How to wire the duplex switch, how to wire the duplex switch

First of all, we need to prepare two duplex switches, this kind of switch is different from the general switch in that it has 3 binding posts, and the general main binding post is named L. The secondary binding posts are named L1L2 or two L2 (refer to the product manual for details), and the main binding post means that one of the two secondary binding posts can be connected arbitrarily.

Let's start by looking at the circuit diagram. It is believed that it is relatively easy to understand, the secondary binding posts of the two switches are directly connected with wires, while the main binding posts are connected to the live wire of the circuit and the neutral wire connected by the bulb.

Let me tell you that the main point of this wiring method is that the bulb should be connected to the neutral line. In this way, as long as the light is off, the line on the bulb is not charged, and it is safer to change the bulb. And if you do the opposite, it will not be safe.

In this way, if the light does not turn on when you press the switch at home, do not press the switch back and forth many times, but reset the switch and then replace the bulb. Of course, you must also pay attention to ensure that you do not come into direct contact with the earth to prevent electric shock.

There is also a wiring method opposite to the above wiring method, the position of this wiring method is the secondary wiring live wire and the neutral wire, and the main binding post is connected to the bulb and another main binding post. Although this method saves wires, this method is not recommended, because there is no guarantee that the bulb is not charged when the light is off, so you must make sure that you are not conductive with the earth when you change the bulb.

The following is the layout of the switches. If the switch is for the bedroom, one is for the doorway and one for the head of the bed. In the stairwell, it is an upstairs or downstairs for easy switching.

Finally, if you need to control 3 positions, it can be realized. An additional switch with two duplex switches together is required, and their two main binding posts are connected to the secondary binding posts of the first switch. Their secondary binding posts are connected in two ways so that the two binding posts are connected to the secondary binding posts of the next duplex switch.

The switch in the middle of these switches can act as a third switch.

For stairs or bedside, 2 dual switches can control the turn of a light on and off at the same time? The method is simple. Unify the L1 of the two switches (L1 of switch 1 and switch 2 is connected to the live wire) and L2 (the L2 of switch 1 and switch 2 is connected to the neutral wire).

Respectively connected to the neutral line of live (that is, the 2 switches are connected to the power supply in parallel), note that this can not be connected wrong (otherwise it will be short-circuited), in the L pole of the 2 switches respectively, a wire can be connected to the two poles of the lamp.

The methods of duplex switch wiring are: alternative method, provincial line method, and traditional method.

1. Alternative method: connect one end of the two switches to the live wire, and the other end is connected to the electrical equipment, so that the two switches control the live wire.

2. Wire saving method: connect the electrical equipment to the middle of the two switches, so that the switch controls the live wire and the neutral line at the same time as the circuit.

3. Traditional method: This kind of wiring is more common, one end of the circuit is connected to the live wire, and the other is terminated to the zero wire.

Precautions for switch installation

1. Region: Due to the different uses of each area, the natural use of the switch should also be different, for example, the kitchen and bathroom belong to the wet area, when choosing the switch, try to make the kind with the switch and the indicator light, it is best to install a waterproof cover outside the switch, so as to avoid the entry of water vapor and prevent the phenomenon of short circuit.

2, the bright infiltration habits: for the location of the switch, must be determined according to the living habits of the people at home, for example, most of them are accustomed to using the right hand, the door will open to the left, then the switch is suitable for the left side in front of the door, in addition to the bedroom or some larger living rooms, it is recommended to install a double control switch, increase the convenience of use.

3. The spacing of the TV wall switch: If the wall height of the TV wall is above, it is recommended to increase the number of sockets, if the wall is lower, it is recommended to install it in the middle position, and when choosing the socket, try to install a 5-hole socket, the socket should be located near the outlet of the wire, and the interval should be kept above and above.

Summary. Hello, dear, take two dual-control switches and a light separately for a specific introduction. Dual-control switch binding posts are generally marked"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. 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 illuminator, and the other end of the illuminator is connected to the zero wire.

How the duplex switch is wired.

Hello, dear, I have seen your question and am organizing the answer, please wait.

Hello, dear, take two dual-control switches and a light separately for a specific introduction. Dual-control switch binding posts are generally marked"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.

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 illuminator, and the other end of the illuminator is connected to the zero wire.

Concatenation. If it is a single-link dual-control switch, then when connecting the wire, Chakong should first connect the incoming and outgoing wires of the live wire to the binding post marked with L respectively, and then connect the binding post L1 on the single-connection and double-control switch with the binding post L1 on another single-connection and double-control switch, and then connect the binding post L2 on the single-connection and double-control switch with the binding post L2 on another single-connection and double-control switch. If it is a double-link single-defeat slow blind control switch, then the wire connection method is the same as that of the single-open single-control switch.

Switches L1 and L2 are connected to the Slippery Lighting Line, if a switch controls a lamp, select a connector in L1 and L2, the difference is only that the front button is not in the same direction.

Switches are something very common in our daily lives. However, there are many kinds of switches, the total is divided into single control switches and double control switches, and the double control switches are divided into single control and double control. We may know more about the single switch, today I will introduce to you what is a double switch, let's take a look!

1. Introduction to duplex switches.

Duplex switches are divided into duplex single control switches and duplex dual control switches.

A single button is a single button, which is single-controlled: that is, it has only one contact (normally open or normally closed). Dual Control:

That is, it has two contacts (NO and NC). These switches are ridged to refer to the buttons, the kind with springs. The single-link single-control switch is generally used for jog control, and the double-link single-control switch is generally used for long-acting control.

Second, the working principle of the duplex switch.

"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, can be opened below and closed at the top.

"Single-link and dual-control" refers to two buttons with a certain distance to control a group of light sources at the same time. "Single-link, single-control" refers to the control of a set of light sources by a button. 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".

1. Difference: Two-open single control refers to the switch that can only control one circuit for both. Two-open and dual-control refers to two switches that can control two circuits, and are usually used in the staircase light control and bedroom light control at home.

That is to say, the two open single control is the two open and collapse closed to control the two lights. And the two-open dual-control is to control two duplex lights.

Second, the switch is open: it means that a panel has two covers, that is, there are two switches, and the two switches are close together.

Third, the single control of the switch refers to the ordinary switch, as if, there is a wire on the left, there is a wire on the right, the line on the left can only be connected with the wire on the right, and it is connected to the air when it is not connected.

Fourth, the switch dual control is like, there is a line on the left, there are two wires on the right line and offline, when the left line is connected to the right line, the line is equipped with a thick circle and electricity, and when the line is disconnected, it will be connected to the line, and the line will be electrified.
