The rapid development of computer technology, modern communication technology, optoelectronic technology and space technology has put forward new requirements for relay technology. The development of new technology and new technology will undoubtedly promote the development of relay technology.
　　
The rapid development of microelectronics technology and ultra-large-scale IC has also put forward new requirements for relays. The first is miniaturization and sheeting. For example, the IC packaged military TO-5 (8.5×8.5×7.0mm) relay has high vibration resistance and can make the equipment more reliable; the second is the combination and multi-function, which can be compatible with IC and can be built-in Amplifiers require sensitivity to be increased to the microwatt level; the third is full solidification. The solid state magnetic latching relay has high sensitivity and can prevent electromagnetic interference and radio frequency interference.
　　
The popularity of computer technology has significantly increased the demand for relays for microcomputers, and relays with microprocessors will develop rapidly. In the early 1980s, digital time relays produced in the United States could be controlled by instructions. The combination of relays and microprocessors developed to form a compact and complete control system. Computer-controlled industrial robots are currently growing at an annual rate of 3.5%. Now, the computer-controlled production system can produce a variety of low-cost relays on one production line, and can automatically complete a variety of operations and testing tasks.
　　
The development of communication technology has far-reaching significance to the development of relays. On the one hand, due to the rapid development of communication technology, the application of the entire relay has increased. On the other hand, since optical fibers will be the aorta of the future information society transmission, new types of relays such as optical fiber relays and reed optical fiber switches will appear under the impetus of optical fiber communications, optical sensing, optical computers, and optical information processing technologies.
　　
Optoelectronics technology will greatly promote the relay technology. In order to realize the reliable operation of optical computers, bistable relays have been trial-produced.
