Switch

[Chrisdoc]

Hi. I am pretty comfortable with electrical wiring and am trying to wire a switch on a bed lamp. Have just never seen anything like in the picture before. Do I join two wires to each terminal to make the break or let one wire run through uncut and the other wire cut and connect to either side of the terminals? I tried to buy it but my local electrical shop said " just wire it yourself".

Yes -Let one wire run through and cut and connect the other to the terminals to make the on/off connection.

 

If possible have the live on the on/off wire.

Those switches are a bit fiddly to get the two wires inside but it's possible as long as the wires aren't too thick.

Thanks Daffy. I went to the d.i.y bible google and went through with the uncut wire. Great to have the verification from you. Cheers.

And a good reminder to always to pull the plug before fiddling at the lamp even when "switched off".

Could still mean that one side at the socket is live (50/50 chance).

Just as an extra bit of information.

 

I wired all the sockets in my house with the live on the upper hole.

 

Most twin flex wire/cables have a tracer of some sort running on one of the wires so it's possible to identify the difference between the two strands.

 

I always use the strand with the tracer as the  "live" and wire up plugs accordingly so when plugging in the socket make sure the "live" goes in the "live" of the socket.

 

If the tracer on the twin flex is not obvious a dab with red marker pen on the plug will identify which way to plug in the  Umm! … plug

That's all good and well.  But, if you are dealing with something that has a 2-prong plug, it just doesn't matter.

I have wired it with the screw facing down making the right side the hot wire. I was going to check the outlet with a testing screw driver to make sure the right side is the hot side. Once I have put the plug in there is no reason for anyone to move it but to be sure am going to superglue it in. In that case it will make a difference as daffyd said, even though is only a two pin plug

If you get the Haco 2-pin plugs they are polarised (neutral is the wider pin) and the flex hangs down parallel to the wall if the outlet has neutral at the top.

 

These chaps Haco P001 :-

 

 

With it's 3-pin friend the P002 :-

 

 

Makes for a nice neat job. We have these all over, they are a lot more robust than they look.

 

Get them in HomePro, MegaHome, even Tesco.

That's true in a lot of cases especially where you buy something that already has a 2 pin plug attached.

 

But in some cases, like the OP wiring up his own lamp, it can be safer to know which is the "Live".

 

Switching the "live" ensures that most of the wiring and the lamp fitting it's self is not "live" and therefore less likely to kill you or the dog or cat should they want to chew through it.

 

Another point when wiring up for a screw in lamp I always connect the "live" to the terminal at the bottom of the holder where the bulb sits, not to terminal that would make the screw thread "live".  

 

Again does not really matter, the lamp will still work but makes me feel better.

I bought one of those, but when I got home found that when plugged in the wire outlet for the plug was at the top.

 

Not very convenient as all my outlets are about shoulder height. ?

To fix:-

• Turn off the power.
• Remove the cover from the outlet.
• Undo the two fixing screws.
• Rotate the outlet 180^o.
• Replace the fixing screws and cover.
• Turn on the power.

But you already knew that Daffy 

 

Also, having the neutral at the top is "safer" in the event you drop something metallic down the back of a plug that's not quite in (no sheathed pins here), it will hit the neutral first.

 

Our outlets are a random mix, the ones where I have Haco plugs have been orientated so the neutral is at the top.

Yes I did  

 

Thing is some time ago when I installed the power outlets I wasn't completely and totally integrated into the local way of doing things and in my naivety installed the boxes in what I thought was the correct way with the "UP" marker on the boxes pointing Errrm - UP. 

 

This has led to the unforeseen result that all sockets are wrong for the Haco plug, but doesn't really matter as I only bought it cos it looked pretty but up to now have had no use for it.

 

Incidentally at the same time I also connected all wiring to the sockets according to the markings on them - L to "Live" and N to "Neutral"  ?

 

Just waiting for that to silly idea to bite me in the nether regions

Thanks. Have already bought and made but next time.
