1. For example, if an emergency stop switch is installed on some machines, then when the machine fails or is in danger, we can cut off the power supply and stop the operation of the equipment through the installed emergency stop switch, so as to protect the safety of people and equipment. The emergency stop switch is usually a manually controlled push-button switch, which is connected in series to the control circuit of the equipment, and is used to directly disconnect the power supply of the control circuit in case of emergency, so as to quickly stop the equipment to avoid abnormal operation. The sealing performance is good, and it can be used in harsh environments such as gas, coal dust, smoke, water vapor, etc., and both ends are equipped with plastic-coated pull ropes. After the sensor moves, the locking release lever springs up, and the switch is manually reset, and the switch has 4 outlets, two of which are the introduction and outlet of the main cable, and the other 2 are connected to the sensor or annunciator respectively.
2. IP65 is a protection level, we don't have to worry about it being wet in the rain during thunderstorms, and it is generally more suitable for outdoor or indoor, so the modular structure design, various functional modules can be flexibly combined and easy to use. The contact modules can be stacked, 3 contact modules can be installed in a single layer, and 6 contact modules can be installed in a double layer, and the contacts are made of silver cadmium oxide (AgCdO15) material, which has strong switching and breaking capacity and long life. The indicator light with light button adopts LED light, high brightness, long life, low power consumption, and the wiring screw has a spring coil for reliable connection and prevents loosening. The knob switch and key knob switch have the function of preventing follow-up, which can avoid the phenomenon that the body rotates with the handle during use.
