Wiring -through switch

-through switches allow you to control light from two or more different places.In some situations, this is not just an added convenience but a necessity.

You are invited to get acquainted with the peculiarities of the walk-through switches, the main options for connecting them directly and installation instructions.

Why communicating switches?

Most of these switches are used in the following places:

• staircases.You can set the switch on the 1st and 2nd floors.At the bottom turn on the light, up the stairs, turn off at the top.For buildings higher than two stories in the scheme, you can add additional switches;
• in the bedrooms.Set the switch at the entrance to the room, and one or two beside the bed.They went into the bedroom, turned on the light, got ready for bed, and went to turn off the lighting device mounted near the bed;
• corridors.Set the switch at the beginning and end of the corridor.Go, turn on the light, we reach the end, turn it off.

list is very long, because almost every situation has its own version of the application of the system-through switches.

designs System switches

There are several connectivity options considered devices.We are offering the most popular and successful of them.

scheme for the control of lighting from two locations

The system is assembled from two through-type single switch.

Each of these devices has one contact location in the input and output contact pair.

from the power source through the distribution box is connected to the lighting device wire "zero."phase cable, also passing through the box is connected to the common contact of the first switch.The output contacts of the switch by means of the box are connected to the output terminals of the next device.

At the end of the wire of the total exposure of the 2nd switch through the junction box is connected to the lighting device.

Manage multiple lighting groups of two places

There is an option that allows you to manage two places different groups of lighting fixtures.For example, we need to organize the possibility of lighting control in a room directly from most rooms and from the adjacent corridor.Available chandelier 5 lights.We can set the system-through switches on and off two groups of lights in our chandelier.

The diagram illustrates an embodiment of the separation of light bulbs into 2 groups.In one of their 3, in the second - 2 Number of lighting fixtures Group may vary at the discretion of the owner.

For arrangement of such a system are also using 2-through switch, but they must be double type, rather than single, as in the previous version.

design double switch has 2 contacts in place inputs and 4 output.The rest of the procedure remains the same connection the previous method, changing only the number of cables and controlled lighting.

control lighting of three places

the previous version, this connection method is different only in that part of the circuit switch is added to the cross.This device 2 in the contact place input and a similar number of contacts at the outlet.

you are familiar with the most popular schemes installation walk-through switches.However, the number of such devices do not necessarily have to be limited to two or three.If necessary, a scheme can be expanded to include the required number of devices.Procedure is the same for all cases at the beginning and at the end of the chain to the flow established by single switch with three pins, and the intermediate elements as devices used cross with four contacts.

Set the switches to control lighting from three different places

If resettlement system for lighting control from two different places usually no problem, becausethe scheme has a simple form, the installation of the three switches can cause certain difficulties for the unprepared installer.

We will consider how to set up a system of two walk-through and a crossover switch.By analogy, you can assemble a chain of more devices.

Before proceeding with any further work, turn off the electricity.

To do this, get in-house electrical panel or in the board at the site (for apartment owners), the corresponding switch.In addition, make sure there is no voltage in the circuit breaker is carried out using a special screwdriver indicator.Also, do the same test in the field of installation of devices.

Preparing cutting grooves and niches

To set the switches, we must first prepare the wall Stroebe for laying electrical cables, wires and powered hang on to their placements installed devices.

For shtrobleniya concrete walls it's best to use a hammer.If the walls are made of limestone, deepen better do with the bit, becausein a similar material from the gun will remain too wide and deep cutting grooves that make fixing wire difficult and will require more consumption of cement or plaster in the future.

For shtrobleniya walls of brick hammer is not recommended - can be cracked brickwork.In this situation, the only safe solution is the installation of cables in pre-fitted to the joints between the elements of the masonry.

Wooden wall not Stroebe - wires are laid in special protective boxes.Most often, the cable is pulled under the baseboard and is displayed directly below the breaker installation site.

first step. work begins with the connection of wires to the switch board.No difficulties at this stage, there should not be - modern devices can start immediately to 8 and more wires.

important point!Previously, we need to determine the optimal cable size.Domestic power can hardly be called stable.The current strength in them constantly jumping, and in moments of overload and completely rises to dangerous levels.To avoid problems with wiring, use copper wire cross-section of 2.5 mm2.

second step. Choose a comfortable height of installation switches.At this moment the focus entirely on their own preferences.

third step. defined the height of installation switches, proceed to shtroblenie.By Width and depth do 1.5 times the diameter of the wire.

important point!Wires are routed to the bottom switches, so settle in Stroebe 5-10 cm below the points of installation switches.This requirement is important from a purely practical side, becauseunder similar conditions to work with cables easier and more convenient.

fourth step .We put wires in Stroebe.Fix a wiring elements with small nails.We are trying to drive nails into the wall so that they propped up the cable and do not let him fall.Before attaching the wires, we need to have them in podvyklyuchatel (installation box).This point is considered in the main section of the instructions.Grooves plaster after setting all the switches, ensuring system availability.

Fifthstep. Make holes for the switches size are used appliances.

pass to the milestone.

Set switches

first step. Set up wires from the junction box in podvyklyuchatel.Cut the cord so that the mounting box left about 100 mm in length.This will help us side cutters or pliers.With the ends of the wires remove approximately 1-1.5 cm insulation.

second step .Set pass switch.phase cable (in our case it is white) is connected to the terminal with the label in the form of the letter L. The remaining two cables connected to the terminal which is marked with arrows.

In your case, the color of the cables may be different.You do not know how to perform the laying and connection of the wires in the terminal box?Then do the following.Turn off the electricity and get the phase.You will screwdriver indicator.Phase cable is energized.That's it and connect to the terminal with the letter L, and the other wire arbitrarily connected to the terminal which is marked with arrows.

third step .We carry out the installation of the cross-switch.To him supplied 4-wire.We have a pair of cables each of which has a core with blue and white colors.

understand the manner of marking the terminals on the switch.Above we see a couple of arrows aimed "inside" of the device, at the bottom, they flock "of" it.

to the terminals at the top we connect the first pair of cables from the switch-through previously installed.The other two cables are connected to the terminals at the bottom.

to find live cables, we include electricity and in turn find phase.First, we define the first, changing to this position of the first passage of the switch.The next phase is to find the cables cross the switch.Next, we can only connect the remaining wires to the terminals at the bottom.

fourth step. Getting connecting the last switch.We need to find in it the cables through which there is tension on the cross switch.We have these cables have a blue and yellow color.We connect them to the terminals marked arrows.It remains white cable.It is connected to the terminal which is marked with the letter L.

procedure for determining the cables under tension is already known.In the second case we need to connect the switch to the L-wire terminal at which the voltage is not.

fifth step. Carefully insert the instrument mechanisms mounting box.Wires gently bends to the ground.Fix the device.This will help us fasteners in the mounting box or "feet" clamp mechanisms.

sixth step. Applies the frame of each switch and fasten the clasp of her kit.

seventh step. Mount switches keys.

switches keys At the end we have to connect the lighting fixtures to the wires extending from junction boxes, check the correct operation of the system and repaired Stroebe.

Successful work!
