staircase lighting puzzle

[firespark]

A 10 floor block of flats has a common staircase.
There is only one light switch in the staircase located on the top floor.
How do you turn the lights on from the ground floor?

Pull cord switch with a hell of a lot of string OR ring your mate on the top floor to turn it on for you

Get someone else to switch them on.

Send a blind person (or whatever the politically correct name is), up to the top.

Should have constant light anyway when dark... Want a quote for free

Yep, a pull cord and a long bit of string!

I'm guessing the answer is that the lights are on a timeclock or photocell so the lights come on automatically.
That way occupants of the flats will be able to see their way up the stairs, without breaching the human rights of any Jewish people who live there, who won't turn lights on on the Sabbath.
