Electromechanical refers to devices or systems that combine both electrical and mechanical components to perform a specific function. These devices use electrical energy to produce mechanical movements or vice versa. Electromechanical systems are widely used in various applications, such as relays, switches, electric motors, and sensors, to convert electrical signals into mechanical actions or mechanical inputs into electrical signals. They play a crucial role in automation, control, and the operation of many everyday appliances and machinery.
