switch to set the required switch:
switch Connecting directly to a lamp - this thing is very simple to understand even a schoolboy, but can not yet forget the main rule - the phase wire is connected to the lamp by means of the switch, ie,phase is always connected to the gap.It must be observed for the safety of continued operation of electrical appliances.Otherwise, if the switch is not off from a network phase and zero, the cables remain always under stress, and it is very dangerous.Phase wire is determined using the indicator and connect it to the bulb so that it was connected to the central terminal phase.
But how to connect through a single junction box wire from the lamp, switch and guard, then we need to understand.
switch consists of:
With the electrical panel to the box leaves the cable consisting of two wires.It is better that they are of different colors.Further, this same box suitable wires from the switch and the lamp.Phase of raspredschitka usually red and respectively connected to the red wire to a suitable switch.Blue wire from the switch is connected to the red that is connected to the lamp, thereby making phase switched.
Zero blue wire from the switch board is connected to the zero, marching on the lamp.As a result, from zero raspredkoroba goes directly to the bulb, and the phase is connected through the switch.It turns out that when you press the switch button, the circuit is completed, the phase is supplied to a light bulb and it glows.At the conclusion of all the exposed wires carefully isolated and fit neatly in a box.For greater reliability of connections can be applied in addition to twist even soldering.
If the apartment there are common junction boxes, which are connected to all sockets and switches, then figure out what is connected and what is difficult.For example, if a junction box is connected with the switch on the lamp and socket.
In this case, from the panel to the box are two cables - one red with the phase and the other blue with zero.a similar connection scheme as described above.The socket is connected in parallel - phase to phase (two red wires), zero to zero (blue wire).
We have considered a brief digression, how to connect the sockets and switches.If you still are unknown points, then pay attention to the video and photos.And remember safety.
