Hi, short answer is you can't!
the sw only has a permanent live in and a switched live out to light. no neutral.
so you have to run twin & earth to your light and connect to the same terminals as the lamp holder, also you must connect the earth in with the others in light fitting. as in a bathroom this is not legal DIY & if room has no window ie no natural light it should also have seperate local isolator sw. so light can be on while servicing 'dead' fan
