Contactors are devices consists of E shaped
electromagnectic core with winding are mainly used for NO
and NC connections which means making and braking of
circuit... we can split the flow of current by using
contactors...DC contactors and ac contactors are also
available.. it is used for high rating ... above 110v ac
and dc... But relays are also used for NO and NC changes
i.e making and breaking of circuits but especially for
remote or distant operation.. using 110 v ac supply..it
also consists of coil but absence of electromagnetic core..
there are several types of relays ..ex: industrial relay,
electromagnetic relay... etc
