However, the basic difference between the relay and contactor is that the contactor is used in applications with higher current carrying capacity, whereas the relay is used for lower current applications. It is the first contactor used to control an electric motor in the late 1800s. Allows current to only flow to the right.

What Is The Function Of A Contactor?

Switch contacts (electrical switch contacts) make or break an electric control circuit dependent upon the pointer position of the indicating measuring instrument. In simple words, electrical contactor is an electrically operated switch whose main function is to connect or disconnect the load from the power source. Mercury switches use a slug of liquid mercury metal as a moving contact.

For All Intent Purposes, A Contactor Is A Relay, As Shown In Figure 2.

As mentioned before, a contactor is an electromechanical switch used primarily for opening or closing electrical circuits. Typically a contactor is activated by a remote switch or other controlling electrical device. Most of the contactors operate by electromagnet, thus causing the contactors to close and open by spring or gravity.

Electrical Contactors, As Shown In Figure 1, Are Switches That Are Turned On And Off With Electrical Power Rather Than With The Direct Push Of A Button Or Flipping A Toggle Switch.
