"A contactor is a electrically controlled switch which uses an electromagnetic coil to pull in the contacts."

"A motor starter is a contactor, plus an overload relay that will drop out the coil voltage if the motor overloads. If there is not overload relay, it is not a starter any longer, it's back to being just a contactor."
