How to connect a chandelier to a two-button switch: a step-by-step briefing
Even the most original lighting fixture needs power. To save on the electrician's service, you can sort out in detail how to connect the chandelier to the dual-key switch and do all the work yourself.
And two buttons allow you to control the amount of light according to your wishes.
Two-level light control
In one room, the brightness of all 9-12 light bulbs is not always required. Sometimes you want to create a romantic atmosphere, including 2-3 lamps of refined chandeliers. They will allow you to get a muffled light, ideal for holding intimate conversations in the evening.
The subtlety of control of light bulbs depends on the switch - if you put a two-button, you can effectively differentiate the possibilities of the chandelier, forming 2 light groups.This technique allows you to create a deeper light composition.
In addition, the user also receives additional benefits in the form of savings:
- electricity when turning on one small group of light bulbs;
- the resource of the lighting devices themselves, resting for a certain period of time;
- space on the wall - a double model of the switch takes up less space than two single.
And if you wish, you can personally do the connection of the chandelier. To do this, you first have to choose the most suitable model of the switch from the variety offered by numerous manufacturers.
A suitable keyboard and its correct connection will simplify the control of the light in the room. True, still need to create the optimal group of bulbs that make up the chandelier.
In this matter, everything will depend on the number of points that emit light, and the presence of additional lamps in the room. And the model plays not the last role: if it is a multi-level product, then it is advisable to connect one of the keys to the lamps of the upper floor of the chandelier, and to the second - all the rest.
Groups can be formed at will, but the total number of instrument lamps must be taken into account - the more there are, the more variations you can create. So, for a product with 12 light emitters, the following options will be relevant:
Less than 3 lamps for one key to connect does not make sense - the room will be quite dark. 3-4 items are enough for communication or watching movies.
The last option with equal distribution is not the best, because with 6 light bulbs it is inconvenient to read, knit or embroider, and they use quite a lot of electricity.
Step-by-Step Instruction on Connection
When the switch is purchased, and in the new chandelier it was possible to form 2 groups of light bulbs, each of which will be controlled by its own key, you can proceed directly to the electrical installation. It is important to pay due attention to personal safety.
Preparation for installation
The first step is to deal with all the wires. And they can be very much. In order not to get lost and not to confuse anything, we have to calmly examine them and determine which one is responsible for what.
You can start with the chandelier itself. She will have wires going out of each cartridge and there can still be a central conductor. It all depends on the model.
If this product is a trusted manufacturer that values its reputation and customers, then the package will contain instructions. It is her recommendations and should be followed when conducting work on the connection.
Lighting fixtures made by Chinese firms look no less attractive than chandeliers of famous brands. And their cost is much more attractive, which explains the popularity among consumers.
A significant drawback is the lack of instructions with the wiring diagram and the marking of wires. Often, they can all be of the same color - you have to independently determine who corresponds to which.
For self-assembly of all variants of the connection of the conductors, it is more convenient when connecting a chandelier to use PPE caps and Vago terminal blocks.
The remaining methods are relevant for professional electricians who have the right tools and skills to carry out such work.
You also need to determine the ownership of the wires coming from the switch. They can stick right out of the ceiling. Or they will have to be released by removing the old chandelier.
In any case, it is important to de-energize the line before carrying out work in order to protect yourself from electric shock.
After removing the old lighting fixture and freeing the wires, they are to be carefully examined for damage to the insulation. If it is not broken, then you need to separate them in different directions and turn on the power to check with the indicator screwdriver or multimeter the belonging of each of the cores.
Now you need to turn off the power line to carry out further work.
Check the correct connection of the switch
It is important even before installing the chandelier to see if the working mechanism of the switch with two keys is correctly connected.
To do this, you have to remove the front panel with the keys and get the main part to which the wires are attached.
Depending on the model and manufacturer, a two-button keyboard may have various markings on the back that indicate the purpose of the contacts. If there is an instruction, it will be easier to understand, and if it is not available, you need to carefully study the numbers or letters printed on the reverse side.
At independent installation of the switch it is important to connect wires correctly. If it already stands, you need not be lazy and unwind it in order to assess the adequacy of its connection.
When you reach the working mechanism, you need to inspect the insulation, check the correctness of the connection of the wires so that the power supply from the shield is in contact with the letter L. And you should pay attention so that it does not fall out of its connector and nothing dangles.
The working mechanism of the switch, wires and connections must be neat, insulation in the right place. It is important that all the conductors be separated and carefully laid in the bottom plate, if it was used for electrical installation.
Powering the wires
Checking the wires from the double-button switch to the chandelier, you can continue to connect it. In principle, the color of the wires coming out of the working mechanism makes it clear which wires stick out from the ceiling.
They will have to be connected to the nodes formed from the veins emerging from the lighting device’s horns.
To do this correctly, you need to safely perform the connections, well stripping the insulation.
All work is desirable to perform in protective gloves. Even a beginner can use WAGO or PPE caps. Moreover, the installation will be performed under the ceiling, which is not very convenient.
When all connections are made, you need to carefully place the wires, putting them inside the decorative trim lighting device.
It remains to attach the chandelier based on the features of the model - hang it on a hook or fasten it to the bracket.
Common connection errors
When self-wiring often have to deal with issues that arise due to errors made in the connection process.
A common problem is an idle or improperly working chandelier, which must be controlled by a double keyboard.
The first thing you should pay attention to is zero. He never comes to the switch - from the junction box he goes directly to the ceiling. If this is not the case, then you need to correct the mistake by dropping a zero from the box to the chandelier, bypassing the double-key.
The second error associated with the neutral wire, when it was connected to one of the phase connectors. We recall the rule that zero immediately goes to the lighting device and remove it from the phase contact.
The third error - the incoming phase conductor is connected to the outgoing left or right contact in the working mechanism. Simply put, in the process of connecting the connectors got mixed up. It is easy to fix - you need to unscrew the connections and insert the wires correctly, re-securing them.
In addition to these errors, these are often found:
- poorly made connections - the wire dangles without providing proper contact;
- the conductors are simply twisted between themselves and wrapped with tape over the top - simple twisting is prohibited, you should wear a cap or insert them into Vago;
- conductor insulation damaged;
- when performing connections, the insulation was poorly removed, which prevented the creation of tight contact wires.
All problems can be avoided if you immediately perform each of the processes calmly and not be lazy to double-check the quality of work.
It should be noted that the power cable to the chandelier from the switch does not always pass through the junction box. Variants, when the phase goes immediately, bypassing it, is now gaining momentum.
In such cases, to hide all the connections and wires, you can use an additional socket, which is put a plug, though not all manufacturers have such a design.
