Combined extractor fan and light switch connection problem.

Hi guys,

I have come across a single light switch for my bathroom which connects to the bathroom light and the extractor fan. The light switch has 5 live wires going into just two terminals. There are 3 brown going into the L1 terminal and 2 wires (one brown and the other black with a brown sleeve) going into the common terminal. I want to separate the light and fan into a double switch, can this be done with just the wires in the current switch. There are 4 cables feeding into the light box and a terminal block with 4 neutral and 4 earth wires connected to it.

Thanks in advance...

almost certainly yes...

lecky off then disconnect and isolate the 2 wires that are currently in com. (by isolate I mean put them in a piece of connector block not connected to each other) restore
electric. If I'm reading your post correctly then neither the fan nor the light should work.

Report back.

Hi Wine~o

Thanks for the reply but I want to change the single light switch to a double so I can operate the fan and the light separately.

Cheers.

Hi Wine~o

I have sorted it out with a little trial and error and by joining the two common terminals.

Thanks for your help.
