What to look forwhen choosing a switch
Buy breakers best in specialty stores where the range lets you choose the option that best suits you in terms of functionality and design.Also in the store you can find quality made branded switches, for example, one-button switches Legrand.
Buying a switch for general-purpose electrical voltage of 250 V and 10 A load, make sure it complies with GOST R 51324.1-99.Also on the product must be a sign of
Notice, for a voltage and current rated switch.For example, switches Ceramic contact, the silver will operate reliably at a current of up to 4 A. Be sure to look at the number of switching circuits and the number of poles (unipolar, bipolar or tripolar).Well, of course, pay attention to the design of the mechanism (the cord (ceiling) switch, push-button, rocker, toggle or rotary) and the construction of housing (for installation in electrical appliances or for installation on the electric wire, for open or concealed electrical wiring).
For example, one-button switch hidden wiring characterized by a structure which provides for the accession of cables after the switch itself will be fixed in the socket on the wall.Thus, you can keep the wires from undue bending.
One Key Switch open installation is mounted on a wooden podrazetnikah, to which are attached with two screws.
If you plan to install the switch in a place where there is water ingress rice inside, look for one-button switches, splash-proof.
When you select the most suitable for you on the characteristics of the model, be sure to check the softness of operation keys.It is enough only a few times "turn off" button, and all should work quite smoothly - nothing should squeak or cling.Finally pay attention to build quality.
Install flow switch makes sense in places where conventional control switching on and off lighting uncomfortable and not practical.In particular, we are talking about long corridors, stairwells, etc.Typically, such areas are set special one-button switches equipped with three contacts, a particular connection scheme which is implemented as switches.During operation of such a device switches the electrical circuit between the two output terminals, and is not broken.
Choosing entrance switch, pay attention to the modification of the device, which may vary depending on a device which is designed wiring - hidden or open.So when buying a switch, consider all the characteristics of the device, since contacts are rated for a different current and thus can withstand different loads.
What is different from the normal flow switch
The main difference from the usual flow switch is the presence of a special mechanism for switching between three contacts, which are provided in such switches.Work flow switch is not based on a conventional circuit termination and to be able to switch between tracks.
Wiring flow switch:
Wiring flow switch:
Hence, the main advantage of walk-through switches, which is the ability to on-off lighting unit of two or more points.
As already stated above, the bushing makes sense to install switches in long corridors and stairwells, for example, on the first and second floor.That is on the first floor we can include lighting the stairs and climbed to the second floor, turn it off.
also communicating switches can be installed in the bedroom - one at the front door and one by the bed - or on private land where there is a need lighting tracks at night.

Installing one-button switch
If you need to replace the old, the failed switch, this kind of work takes you a little time and complexity, as such, in the course of their implementation is notarise.However, when it comes to settling into a new house or apartment circuit, then the work of the forthcoming more complicated.Just below we will tell you how to install your own hidden switches and overheads.
mounting junction box for one group of lighting
required before work on the installation of the switch, make sure that the electricity is turned off.
When it comes to creating a new circuit, and thus the need to conduct new wiring, you must immediately decide for yourself what it will be - open or closed.Of course, with open wiring, which is laid on the surface of the structure (or open, or in a box) and the problems will be less.For such a bill, or the wiring is suitable, as they are called, the switch open installation.
If you do not want to wiring was hidden, then there can not do without a bulky work, in particular shtrobleniya walls.
Thus, in contrast to the kind of wiring decided to hold the switch can be either outdoor or flush mounting.In the latter case, the switch is mounted in a box built into the wall.In the first - simply placed on the wall surface.
If you run a new chain planning and installation of the junction box for one group with one-button light switch and lamp on one group of bulbs, then it must be held six wires.Two wires to the lamp, two - the switch and two feeding.Driving such a chain will have the following form:
When all wires wound in a junction box define them using an ohmmeter, wire feeding phase voltage indicator and warning lamp.Defining wire neutral conductor (N) must be connected to the wire lamp connected to the side contact elekproptarona and phase conductor (L) - to connect to the wire going to the switch.The remaining two wires are interconnected.
Installation hidden switch
If you just want to change the switch, then all of the above works, of course, is not necessary.Or, when you have determined where it will be conducted and the switch to this place wires, you can install the switch itself.
Installation One Key switch flush mount involves the installation of metal or plastic mounting box, as they can be hollow or solid walls.
a standard size box is 4 cm and depth of 7 cm diameter.As for the material, it is better to give preference to heat-resistant plastic, as it is much safer metal.
Before installation of the mounting box unscrew the screws and break down the plug hole to its constituent wires.To securely hold the box in a wall niche, it is recommended to take advantage of alabaster.Boxes for hollow walls, for example, gypsum board attached with staples.
Connection diagrams one-button switch:
Attach the wires to the switch four ways, while not all of them are considered safe:
- wire clamped section of the screw.This type of connection is the most dangerous, since in this case the wire can be severed just still tightening.
- Keyless method involves the installation of a wire into the hole at the position of the pressed key.Then, when the key is released, it is clamped.Worse, this method in that during the operation of the switch spring gradually lose their physical properties, and therefore gripping force decreases and the contact can start to heat up.
- wire is pressed against the contact platinum cap screws.
- latter method is the most reliable and he is pressed against the wire plate which moves with the screw and wire clamps.
So, to understand the methods of connecting wires, you can proceed directly to the installation switch.To do this, use a screwdriver to carefully remove the key and the lock, through which held the top pad.After removing the trim switch is disassembled quickly and easily.
Clutching wires in the sockets, the switch is fixed to the box with screws or special levers.
switch Installation Surface
process of installation Surface-breaker runs similarly hidden, with the only difference - there is no need to install and Stroebe wall mounting box.The only downside of the outer one-button switch is size.
In general, the whole process of installation of the switch is reduced to the layout of the future mounting holes, drill them, setting anchors and, in fact, connecting wires and mounting the switch on the wall.
That's the whole process of assembling simple one-button switch.As you can see, if it is just to replace the old switch to the new, the installation process is so simple that it can be done, and himself, without causing an electrician.If we are talking about creating a new circuit and the installation of a new junction box is here, of course, for security is best to seek professional help.
