2Pin to 3pin Plug

Iconic

I want to replace a 2pin with a 3pin plug.

I have done it in the past with no problems but I now get worried with all extra information displayed on the plugs.

Could some please explain these specs on the 2pin plug

'Input 100-240v-50/60Hz 0.3A
Output 9V 0.6A

ITE Power Supply'

I know the UK standard Voltage is 230V so that is ok but I am unsure about the rest.

That looks fine. It shows the range of voltages 100 to 240. Also the acceptable frequencies, we are 50hz.

you aren't going to get 9v out, unless there is a transformer on it. What's it for.

why not just use an adaptor, from a pound shop

Googling for "Change 2 pin plug to 3 pin" will give you instructions, BUT:

The fact that it has a 9 Volt output, makes me think that this is for some kind of transformer, say for a cordless power driver, a modem/router, or similar. If so, the 2 pin plug will have dedicated internal electronics for this feature. DO NOT change these plugs, yo may cause damage to circuits or whatever you intend to power the plug with.

Yes, but he's about to chop that off and replace it with a simple mains plug :eek: :eek:

Its not a plug, its a plug in power brick, with a 9v output.
Use a two to 3 pin adapter, or buy another power adapter.

Phew glad I asked before I did it.

It's a TP link 5 port 10/100Mbps Unmanaged Desktop Switch that splits connections to my tv,dvd and skybox. I bought it about a year ago but it came with a 2pin plug. I have been using an adapter like the one above but I am trying to tidy up the wires at the back of my unit and a 3pin plug would be much better. I think I will leave it as it is now!

Loud bang avoided!
Pleased the replies helped.
You should be able to get a UK adapter for your switch if you really want one.

Many years ago a lot of radios were imported from the States, to match our mains 230v, whilst theirs was 110v, they were fitted with resistive mains leads. Some users thinking them untidy, shortened them with disastrous results.

But I am still confused!

I changed my razor's 2pin to a three pin many years ago and I am still alive.

They supply these switches with three pin plugs..mine is an earlier version but is more or less the same as this http://www.amazon.co.uk/TP-Link-TL-SF1005D-100Mbps-Unmanaged-Desktop/dp/B000FNFSPY

I don't know why they sent me a 2pin. However if there is some kind of transformer in the plug I am sure it's not in the 3pin version.

What loud bang ?

If the op is already using an adapter then thats just the same as cutting off the 2 pin plug and fitting a 3 pin plug.

All an adapter does is change the shape of the plug so it fits in the wall socket.

If it wasnt safe to do then why can you buy adapters?

...because this seems to say there is some kind of transformer in the original plug. Cut off the old plug and you remove the transformer and get a loud bang!

However this does not explain why these units are also supplied with 3 pin plugs. Where is the transformer then?
