What is Emergency Stop Switch
The emergency stop button can also be called “emergency stop button”, which is referred to as the emergency stop button in the industry. As the name suggests, the emergency stop button is a measure that people can quickly press this button to achieve protection in case of emergency.
In various factories, eye-catching red buttons can be seen on some large and medium-sized machinery and equipment or electrical appliances. The standard should have red font with the same meaning as “emergency stop”. Such buttons can be collectively referred to as emergency stop buttons. This button only needs to be pressed down directly. You can quickly stop or release some transmission parts of the whole equipment immediately. To start the device again, you must release this button, that is, just rotate it clockwise by about 45 ° and release it, and the pressed part will pop up. That’s “release”.
In industrial safety, it is required that all machines whose transmission parts will directly or indirectly harm human body under abnormal conditions must be protected, and the emergency stop button is one of them. Therefore, the function of emergency stop button must be added when designing some machines with transmission parts. Moreover, it shall be set on the surface of the machine that can be easily pressed by personnel, and there shall be no shelter

Installation,removal method for E-Stop Switches
Insert the operating head into the mounting hole from the front of the panel, screw it into the middle seat at the back of the panel, and then tighten the set screws at both ends evenly (don’t use too much force, the maximum torque is 25n-cm). If the panel is plastic and other non-metal, it can be installed after a mounting plate is placed on the back of the panel. If the diameter of the mounting hole is 25mm, it can be placed on the back of the panel φ Install after the mounting plate of 25.
Type a button, the switching element can be installed together with the middle seat For type B button, the switching element shall be removed first, and then the middle seat shall be installed.
Note: if the button is found stuck after installation, adjust the two set screws of the middle seat to keep the same tightness, and then it can be removed.
The switching element can be directly fastened, and the symbol piece of the head can be directly installed at the front (generally installed at the factory)
Note: after installation, check whether the buckle of the switching element is fully buckled.
Remove the switching element or voltage reducer: lift the buckle of the latch installation system with a screwdriver to easily remove the tightly installed components at will.
Working principle of emergency stop button
(1) In terms of action time, the time from closing to opening of normally closed contact is much shorter than that from natural state to closing of normally open contact. Maybe you have to say, how much less? It doesn’t matter in such a short time. But I want to say that this is particularly important when there is a danger and an emergency stop is required. At this time, the shortest time, even milliseconds or even microseconds, is also very important. You know, the accident happened in a very short time. You can think about it. In such a short time, you may not stop the machine or disconnect the switch by using the normally open contact, resulting in major machine damage or personal casualties. But using the normally closed contact, it is possible to stop the machine or make people get an electric shock for a shorter time to avoid all this.
(2) From the button mechanism, we know that the emergency stop button, whether normally closed or normally open, will bounce up again when it is not pressed in place (pressed to the end), so as to invalidate the action. When using the normally open contact, when the emergency stop button is not pressed in place, the emergency stop does not play any role (because the normally open contact is not closed); When using normally closed contact, it is different. No matter whether the emergency stop button is pressed in place or not, the emergency stop works only after the contact acts.
(3) From its control circuit, needless to say, the most basic function of the emergency stop button is to stop in an emergency to avoid mechanical accidents or personal accidents. However, due to the long-time operation of the machine, the line, especially the emergency stop line, may cause fault and open circuit. At this time, if the emergency stop button uses the normally open contact, the line fault of the emergency stop part will not be found. If it is found again when the emergency stop button is used, it will be too late. When the normally closed contact is used, when the line of the emergency stop part fails, the machine will stop at most, and the loss will be relatively small. Based on the above reasons, when designing the electrical control system, it is better to use the normally closed contact for the emergency stop button.
