Magnetic contactors, like electrical contactors, are made out of contacts that may open and close to regulate electrical circuits. However, magnetic contactors employ an electromagnet or permanent magnet that is activated by the current passing through the contacts itself to actuate the contacts rather than depending on an electromagnetic coil. As a result, the contacts in this self-sustaining system stay closed as long as the current is passing through the circuit.
