Relays and contactors are electromechanical switching elements used to open and close electrical circuits via a remote control signal. Although both operate on a similar principle based on a coil and contacts, they differ significantly in terms of application purpose, power capacity, structural characteristics, and usage areas. Generally, relays are used in control circuits with low current and voltage levels for tasks such as signal processing, amplification, and isolation, while contactors are
