you're going to like today's video have your college and college lecturers been misleading
you about lighting circuits we'll get to that in the video on the channel we've looked at lighting
circuits in the form of the three plate method where we had one way two way and intermediate
switching probably something you do in the first six seven weeks when you're at college
i went and developed it to look at the two plate method a method commonly used in installations
when there's numbers of downlights and we looked at one way two way intermediate and
then i built this rig here to help you when you're looking at AM2 and AM2S and this is
wired through the switch and again it's two way intermediate switching of a lighting point
but that brings me back to the original part have you been misled i'm going to convert this back to
a simple one way lighting circuit maybe something similar to what you got in a bedroom switch at the
door and one lighting point and i'm going to turn it then into two way and two way intermediate in
a really short space of time so i'm going to get busy let's come back when i got it back to a one
way lighting circuit it's almost stepped back in time i've gone back to a one way lighting circuit
probably the first lighting circuit we ever carry out in an electrical workshop so let's see
we've got a one gang one way switch yeah you won't be turning it on and off that's probably the first
lighting circuit we've done we get stretched and go on and do two way and then two way intermediate
and how do we do that we end up changing this one gang one way switch for a two way switch
we introduced a three core and another switch two way and then we have a configuration where we have
an intermediate switch and these three core cables between them but not today however there is a few
things we've got to bear in mind before we go on to change this switch for the magic one which
will come next is that i've replaced my shallow depth about 16 mil lighting boxes that we use
at college i've changed it for the ones that we're likely to be using for socket outlets so at least
a depth of 25 mil in the real world in industry you're likely to be chopping light switch boxes
in that are already 25 mil or using dry line boxes which are greater than 25 mil and therefore this
in-line receiver we're going to see in a minute works perfectly so this is it here still boxed up
because i'm keeping it secret for the time being so this in-line receiver works on kinetic energy
kinetic energy now i'm sure we've heard that before in an electrical science and principles
lesson kinetic means when motion so when there is motion it creates energy and that energy will send
a signal and that will be a radio frequency signal in order to operate the switches when we introduce
them it's made by Quinetic so that's the brand i'm using this in-line receiver all we have to do find
the boxes at the right depth 25 mil deep or bigger is take off your one way switch and replace it
with this one and then you can pair an additional five switches that have no cables and they have no
batteries they work on this kinetic energy however before we do change that switch out in the real
world you're going to need to produce your voltage indicators your proving units your locking off
devices your signs etc and i've done the safe isolation procedure many times on the channel
so let's make sure that we're working safely i'm just going to disconnect mine from out of here
and move it into a central position so i can show you the connections in this in-line receiver
so if you're thinking about it you might be thinking now in a minute when i've seen this
i can go on and change maybe the switch in my bedroom which is just one at the door turning
on my light i could change it with an in-line receiver from Quinetic and therefore i could
have other switches in my bedroom controlling the lights and you are right but let's make sure we
work safely and do that safe isolation procedure as i said we've shown it on the channel many times
so i'm going to swap this one over i'm going to show you nice and close and lay it flat and then
we're going to go through the pairing process and i'm going to change this one way lighting
circuit over to two way and then two way and intermediate safe isolation being carried out
and now you're ready to change in this case a one gang one way switch so we've got our permanent
line and our switching line we can see it's not a neutral it's identified with the brown sleeving
as our switching line and what's brilliant about these in-line switches from Quinetic is they do
not need a neutral so i've got exactly what i need a permanent line and a switching line and
i'm going to replace this switch for one that has a receiver in it the receiver has to be powered
so hence we need to supply to it it's the other switches that will be working on the
kinetic energy when we introduce them so we'll open it up and we're getting out of the packet
something quite satisfying about opening new stuff and there we have it so that's our switch
so we've got our two connections here and here so we're going to have our permanent line and
our switching line connected we've just got to pull the front off in order to screw it down
so disconnect my permanent line conductor obviously comes out of there and then my switching
line conductor you'll notice the box is deeper and i've had to change it for deeper box this is a
single socket box hence there's no connection for the CPC so i've had to use a Wago 221 connector
to hold that in place and again in in the real world that box is like to be a dry line box or a
flushed in metal box into the wall and now we've got to make our connections and you can see it
we've got an L connection for a permanent line and our L1 for our switching line connections we have
to separate the two so this is going just be a bit careful just to pull the switch front off the body
so it should just come away with a gentle little wiggle as you go so i've separated those two
and that gives me my two fixing screws when i need them in order to hold it into position
so i've just gotta make my connections on the back now so L being my permanent line connection
like there and then my switching line remember that is not a neutral
it doesn't need a neutral which makes it fantastic lots of times there aren't neutrals at switches
so i'm going back when i've got this connected this will be exactly the same as it was before
a one way switch operating that light and we'll introduce some more switches so we lay that into
position onto the box and then we can screw it down then we can reintroduce that cover
it is important you get it on the right way around because obviously you want down to
be on for the switch the bit in the back that we've connected to is our receiver
so then we'll be able to pair some more switches to it but let's see it first of all once we've
got it back together as a one way switch that's held into position got to bring in our cover and
just reposition that back onto the to the switch get it to clip into the right place
and there we go so we so that's a switching mechanism press it down to turn the light
on and off so we'll power it back up and we'll see it as a one way switch first
so it was super simple and now we've just got a one way switch so that's fine but we said
we want to introduce other switches we're not going to use cables we're going to use
this kinetic energy that sends a radio frequency that's picked up by here where the receiver sits
in order to turn these on and off so we'll see how to pair some other switches in the next part
these switches need to have at least a 5 watt load i've got a 7 watt lamp on mine but if you
think you've got a fancy light fitting with more than one lamp in it five watts is fine that's the
lowest wattage range that it will switch it will switch up to 600 watts of LED or 900 watts of load
but we're interested in obviously now the pairing process and see how simple that is
so i've introduced another very similar switch you could stick this or screw this to the wall
my daughter has left this loose on her bedside table in order that she can turn her lights on
and move it around which i think is also a nice touch so you could use some tape on the back here
and stick it to your wall or you could fix it into position but we'll just have it freestanding in
a minute but at the minute it doesn't do anything so it's not operating the light but this one is so
we've got to bring it into pairing process which is about a six second hold so push it and hold it
for about six seconds and then it should start to flash when it starts that flashing process
it will be in pairing mode there we go so we're in pairing mode we take the switch we want to pair
and we operate that switch that uses kinetic energy
and you now see i'm turning that light on and off with these two switches so that's become
two way switched by pairing that switch so this switch now can be taken away it can be 25 meters
indoors so that's with obstacles like doors and walls in that in a way i think our bedroom's going
to be under 25 meters uh in the area size and a distance of 80 meters outside in other words in
free air so i don't think we can have an outside one but these are IP rated so i suppose you could
but i'm looking at this with this receiver being installed inside where there's a one way switch
allowing you to put two way switching in look how simple that was that's something they didn't
teach you at colleges and that that's now two way switched how does this work there is no cables
there are no batteries in here by operating the switch it creates kinetic movement which creates
energy which sends a radio frequency through the air which is picked up by the receiver
and the receiver changes it from either on or off depending on the position it was last in so
we come back on off we've now got two way switching they do some different designs of
these switches i've got another one here very similar but different colour so again there's
a switch there but it's gray we've got this one here which is quite handy which is a grid switch
so again this is a grid switch and we've often seen especially on site things like this yoke
here or grid mounting frame and we can position those in there so that could be paired to it
and that's quite handy if you had a two gang version of this and had a standard light switch
and then you introduced a Quinetic switch for something else in the room and i've also done that
in installations as well and possibly my favorite believe it or not that is also a switch you can
pair which looks remarkably like most people's key fobs in order to open the car okay so we can
pair those so i'm going to make it two way next and intermediate so we've got two way
so i'll introduce the grey one to give us three switches so let's just confirm
we have two way so how do we set it into pairing mode exactly the same as we did
before we press and hold for approximately six seconds until it starts blinking
and there we go so about six seconds and then that blinking process will go so it starts to flash
and then you come in with your other switch you want to pair
and you now find i'll move these out the way we can go on off on off on off
that is fantastic so effectively we have now got two way and intermediate switching well we haven't
got any cables between them we're sending that radio frequency picked up by the receiver by using
movement of kinetic energy to send that signal no batteries no cables so that's now got three
switches shall we pair the key fob one just uh just to have a look at it exactly the same process
press and hold press and hold for three for six seconds until we get that where it starts to
to flash or blink it's into pairing mode we bring in our key fob
so we go key fob switch switch so which key fob all of those are paired and we could go on and
continue the process on so at college you're taught one way two way intermediate and it's
vitally important you also taught the two plate the three plate and the wired through the switch
method of wiring lighting circuits we've shown on the channel but out there in industry there
is nothing stopping us using this sort of system here to quickly change in a bedroom in a i don't
know any house room that you could choose but i always think of the bedroom you move your
bed around all of a sudden the switch isn't in the right place you want a two way switch
all you've got to do is change the switch at the door and introduce one of the other switches and
you can have up to five other switches so in this case we've got four switches so it's this switch
and five others which makes six okay that you can have in that area in order to use those so that's
by installing a Quinetic in-line receiver replacing your one-way switch just a simple
changing over the connections and we had permanent line and switching line that's your receiver and
pairing these switches in here and as always i hope this video has been some fun been some help
