Electromechanical devices bridge the electrical and mechanical realms, enabling control and interaction with physical systems. Relays, acting as electrically controlled switches, manage power flow to motors or other loads. Solenoids convert electrical energy into linear motion, commonly used in valves and actuators. Motors, including DC and AC types, provide rotary motion for diverse applications from fans to robotics. These devices often incorporate sensors for feedback, allowing for precise control and automation. Their robust nature and ability to handle high power make them essential components in various industrial and consumer products.
