The emergency stop button is a button that people can press it to achieve the protective measure when an emergency occurs.
In various factories, the red buttons are visible on some large and medium-sized machines or appliances. Such buttons can be collectively referred to as emergency stop buttons. Only press down this button directly, it can quickly make the entire equipment stop or release some transmission parts; and you must release this button to restart the device.
In industrial safety, it is required that any machine that can directly or indirectly cause injury to the human body in the event of an abnormal situation must be protected. The emergency stop button is one of them. Therefore, when designing some machines with transmission parts, an emergency stop button must be added. And it should be set on the surface of the machine that can be easily pressed by personnel, and there should not be any shields.
