Tips: the function of the emergency push button switch
The emergency stop button is a measure that people can quickly press this button to achieve protection when an emergency occurs.
In various factories, eye-catching red buttons can be seen on some large and medium-sized machinery and equipment or electrical appliances. The standard ones should have red fonts that have the same meaning as "emergency stop". Such buttons can be collectively referred to as emergency stop buttons. This button can be directly pressed down to quickly stop the whole equipment or release some transmission parts. If you want to start the device again, you must release this button, that is, you only need to turn it clockwise about 45° and then release it, and the pressed part will bounce.
In industrial safety, it is required that all machines whose transmission parts directly or indirectly cause harm to the human body under abnormal conditions must be protected. The emergency stop button is one of them. Therefore, the emergency stop button must be added when designing some machines with transmission parts. And it should be set on the surface of the machine that can be easily pressed by personnel, and there should be no obstructions.
