Meet the Actuator Family

Run the Meet the Actuator Family MicroSim Fullscreen

About This MicroSim

This interactive infographic compares four electromagnetic output devices by the kind of motion or switching they provide and the driver circuitry they need.

How to Use

1. In Explore mode, click a column—or focus it with the keyboard and press Enter—to reveal a description and selection guidance.
2. Select Quiz Me and answer each use-case question by choosing the matching image.
3. Compare at least two columns and explain which visible and electrical differences matter most.

Compared Items

1. DC motor
2. Electromechanical relay
3. Push-pull solenoid
4. Hobby servo

Lesson Plan

Grade Level

Grades 6–10; beginning electronics

Duration

10–15 minutes

Learning Objective

Students will match continuous rotation, isolated switching, linear motion, and commanded position to the correct actuator.

Activities

1. Explore: Inspect each column and identify a visible clue.
2. Compare: Contrast two choices using the detail panel.
3. Apply: Complete the quiz and justify each selection aloud or in writing.

Assessment

Ask learners to choose an actuator for a wheel, isolated mains control, door latch, and steering linkage, including required protection.
