Relays, Contactors & Solenoids are electromechanical switching and actuation components that use electromagnetic force to control electrical circuits or mechanical movement. They provide an interface between a control signal and a controlled load, enabling controlled connection, disconnection, or motion through electrically driven mechanisms.

• Relays are electrically operated switches that open or close contacts in response to an input signal, providing controlled switching and electrical isolation between control and load circuits.
• Contactors are heavy-duty electromechanical switches designed for repetitive switching of electrical power circuits, using an electromagnetic actuator to operate multiple contacts.
• Solenoids are electromagnetic actuators that convert electrical energy into linear mechanical force or motion through a movable plunger or armature.

This category covers devices intended for reliable electrical control and mechanical actuation within electromechanical systems.
