hello everyone welcome back to my
channel this video is about two-way
switching or wiring to two-way switches
together if we want to control one light
from two different locations this type
of wiring is usually used in a long
hallways or on the staircase well we've
got one light and two switches that
control it one from the bottom of the
stairs and another one from top of the
stairs here you see a consumer unit on
the right and in the middle of three
lamps with a sitting closest so this
would be a lighting circuit with three
lamps each in a different room for this
circuit we're gonna use flat twin an
edge cable with brown light wire and
blue neutral wire cable from consumer
image rounds to the first lamp ceiling
groves and ten from the first lamp to
the second one and from the second to
the third and if the circuit is radial
it finishes at the third lamp to control
the lamps we need to add one way switch
to every lamp in every room so now the
lighting circuit is complete and each
one way switch controls one lamp but
let's say the first lamp is on the
staircase and we want to control it from
two switches one from the bottom and one
from the top of the stairs to do this we
need to replace the one way switch with
two a switch and also add another two
way switch and then link them together
with free core unaired cable as you see
this cable wires are different colors to
the wires that we use so far this one
has got brown black and gray instead of
just brown and blue
here is a sample of one way switch and
to a switch the front looks the same but
they differ at the back one way switch
has got two terminals come and l1 and to
a switch has three terminals come on l1
and l2 on the next picture you see on
the right the ceiling rose with four
terminals add line loop and neutral and
on the left our two two ways witches
that we need to link together also on
the top you see two twin inert cables
this one on the right is from previous
lab or in this case from the consumer
unit and the one on the left is going
from this scene across to the next one
in a different room so intercity groves
both green and yellow editing wires from
these two cables are connected to the
earth terminal both blue neutral wires
to neutral terminal and both light brown
wires to the loop terminal
now the first which is also wired to the
city grows with twin and out cable and
the city grows earth wired to the earth
terminal life wire to the loop and blue
wire to line terminal and we need to put
brown sleep on it as we switch the
lights on this wire becomes life as well
at the first switch the earth wire goes
to the earth terminal that is usually
located inside the back box not on the
switch like on this picture so you need
to find it and wire it there the brown
wire goes to l1 and the blue wire goes
to l2 now we need to link these two
switches together so we need to use
three core and add cable at the first
switch at wire goes to earth terminal
Brown 2 L 1 grade 2 L 2 and black to
calm terminal at the second switch we do
the same colors to the same terminals as
the first switch earth wire goes to a
terminal Brown wire goes to L 1 the gray
wire goes to L 2 and the black wire goes
to calm terminal and we took put the
brown sleeves or black wires or gray
wires and the blue wire at the first
switch as well and that's it for today
all the wiring is done if you like my
