Introduction to Actuators: Types, Functions, and Applications - JSS3 Basic technology Lesson Note

Actuators are mechanisms that convert electrical signals into physical action, such as movement or pressure. Examples include motors, solenoids, and hydraulic actuators. Actuators are integral to automated systems where they control valves, open and close doors, or adjust positions in robotics. In manufacturing, hydraulic actuators precisely control heavy machinery, while electric actuators in vehicles adjust mirror positions and regulate engine components.
