The Cliff jacks *are* switching jacks, but on most modules they are 
not connected as such. Doepfer often say a signal is 'normalled' to 
some other signal when it is used in a switching capacity. A quick 
scan of the modules I have revealed these: 

A108 'feedb' - from 48dB output if no plug inserted
A110 'CV1' - from bus
     'sync' - grounded
A127 'ext CV' (x3) - from internal LFO
A134 'audio in 2' - from 'audio in 1'
A136 'ext level' (+ and -) - from +L, -L pot resp.
A140 'gate' - from bus
A156 'trig in' (x2) - from internal clock
A179 'ext LDR' - from internal LDR
A199 'ext feedbk in' - from 'reverb out'

... and there are probably more in other modules I don't have!
