Switches and sensors play a critical role in automation systems, enabling precise control and monitoring of various processes. In automation, switches are used to detect specific conditions or trigger actions, such as starting or stopping machines, controlling lights, or adjusting settings based on input. Sensors, on the other hand, detect physical parameters such as temperature, pressure, motion, or proximity, and send this data to a control system for processing. Together, these components ensure that automated systems operate efficiently, reliably, and safely, offering greater flexibility and accuracy in a wide range of applications.
