in the chain power supply to the two binding posts of the first switch. At the location of the second switch, connect the two wires of the first switch, as well as the wires, to the two binding posts of the second switch.

2. Connect the other two wires to the two binding posts of the second switch and connect them to the two wires of the light. Once the above steps are completed, both switches will be able to control the same set of lights for multiple controls. Remember to ensure the safety of the circuit when wiring, and if you need to operate, you can find someone or expert guidance.

Precautions for wiring the switch at home:

1. When wiring the switch in the home, it is necessary to choose different switches according to the total power of its electricity consumption and different areas. If the place where the switch is installed is wet, then a waterproof switch should be used, and the dust in the room is very large, and sometimes there will be some corrosive materials. At this time, it is not possible to install a switch on this area, so that it will not corrode.

2. When wiring the switch at home, if it is a switch with a knife switch, then it is necessary to use the fuse that the knife switch matches with each other, and it cannot be replaced by a metal wire. Some aluminum, iron, etc., are also not available.

3. When wiring, check whether the rated voltage and rated current of the switch are consistent with the electricity consumption at home, so as to avoid the situation that the switch is overloaded. When we wire the switch socket, we should install the switch in a dry and non-stained place, so that there will be no moisture, and it can also avoid short circuit in the switch, which will cause fire. Be sure to separate the lines clearly before wiring to avoid wrong connections.

It can be switched on and off.

**If you don't understand, you can ask.

Are you talking about the dual control switch.

Below is the wiring diagram of the dual control switch:
