Looking for power cord switch

[royc75]

Hello

I have a wall lamp in the kids room and the switch cord isn’t working (I confirmed that by replacing it with another cord).

I would like to replace the cord which is something like this one

2 Core Switched Power Cord with 2 Meters of Cable

2 Core Switched Power Cord with 2 Meters of Cable, White.

Only the end of it is like in the image enclosed. I cannot find the exact one with the right end. Any ideas or will I need to construct it myself ?

That looks like an "extra-low-voltage" (less than 50V) DC connector. Does this light/lamp run from a "wall wart" power supply? Please post a picture of the complete power cord so we can give you more information.

 

[royc75]

Thanks.

I’ve attached a couple more pictures.

I bought this outside of the U.K. so the plug isn’t U.K. and I use an adapter but a U.K. one will be even better to replace this with.

Maybe something like this:

But you will have to fit a switch to the cord, perhaps you can use the switch from the old one. Getting one in white may be difficult.

NB That cord you linked to in your first post must not be used as it is a 240v cord not a 12v power supply.

Thanks but how do I fit a switch ?

The one I have seems bolted in, it doesn’t go out easily unless I break it.

Would something like this work on top ?

Yes is a wall wart

Best option might be to buy a good quality UK "wall wart" then and join the existing cable from the lamp to the cable coming from the new wall wart,

 

[royc75]

Thank you but again the existing one won’t come off. So would it be ok to buy new wall wart then connect a switch extender to it like this one ?

Something like that may be the simplest solution.
Although personally, I would prefer a non-ebay connector!:

In-line power switch for 2.1mm barrel jack

Add a power switch to any project simply by plugging this between the power supply. This is the most useful thing you never knew you needed! You'll want to pick up a bunch for your electronic projects. Comes with a 5.5/2.1mm barrel jack on one end an a plug on the other. In between is an in-line...

thepihut.com

For a start, this one gives the barrel size (5.5mm outside diameter, 2.1mm inner), and this has to match your existing barrel.

...and even with the correct size barrel, these type of connector sometimes have a tendency to slip out.

An alternative may be to buy a rewirable inline switch (DC rated), it won't slip out, but the coaxial cable from the PSU can be difficult to strip and rewire due to the thin conductors used.

Just to note, you are switching the lamp on and off at the load side. The power supply will still be on and drawing a small amount of current.

the switch cord isn’t working (I confirmed that by replacing it with another cord).

I think that you replaced both the cable and the 12 volt power module as from your pictures the cable appears to be permanently fixed to the power module. If that is the case then it is most likely that the power module ( wall wart ) has failed.

Thanks again

Yes that part comes out indeed with a single screw however I don’t have the right tools to replace it I’m afraid :-/

 

[winston1]

Buy the tool then. Tools are always useful.

 

[royc75]

True but then I need to learn how to use them ))

What should I buy ?

You look at the problem and workout the tool.

e.g A screw requires a screwdriver.

Yeh well I was thinking of a soldering iron for example...

I bought my first soldering iron over 60 years ago to make my first radio constructional project. It's been upgraded several times over the years but hardly a week goes by without me using it.
