  Mechanical: man or motor powered, bars cams, wheels
 Electric:   Relays, steppers, solonoids and contacts has logic tree.
 Electronic: uses active devices, tubes, transistors, ICs some types of    
          diodes and neon filled tubes. 
A good definition, I could agree, althrough I've seen
Electric and Electronic the same, since a relay isn't
diferent from a transistor or a tube for the effekt
(beside the current).
