Contactor is an electro-mechanical switching device which is remotely operated. A contactor should be capable of making, carrying and breaking currents under normal conditions and during operating overload conditions. It is placed nearest to the load center e.g. for Switching motors, lights, capacitors,heaters,furnaces etc.

The main function of a DC motor contactor is simply to make and break the connection between the power source and the load. One side of contactor is fixed and the other is movable. Once energized, the generated electromagnetic force pulls the movable contact toward the stationary contact and the spring pulls the contactors apart once de-energized.
