If there are no problems with the connection of the ordinary switch, then as soon as you have to encounter the connection of a two-vector or double switch, then the mass of questions immediately occurs. We will try to give answers to all questions, but at the same time, and tell how to connect a double switch.
How to connect the double switch - about the switch device
In fact, if you understand more in all the subtleties of electricians, it becomes clear that there is nothing complicated. It turns out that everything is simple. Newbie, who has never been engaged in installing and connecting switches, we advise first to learn more, how the switch is arranged, which there are contacts and terminals, study the scheme.
Externally, the double switch is practically no different, except instead of one key on the front panel there are two small. Our task to know what is inside. To remove the protective panel, you must carefully remove the protection - use the usual screwdriver. It is just done: on the one hand, it is necessary to carefully pry a plastic lining. It is possible that your switch is equipped with special protrusions, then the task is simplified.
What you need to do next:
- Disconnect the frame. Depending on the type of switch, they can be attached differently: on the screws or on the latch.
- Latches need to press in two fingers and pull on themselves, screws - just unscrew (they are diagonally).
- The frame was removed, now you can proceed to the most interesting - connection.
How to connect a double switch
The internal mechanism of the switch consists of wiring, contacts and terminals - our task to know their purpose to understand where and what to connect.
And first let's deal with what types of switches are:
- in charge or self-consuming contacts;
- normal screw contacts.
We learn more about how to connect:
- Pay attention to the rear wall of the switch - there must be a connection diagram or designated contacts.
- If it is difficult to figure out, then you suggest that the Latin letter "L" and 2 arrows, looking down - this is a phase, a number of 1-phase for washing, and 2-3 - exhaust. If you got a Chinese version of the switch, then this information is not looking for. Most likely it will not be there and will have to independently search for a phase.
- And you can find the phase using a special instrument - indicator.
- If you see arrows located along the edges of the switch, the phase is transmitted sequentially when connected. Suppose, connected a chandelier with two light bulbs - if you turned on the right button - one light bulb caught fire, the left is the second.
- In order to connect the switch, a wire for 3 veins is used, and each of them performs its task. All wires in order to distinguish them - multicolored so that when connected it is not confused.
- From each vein you need to remove the insulation, retreating 1 cm from the tip.
- Determine the wire phase. Check the indicator, under the wire voltage or not - it is necessary that the voltage is missing.
- The wire was cleared - inserted into a special hole, fixed the clamp.
- The outgoing veins are connected in series: right, then left.
- Now you need to install the "heart" of the switch in the opposite. The most important thing is to take into account its size. In the old Soviet type, the modern switch will enter, only there will be no dense fixation.
- Insert the core, tighten the screws and put on top of a protective plastic frame with two keys.
- Switch is connected, you can check the operation.
