There is an alternative format for defining the signature,
shown in this variation of your example:

 \new Staff {
   \set Staff.keySignature = #'( ((1 . 4) . 2)   ((1 . 1) . 2)  )
   b4 c' dis' e' f' gis' a' b'
   c'' dis'' e'' f'' gis'' a'' b''
   \set Staff.keySignature = #'( (4 . 2)   (1 . 2)  )
   b4 c' dis' e' f' gis' a' b'
   c'' dis'' e'' f'' gis'' a'' b''
 }

You can read all the settings there:
