Switches are fundamental electrical components that control the flow of current in a circuit by opening or closing the circuit pathway. Available in various types, including toggle, push-button, and rotary switches, they cater to diverse applications in residential, commercial, and industrial settings. Switches enhance user control over devices and systems, enabling functions such as turning lights on and off or activating machinery. Designed for durability and reliability, modern switches often incorporate safety features to prevent overload and short circuits. By providing a simple yet effective means of managing electrical circuits, switches play a crucial role in everyday technology and automation.
