Getting into a room that does not have a highlight level, we immediately turn on the light. To implement this manipulation there is a special device - a switch. It would seem that it could be easier? But with a thorough study of this issue it turns out that it too has its secrets.
This article provides detailed information about theswitches of various types, their field of application is indicated. Also you have an opportunity to get acquainted with the scheme of their connection. Having thoroughly studied all the material below, you can easily install a switch of any type at home, the main thing - observe all the precautions.
Switches (switches) are different:depending on the functionality, design, installation method, etc. This device must be made of high-impact material (usually plastic) of high quality, having a smooth surface. Install switches in places that will be easily accessible. This device functions in hidden, as well as open wiring.
As for the design of the switches, itdiffers in variety. There are devices of the classical type. There are models that give the interior of a certain room originality, a highlight. The color spectrum of the switches can satisfy the most demanding customer, so there should not be any problems with the combination of furniture, wallpapers and other interior items and a switch. Some companies also manufacture switches with decorative replaceable panels. After the device has been mounted, it is possible to install various overlays on it.
Switches can be ordinary and through;single, double and triple. In this article, we will talk about loop-through switches designed to be able to include one light group of two or more places. The following important topic will also be considered: "Feed-through switch - connection diagram of this device".
In conventional switches there is an interruptioncircuit current. In contrast, transient models have three contacts with the device, which provides a switching process between them. A double-pass switch has such contacts six.
The main advantage of the transition switch is that you have the ability to switch the lighting on and off from several places.
Pass-through switches are also called changeover, or duplicating switches.
There are four main areas in which pass-through switches are used.
The scheme of the passage deviceIt reminds me of switching of arrows of railway tracks, since it can be activated at any position of the keys, because they switch from one line to another.
So, the pass switch:The connection scheme of this device is explained as follows. Two pass-through switches, one of which receives the phase, and moves from the second to the luminaire, must be combined with a special wire or cable. But, as a rule, they are not directly connected, instead of placing three wires in the junction box from each one, and connecting two of them to each other.
Circuit switch circuit to whichin addition, if necessary, a certain number of cables can be connected, in essence, does not change. The only difference is that the first two cables have only one input contact, and the output - two. And if you increase the number of cables, then, accordingly, you will have to increase the number of input and output contacts: two for each. This will ensure their use between the two lines in a crossover way.
As for the third passswitch, then you first need to make sure that he has the ability to perform the functions of the cross - this should be checked at the very purchase. The scheme of operation of such a switch can be described as follows: switching occurs, a third switch at the input connects the first contact with the second one at the output, and vice versa, the second contact at the input with the first at the output. To make the connection of this pass-through device, you can simply connect it with a two-core cable to two other pass-through switches. But most often, instead of this, they take a four-core cable, lead it to a junction box, and there already make a switch.
By the same principle, a fourth one can be added to the wiring diagram of the walk-through switch. Then it will be placed between the first / second and third switches.
So, pass-through switch, wiring diagramThis device, the principles of its functioning - this question was considered. Now let us dwell on one of the types of transition switch - double, which can still be called two-key.
Usually, two-key switches are placed inareas where there will be separate inclusion, directed from different places of the two lines of illumination. In the corridors, as well as in the area of the stairs, a single walk-through device will be quite enough.
In the double switch on the keys should be arrows: they serve as an indication of the direction of the key to turn off or turn on the lights.
The structure of the double-gangway switch includes two single-key devices. They are combined in a single case and work by throwing contacts.
Device of the two-gang switchimplies two independent groups of contacts. When you press the keys, they switch from the upper lines, which are not interconnected in any way, to the lower ones, which, in turn, follow to the second same switch.
So, we have two groups of contacts:right (contacts No. 1 and 2) and left (contacts No. 1 and 2). Then the scheme of the two-button pass switch can be explained as follows. Phase from the junction box of your home comes to contact number 2 of the right switch. Further, the contacts of the same group are connected by a jumper, and from the left group they are moved to two independent lamps. It should be noted that these two contacts should not intersect each other. Now these four cross contacts must pair up.
So, the two-button pass switch - the scheme of such a device is quite clear. The task becomes a bit more complicated if you decide to implement a cross connect.
To connect a cross feedThe switch will need to be combined with four wires with each end. Usually, eight wires from the cross and six from each pass-through switch to one junction box are wound up for this. At the same time, we must not forget that it is necessary to place a power supply cable there - this is necessary in order to connect chandeliers or small lamps.
Осуществляя такое подключение двухклавишных pass-through switches, you need to carefully monitor all your actions so as not to confuse the pair and not connect wires from different lines to the same switch. So the scheme will not work. It is advised to imagine in mind that two independent one-button pass switches are connected, which are interconnected in one housing.
Legrand is a company that occupies one ofleading position in the global market of electrical accessories. Switches are obligatory components of each product line of this French company. Legrand is famous for the variety of its devices, which have different shapes and colors. It should also be noted that it is not necessary to doubt the reliability and quality of the switches of this company.
In order to give a rough idea of what the pass model is all about, let us give a characteristic of such a device as the Legrand Valena single-key one-button switch:
Whatever the switch - one-key ortwo-key, white or black, by Legrand or not, but working with it is a manipulation, first of all, with electricity, but it is known to be very dangerous. Therefore, we should not forget about the elementary safety rule: it is necessary to turn off the power supply in the room in which the installation process will take place. And it is better to completely de-energize the whole house - it will be more reliable.
