Emergency stop switches are used in many places in our lives, but many of them do not understand the steps to use them. According to the understanding of the emergency stop switch is actually a master command to control the type of electrical appliances, there is a physical knowledge. To know how to use the emergency stop switch, not only to know what is the emergency stop switch, but also to read the contents of the relevant manual carefully. Next, we will specifically explain the features of the emergency stop switch , as well as the relevant content of the emergency stop switch use and classification. 
Emergency stop switch features
1. For example, emergency stop switches are installed on some machines. When the machine fails or there is a danger, we can cut off the power supply through the installed emergency stop switch and stop the operation of the equipment to achieve the protection of personal and equipment safety. . The emergency stop switch is usually a manually controlled push switch, and the control circuit of the series access device is used to directly disconnect the power of the control circuit in case of an emergency so as to quickly stop the device from abnormal operation. Good sealing performance can be used in the harsh environment of gas, coal dust, smoke, moisture, etc. Both ends are equipped with plastic coated drawstrings. After the sensor operates, the locking release lever springs up and is reset manually. The switch has four outlet nozzles, two of which are the inlet and outlet of the main cable, and the other two are respectively connected to sensors or annunciators. 
2, IP65 is a protection level, in the thunderstorm weather we do not have to worry about it being rain wet, generally more suitable for outdoor or indoor, then the modular structure design, various functional modules can be flexibly combined, use Convenience. The contact module can be superimposed. The single layer can hold 3 contact modules. The double layer can hold 6 contact modules. The contacts are made of silver cadmium oxide (AgCdO15) material. They have strong connection and breaking ability and long service life. The indicator with light button adopts LED lamp, which has high brightness, long service life and low power consumption. The wiring screw has a spring ring, which ensures reliable connection and prevents loosening. The knob switch and the key knob switch have the function of preventing the follow-up, so that the phenomenon that the body rotates with the handle during use may be avoided. 
Emergency stop switch using attention and classification
1, using attention
Before we use the emergency stop switch, we need to make a relative understanding of some matters, so that it will be more practicable to use it. In industrial safety, where there are some transmission parts, direct and indirect abnormalities may occur. Machines that cause injury to the human body must all be protected. The emergency stop button is one of them. Therefore, when designing some machines with transmission parts, the function of emergency stop button must be added, and it should be set on the surface of the machine that can be conveniently pressed by personnel, and there should not be any obstruction. Emergency stop button switch, just press directly down, you can quickly make the entire device immediately stop or release some transmission parts. To activate the device again, this button must be released. That is, it must be rotated about 45° in the clockwise direction and then released. The pressed portion will pop up. 
2, classification
There are two types of emergency stop switches in terms of use, one is manual, and the other is manual. First, the emergency stop switch will access the circuit, and the bottom two parts correspond to the control loop. Then the 380V connection method is that the power supply A is connected to any contact of the emergency stop → emergency stop another point is connected to a certain point of the control circuit → the other point of the control circuit is connected to the power phase B. If it can't work, the emergency stop switch's lead shouldn't move, and swap the two points of the control circuit. Some contactors have different directions. The 220V connection method is the FireWire connection emergency stop any contact → emergency stop another point to the control circuit point → the other point of the control loop to connect the zero line.
The above characteristics on the emergency stop switch, emergency stop switch and associated content Note the use and classification introduced here, I hope these help you.
