The term "contactor" usually refers to the relay that carries the main
current supply to the starter.  This is already built in to the starter
(solonoid).  True, the contactor or solenoid takes a good bit of current to
actuate but a separate relay to handle this seems like unnecessary
complication when a *PROPER* switch will do the job.  Just haven't heard a
compelling reason why this relay is necessary.
