I bought a single outdoor switch 2 way 20AX from BnQ for a light in the
garage. I want to put a switch by the door for the light and I am not
sure how to connect the live and neutral wires.

On the back of the switch it has COM with a small single black wire
going to another of the same from a single plastic junction thingy and a
wire from 2 way going to the same single plastic junction thingy.

It also has 2 way and a way socket or square hole.
Do I connect the live into 1 way and neutral into com.

Thanks

Just to clear things, are you simply replacing an indoor switch with an exterior switch? If so then simply connect the wires as before to com and the 1- way terminal. Chances are what you think is neutral is a switched live that should have been sleeved red. A photo of the existing switch and the innards of the junction box would help to give a definitive answer.

Thanks but no it is not a replacement but a new install, as we have just
had electric put in the garage.
As I'm not an electrician, I want to be sure where to put the wires in
the new switch.

I did wonder if I had bought the wrong type of switch.

Have you an existing lighting circuit in the garage? If so a description plus some photos of the wiring in any rosettes or junction boxes would be helpful. If this lighting circuit is a complete new install then I would strongly recommend that you consult the uk.d-I-y wiki first as this could become a very long description.

OK just had a look on the B&Q website and cannot find one with the code numbers you have given, but if it is the Diall 1 gang 2 way 20A external single outdoor switch with the small neon at the top you can ignore the wires inside as they are only for the neon indicator.

Is it this;

If not include the web page address of the correct switch in your next post

Perhaps you could describe what you've had put in ...

Just a raw electricity supply? with or without a consumer unit?

A full installation with sockets and lights, but you're looking to add
an outdoor switch to the existing light?

Something else?

OK this is rather hard to answer as there are a few two many variables
here...

Firstly do you need a two way switch (two way switches are typically
wired in pairs to allow a lamp to be switched from more than one position)?

If the answer to that is "no", then don't worry - you can still use the
switch on its own to switch a lamp, you will just have a spare terminal
on the switch you won't need.

Two way switches are just changeover switches. In one position they
connect like:

http://wiki.diyfaq.org.uk/index.php/...Convention.png

and in the other:

http://wiki.diyfaq.org.uk/index.php/...onvention2.png

So if you just want a regular on/off switch you use the COM terminal and
either one of the others.


On the back of the switch it has COM with a small single black wire
going to another of the same from a single plastic junction thingy and a
wire from 2 way going to the same single plastic junction thingy.

It also has 2 way and a way socket or square hole.
Do I connect the live into 1 way and neutral into com.

ok take care here - if you actually have live and neutral, you really
don't want to switch them together - at best you will trip a MCB / blow
a fuse, and at worst knacker the switch.

I am not really able to make much sense of the description, so lets go
from first principles...

First, go and look at this section:

http://wiki.diyfaq.org.uk/index.php/...nners#Lighting

Now each of those show ways in which a whole circuit is wired - i.e.
several lamps and switches. In simple cases there may only be one switch
and lamp, and hence there is no need for the added complexity of running
a power feed onto the next lamp position.

If you just have lamp and a switch with a mains supply, the simplest way
is to connect the neutral of the supply through to the lamp, and place
the switch in the live wire. You can use a screw terminal (aka chocolate
block) connector in the back box of the switch to join the neutrals.

Could you not deduce it by using a continuity tester of some sort?
