Contactor is used for controlling the Device.It contain one
energising coil and auxiliary contacts ie NO or NC.Whenever
the coil gets energise its auxiliarry contacts position
changes ie NO become NC and NC become NO.

its an electrical device used for supplying controlled
power supply to electrical equipment along with some other
auxilary contact i.e. NO/NC.or simply u can say its a
distant switching device.it has one magnetic coil,when ever
we give control supply to its coil its get energised &
pulls up main contact for supply leads to make electrical
ckt.again we remove control supply to its coil its de-
energise to release contact.
