Rotary Knob switch can be used to replace traditional resistance potentiometer simulation function of rotating pulse generator, the rotary switch are normally used in the instrument front panel and audio control panel man-machine interface, rotary switch orthogonal optical encoder as pure digital device to replace analog potentiometer, the rotary switch on the appearance similar to traditional or resistive potentiometer, but the internal structure of rotary switch completely and use digital optical technology. Similar to traditional incremental encoder products have two orthogonal output signal channel A and B), can be directly connected with the encoder processing chip.

Rotary switch knob is to control the main contact a switch on and off. The structure of rotary switch has two kinds, which is one unit structure and more than a multipolar structure. Single unit rotary switch in the application of commonly used jointly with rotor potentiometer, while more than a multipolar rotary switch used for switch working state lines.
CNC is the focus of the future development of the industry in the mold industry
At present, numerical control is the focus of industrial development in the industrial field and the inevitable trend of industrial development. With the continuous improvement of technology, CNC technology will gradually become popular in mold machinery and equipment.
The NC generation equipment innovation project is to promote the application of digital control technology in various types of equipment, integrate and innovate a batch of numerical control equipment, and realize the upgrading of equipment performance and function, and then promote the transformation and upgrading of the equipment manufacturing industry. As early as the beginning of 2011, eight academicians put forward proposals for the implementation of the “Digital Generation First Generation Machinery Product Innovation Application Demonstration Projectâ€, which was highly valued by relevant state departments. In the first half of 2012, the “Digital Generation First Generation Machinery Product Innovation Application Demonstration Project†was released and implemented. In this context, the "CNC Generation Equipment Innovation Engineering Action Plan" was released soon. The development of CNC generation equipment manufacturing has been clearly visible. In the past, the importance of numerical control in 2013 has become more and more important. In the future industrial development, CNC machinery is inevitably the most important aspect.
The "Plan" shows that in order to achieve the goal, five major actions will be organized and implemented: CNC technology development and promotion service platform construction, CNC technology development and industrialization, CNC equipment integration innovation, CNC equipment demonstration and promotion, CNC equipment technical specifications and standard system construction. . Among them, PLC, man-machine interface, control software, inverter, servo drive, energy-saving motor and other automation technologies are the key development targets, and will enjoy the policy rain.
Among them, we must first improve the quality and reliability of a wide range of general-purpose programmable controllers, human-machine interface devices, integrated controllers and software packages.
Secondly, it is necessary to strengthen the development of professional application software and hardware combined with the manufacturing process of typical industries to meet the needs of the development of CNC equipment in the industry.
Focus on the development of servo drives and motors required for various CNC devices, such as digital servo control systems, network distributed servo systems and other servo drives, energy-saving motors and variable-frequency motors.
Focus on the development of high-power, high-performance variable frequency speed control system, traction frequency control device and special speed control frequency control device.
Focus on textile machinery, plastics and rubber processing machinery, small and medium-sized machine tools and basic manufacturing equipment, printing machinery, packaging machinery, food processing machinery, pharmaceutical machinery, energy-efficient products, etc., to achieve numerical control integrated development.
The numerical control of equipment has become an important development trend. Industrial developed countries attach great importance to the development of high-tech equipment. After more than a decade of development in China's equipment manufacturing industry, the proportion of CNC equipment in the domestic market has been continuously improved, and has formed a strong innovation capability. A relatively solid foundation. The release and implementation of the Plan will further advance the numerical control of equipment. Luo Baihui said that China's equipment manufacturing can achieve mold manufacturing, metal processing and other typical industries in 2020 equipment numerical control rate reached 70%. The realization of numerical control equipment development and extension services capabilities significantly enhanced, continue to train a large number of can operate on CNC equipment and Maintenance skills. Achieve the wide application of numerical control equipment, increase the production efficiency of key application areas by more than 20%, and reduce energy and resource consumption by more than 30%.
