Replacing a switch - which wires???


Postby jjlumley » Sat Jun 23, 2012 5:33 pm

Hi guys, I am new to this forum, but am desperately trying to work out how to replace a switch in my house (replacing lots of switches and sockets with nicer ones)

So the switch is on the bedroom wall outside of the ensuite and it is a double switch. One switches the bathroom light on/off, the other switches the bathroom extractor fan on/off.

I have drawn a diagram of the existing switch, because it's hard to take a decent photo, and below the diagram is a photo of the new switch that I want to use.

I just cant work out the wiring. Help please???

Many thanks, John.

I would say the only way you will get a switch like you show is to get a grid switch. From what you show both live wires (neutral is considered live) are switched as to why is another question. It may have been ease of wiring or it could be a TT supply and someone is playing save.

The switch you show is a 2 pole switch the replacement is a single pole two way switch. By putting the black wires into a junction block you may be able to use it. But the question must be why was that switch used in the first place?

So since your not likely to have the test equipment required to work out if there is a good reason for using that type of switch the easy way is to just keep to using the same type. Grid switches come with all sorts of covers and options google grid switch and come back if that does not help.
