Do the math how much it will cost you to renovate your home

Modern home life is inseparable from electricity, switches and sockets as electrical accessories often used in our daily life, especially duplex switches are commonly used in the stairs and aisles in the home, so what is a duplex switch, how to connect the duplex switch, and what does the wiring diagram of the duplex switch look like when there is a failure? It doesn't matter if I don't know, I'll introduce you here! The double switch is divided into two kinds of double single control and double double control, the single switch refers to the combination of two single open, control the lights of two points, and the double control switch is mostly used for the control of two positions to a point light switch.

What is the wiring diagram of the duplex switch? Through the connection of different terminals to achieve different effects, there are live wires and neutral wires in the wiring diagram, and the functions and connections of each terminal must be distinguished when wiring. How to connect the duplex switch?

Generally, there are two methods, one is the traditional safety connection method, one of the double wires must be directly connected to the middle and indirect wire ends of the two double switches, and both switches are connected to the live wire; The other is the wire saving method, although it can save the wire, but the safety hazard is very large, and it is easy to cause a short circuit. "Duplex single control" means: there are two single-control buttons on a panel, and both buttons are one-way control of the switch of the lamp, that is:

The light can only be turned on and off in a fixed place, unlike the two-way control switch used in stairwells, which can be turned on and off at the bottom. The double-link single-control switch is generally used when there are two sets of light sources in a room. The above is the relevant knowledge of the duplex switch, mainly the understanding of the duplex switch, understand what is the duplex single control switch, and learn how to connect the duplex switch.

I hope it will be helpful to you, so that you can better understand the relevant knowledge and enrich your knowledge base. If you are satisfied, please give a thumbs up.

"Duplex single control" means: there are two single-control buttons on a panel, and these two buttons are one-way control of the switch of the lamp, that is: can only control the opening and extinguishing of the lamp in a fixed place, different from the two-way control switch used in the stairwell, which can be turned on below and closed at the top.

It is generally used when there are two sets of light sources in a room.

Single-linked, single-control. Refers to the control of a set of light sources with a single button.

Single-link and dual-control. It means that there are two buttons with a certain distance to control a group of light sources at the same time. For example, there are controls for corridor lights on both sides of stairs.

"Link" refers to several switch buttons on the same switch panel.

"Control" refers to the control mode of the switch button, which is generally divided into: "single control" and "double control".

The wiring method of the duplex single control switch is as follows:

1. First of all, distinguish between the neutral wire and the live wire, under normal circumstances, the live wire is red, the neutral wire is directly connected to the bulb, and the live wire is connected to a switch.

2. Then use two t wires to connect the two switches in series, and connect the live wire to the bulb with another switch.

3. Need to find the binding post L1 and L2 of the switch first, need to connect the wire on these two binding posts after finding, then need to connect the live wire to one end of the terminal post L, and at the same time the other end of the lamp needs to be connected to the other end of the terminal post L, and the other end of the lamp is connected to the zero line.

4. You need to close the electric valve at home before wiring.

The above is the wiring method of the duplex single control switch, the lamp plays a very important role in our daily life, so we must have a general understanding of the lamp and switch, so that we can use them better.

1. The panel is different.

Single: It is a switch, the panel has a pedal, which is divided into single and single control, single and double control.

Duplex: It means that two switches are side by side, and there are two pedals on a panel, which are divided into double single control and double double control.

2. The binding posts are different.

The single control switch has only two binding posts, one in and one out, to control the closure of the line; The dual control switch has three binding posts, (it can be one in and two out, or two in and one out, of course, it is also used as one in and one out.)

3. Different usage.

A single-control switch is a switch that controls a light; The dual control switch is to control the opening and closing of the same lamp with two different places, such as the living room, stairs and other positions, so that it is not necessary to go back to the bedroom in the dark after turning off the light (entrance door), which is very convenient.

The difference between single opening and double control and double opening and double control is that there is one more lamp head line and two double control lines.

If it is connected to double open and double control, a total of two switches are required.

A set of power cords is required, one fire and one zero.

Two sets of dual control lines are required, with a total of 4 wires.

The two lamps require a total of two lamp head wires.

The dual dual control is two switches, which can control two lights separately. The air switch has single pole, 2 pole, 3 pole, 4 pole. Single pole controls live wire, 2 poles control live wire and neutral line, 3 pole controls three phases, 4 poles control three phases plus neutral wire.

Pole: The number of wires on the port on the introduced switch. This is the number of wires that can be turned on or off at the same time.

Coupling: Several of the same switch on the same panel is called several coupling. Control:

The number of contacts that can be switched on (or off) in different positions after the switch is actuated. The short term is a few knives and a few cuts (also called throwing; Control:Such as single-knife double cut; double knife double cut; The transfer switch of the pointer multimeter is multi-knife multi-cut.

Simultaneous transformation of multiple circuits on and off).The voltage phase-change switch is also multi-knife and multi-cut.

A double-link dual-control switch is a panel with two dual-control switches.

The double switch is a switch panel with two sets of switches, which can control the two lights to be turned on and off respectively, and the double control switch is a switch that can realize the switch lights in different places, and it has three terminal points, one is the common end, and the other two terminals are on or off respectively.

Summary: What does a single-gang dual-control switch mean? Single-call filial piety double control switch refers to the simultaneous control of a lamp in two different places, such as a switch at the entrance door of the bedroom and at the head of the bed, and these two switches control the bedroom light at the same time.

If the home and the letter choose a single-open and double-control switch, and the correct wiring method should be taken, how to wire the single-open and double-control switch? Let's find out. 1. What does a single-connection and dual-control switch mean?

A single-pole double-control switch is actually a switch that connects two single-pole double-throw switches in series and then connects to the circuit. Each SPDT switch has three terminals, one with two contacts and one knife. At the three wiring points of the single-connection and dual-control switch, one is the inlet end of the live wire, and the other two are the outgoing end of the live wire, that is, two live wires are set between the two switches.

Single-connection and dual-control switches are widely used in daily life, one switch controls multiple or even multiple groups of electrical appliances, and is often used in stairwells in schools, hotels, and families.

Second, how to connect the single-open and double-control switch to the Tan Yu line.

1. If you want to open a single dual-control switch, the wiring method is relatively simple, first of all, we need to distinguish the live wire and the neutral line, which can be directly distinguished with an electric pen. After the distinction is made, connect the live wire to the L binding post of the first switch, and then connect the other two live wires to the L1 and L2 binding posts of the first switch respectively.

2. At the same time, it also needs to be connected with the L1 and L2 terminals of the second switch, and then the control line of the lamp is connected to the L terminal of the second switch, and the zero line should be connected with the corresponding binding post. Finally, pull the wire to see if there is a loose problem, if not, and then tighten the wire with screws. Turn on the power, see if it's powered on, and if it is, cover the panel again.

In today's home life, we inevitably need to use switches, which facilitate our electricity life and can be said to play a very important role. Now there is a single and double control switch, some friends don't know what it means, the following is a brief introduction for you, I hope it can help somewhat.

1. What does a single-link and dual-control switch mean?

As the name suggests, this type of switch controls the circuit through two single-pole double-throw switches. The two SPDT switches have three interfaces for connecting wires, connecting them with a knife and two contacts, and then connecting them in series, so that Changji can control the circuit.

Second, the installation and use of switches should pay attention to the vertical file.

1. First of all, before installation, we should go to the market to buy the right switch, the quality of the switch must be good, can not buy the kind of three no products, so there is no safety guarantee, there will be a lot of problems when using, and there are even potential safety hazards. So we have to go to a reputable merchant to buy at the beginning, and if there is a problem with the switch, we will also give after-sales service.

2. When installing the switch, make sure that there is no problem with the line connected to the switch, if there is a wiring error in the line, then the switch will not be able to use normally. When installing, we must first turn off the power supply at home, and we must also wear insulating gloves to prevent leakage and electric shock, which is very dangerous.

3. If you don't have any experience in installing switches, it's best not to try it yourself, because this is a technically difficult job, and it's better to ask professional personnel to help install it.

4. When using the switch, if there is water on your hands, it is best not to touch the switch, which is easy to be electrocuted. If you find that the shell of the switch is falling off, don't leave it alone, and install the shell or replace the switch in time.

Summary: The above is for you to introduce the content of what the single and double control switch means, I hope it can be helpful to you, if you are not very clear about this aspect, you can refer to the above content to understand.
