I wouldnt worry too much about the cables for one night.
If they were to touch together all that would happen is the light would come on.
Well the switch line anyway.
If you do anymore please turn the lighting breakers off first.
The better pull switches MK etc have a joiner about 3 inches from the top of the cord so as you can replace it without any taking apart at all
I really would suggest an electrician or handyman.
