Title: Describe types and functions of relays.
Course: Technology of Robotic Design (21009-36) > Section: Exploring the Components of Robotics and Automation Systems

Description should include

- types of relays (i.e., double-pole, single-pole, switches)
- functions of relays (i.e., to control power).

Process/Skill Questions:

- What is the function of a relay?
- What are the different types of relays? Under what circumstances should one type be chosen over another?
- When might a double-pole relay be the logical choice?
