There are several ways to connect the dual control switch How to connect the double control switch

1. There are generally words such as L, L1, L2 and other words in the switch panel that you buy, 2. Use a tool to keep the plastic skin of the thread head, don't leave too much, and avoid the line and the line from touching together.

3. First of all, connect the line at the end of L with the end of L1L2.

4. After the switch is turned on, connect L1L2 and L at the other end.

5. Take the L of the left switch as the live wire, connect the L1L2, and then connect the L point on the right to one side of the lamp, and connect the other side to the zero line.

6. The last step is to connect the original left live wire with the neutral wire, and this is done.

What is a dual-control switch and how should the dual-control switch be wired? This is very difficult for people who have never learned the circuit at all, and they don't even know what a dual-control switch is. When I was a child, I thought it was amazing to turn on the switch when I was downstairs and turn off the switch when I got upstairs, but when I grew up, I realized that this was actually a dual-control switch.

A dual-control switch is a switch with two contacts (i.e., a pair) of normally open and normally closed at the same time. How to wire the dual control switch? Let me tell everyone!

There are several ways to connect the dual-control switch

If you want to turn off the lights, you have to run downstairs to turn them off, and you can avoid this trouble by using dual-control switches. There are several ways to connect the dual-control switchAs follows:

There are 4 types of connections, which are:

1》L is connected to the phase wire, L1 is connected to the control line.

2》L is connected to the phase wire, L2 is connected to the control line.

3》L1 is connected to the phase line, L is connected to the control line.

4》L2 is connected to the phase wire, L is connected to the control line.

1. One of the double lines must be directly connected to the middle and indirect terminals of the two double control switches;

2. Another wire in the double wire is connected with the upper terminal (or lower terminal) of the two switches, and a branch wire is connected with one end of the lamp in the middle of the indirect, and the other end of the lamp is connected to the zero wire;

3. Both switches are connected to the live wire, and are connected to the upper terminal (or the lower terminal), but not to the middle terminal.

Wiring characteristics of dual-control switch circuit:

1. A wire in the double special line, and the branch wire in the middle is connected to one end of the lamp. (The traditional duplex dual-control circuit is not allowed to lead out of the branch line in the duplex dedicated line).

2. Both switches are into the live wire, and can only be connected to the upper terminal (or lower terminal), which makes the light on, the measurement voltage of the three terminals of the two switches to the neutral line is 220V, that is, the test pen is displayed in red.

Precautions for purchasing dual control switches

1. First of all, we should be optimistic about the appearance, and see that the style of the switch should match the overall style of the interior. Take a look at the surface of the product, which is smooth and smooth, uniform in color, and textured, and the surface can not have any burrs.

2. Materials, good switches are mostly made of bulletproof glue and other materials, smooth surface, flame retardant, insulation, impact resistance and moisture resistance, etc., in addition to the use of advanced plastics, the current switch panel also has gold plating, stainless steel, copper and other metal materials, providing people with more and more choices.

3. Feel the feel, be sure to touch how it feels, whether it is smooth, the elasticity of a good switch is excellent, the turning point of opening and closing is relatively strong, no bubbles, no scratches, no stains. Good switches generally use metals such as copper, and they will not be light.

Summary

After reading this article, I immediately feel that the connection of the dual control switch is very simple! But when you are not sure whether the connection is correct, you must have an electric pen or ammeter to test the following, and when wiring, you need to turn off the power and reconnect it. Electricity safety, pay attention to yourself.

In modern decoration, the transformation of the circuit is an important project, and the electricity at home is not limited to lighting electricity, and comfort and convenience have become the "standard". The dual-control switch has become a sweet spot in everyone's eyes, the wiring of the dual-control switch is not a simple matter, how many ways are there to connect the dual-control switch? Let's take a look.

In modern decoration, the transformation of the circuit is an important project, and the electricity at home is not limited to lighting electricity, and comfort and convenience have become the "standard". The dual-control switch has become a sweet spot in everyone's eyes, the wiring of the dual-control switch is not a simple matter, how many ways are there to connect the dual-control switch? Let's take a look.

Wiring method of single-link and double-control switch

Single-pole double-control switch is simply two single-pole double-throw switches connected in series and then connected to the circuit again. Each SPDT switch has three terminals connecting two contacts and one knife. After knowing this information, it is not difficult to know how to wire the single-gang and dual-control switches.

Connect the two contacts of two SPDT switches, and then the knives of the two switches are connected to the two ends of the lamp as the two ends of the entire switch. In this way, when the knives of switch 1 and 2 are connected to their respective contact 1 or contact 2 at the same time, the circuit is turned on, and the light is on, so that both switches can control the light. Two switches can be placed at the bedroom doorway and at the head of the bed, or at both ends of the hallway, which can not only illuminate, but also save time and effort.

Wiring method of double-link and double-control switch

The double-link dual-control switch is a two-button switch, simply put, it means that on a panel, two buttons are used to control two light sources, that is, two switches control these two circuits. First, connect the middle line post of a double control switch to the live wire, then connect the middle line post of another double control switch to the lamp head, and then connect the back and forth wires, that is, use two green wires to arbitrarily connect the upper and lower two binding posts; The neutral wire is connected directly to the other contact of the lamp head, and the connection is complete.

Triple double control switch wiring method

The principle of the triple dual control switch is the same as the above two kinds of dual control switches, simply put, two switches to control three circuits. For the wiring of the triple dual control switch, put one inlet wire first, release six wires, each two as a group, put it to other switches, each group of wires is discharged to the switch and then put one to the lamp, and the zero line is directly placed at the lamp.

Switches are a very small part of home improvement, but their role is irreplaceable. The installation of these concealed projects plays a vital role in the whole home life, when you want to turn off the lights in the living room, but not in the living room, always run to the living room to turn off the lights is a troublesome thing, so the double control switch is designed for this function, you can no longer run to the living room to turn off the lights, as long as you want to turn off the lights in the place to install such a switch, you can enjoy the convenience and speed of modern life.

The above are the three connections of the dual control switch that I have introduced to you, which are practical in daily life, and will definitely help you when installing the dual control switch in the future. If you're troublesome, it's also a good idea to find an electrician to help.

Dual-control switch, I don't know how you understand it. Next, I will first explain to you what is a dual-control sail switch? The dual-control switch is a switch that can be turned on or off at the same time for two electric shocks, and the electric shock can understand our common lights.

We usually use two dual switches to control the same light or electrical device on or off. For example, we can turn on the lights in the corridor downstairs, and when we get upstairs, we can turn off the lights in the corridor upstairs, which saves a lot of trouble? So how exactly is the dual control switch wired?

See below for details.

1.Alternative wiring method for dual-control switching circuits.

The dual-control switch circuit is alternatively connected to the Zen jujube line method, which means that both switches are in the live line, which is very safe. It can be seen on the diagram, but it is rarely used in reality, and few people wiring it like this.

Alternative wiring to the point:

a. One of the lines in the dual-control switch line must be connected to the middle and indirect wire ends of the dual-control switch.

B. In the double control line, a wire is required to be connected to the upper terminal of the two switches, and a wire is connected to one end of the lamp in the middle, but the other end of the lamp must be connected to the zero line.

c. Because both switches are required to be connected to the live wire (connected to the upper terminal), it is also required that they cannot be connected to the intermediate terminal.

From the figure, we can see the wiring characteristics of this wiring method circuit:

a. There is a wire in the special line for dual control, and a branch line is divided in the middle to connect to one end of the lamp.

b. The two switches are connected to the live wire together, and can only be connected to the upper wiring and the dismantling end. This makes it possible to measure the voltage of the three terminals of the two switches under the zero line at 220V when the light is on, and the voltage test pen will be displayed in red.

2.Traditional wiring methods.

This traditional wiring method is mentioned in physics books for junior high school and high school, and it also appears in general standard engineering drawings, which is relatively common.

3.Alternative provincial line method.

Theoretically, there are certain safety problems in this wiring method, but it is still very commonly used in the dual control wiring of the family, saving money and manpower. Because copper wires are much more expensive than before, this wiring method is the most convenient and cost-effective for plumbers.

Wiring points: a. Pull a wire on the middle and indirect line posts of the two dual-control switches and connect them to the lights you want to control.

b. For the other two terminals of the switch, one section is connected to the live wire, and one section is connected to the zero wire, so that it can be connected, the idea is very simple, and the switch with good quality will not easily occur short circuit.

1. Tools Raw materials: screwdrivers, diagonal pliers, double control switches, lights, wires, insulating tapes.

2. Take two dual-control switches and a lighting lamp separately to introduce them in detail.

3. The binding posts of the double control switch are generally marked with L, L1, L2. When the L end enters the line, L1 and L2 have one end and L on, and after pressing the switch, the other end of L1 and L2 is connected to L.

4. Peel the thread with diagonal pliers first, and be careful not to leave too long the thread to avoid touching.

5. Take the L of the left switch as the live wire input, the L1 and L2 of the two switches correspond to the wiring, and then connect the right switch L to one end of the lamp, and the other end of the lamp is connected to the zero line.

6. After connecting the wire, pay attention to wrap the wires on both sides of the lighting lamp with insulating tape to prevent leakage.

7. The plug of the last live wire and the neutral wire completes the wiring of the entire double control switch.

8. In order to facilitate wiring, you can remember the circuit diagram of the double control switch, so that it is easy to wire in actual operation.
