AC contactor or AC magnetic contactor is an electrically controlled switch used for switching an electrical power circuit, commonly found in motor-starting applications, heaters, lighting, and transfer systems. It is designed to handle high-voltage electricity and is typically controlled by a circuit with a much lower power level, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.

The AC magnetic contactor consists of a coil or electromagnet, contacts (main and auxiliary), and an iron core with fixed and moving parts. When the coil is energized, it creates a magnetic field that pulls the contacts together, closing the circuit. When the coil is de-energized, the contacts separate, opening the circuit. AC magnetic contactors are widely used in industrial automation and motor control systems due to their reliability and ability to handle high-voltage electrical circuits.
