A "Stop Button" is a control mechanism designed to halt the operation of a machine or system. It is commonly found in various devices, such as elevators, industrial machinery, and computers. The primary purpose of a stop button is to ensure safety by allowing users to quickly and easily stop operations in case of an emergency or malfunction. In many cases, the stop button is brightly colored, often red, to make it easily identifiable. When pressed, it interrupts the power supply or halts the process, preventing potential accidents or damage. This feature is crucial in environments where quick responses are necessary, such as in factories or during emergency drills.
