How can I fix a dodgy bathroom light switch?

I have a pull cord light switch in my bathroom, recently it has decided to only work once a day in the morning. The light will come on when the cord is pulled in the morning but then when I switch it off again it will not work for the rest of the day but will come on again when pulled the next morning! It has been like this for the past 4 days. The cord still pulls and makes the clicking noise like it's working but no light. I have tried changing the bulb to a new one and to lower voltage but it was no help. What do you think the problem could be and how can I fix it?
