A contactor is essentially a switch that can control the connection and disconnection of electrical circuits, using low-voltage signals to manage high‑voltage currents. It is commonly employed in automated control circuits, where it performs functions such as automatic regulation, safety protection, and circuit switching. Additionally, it can detect faults in the power system and open the circuit to prevent further damage.
