Relay market in China is currently in a period of rapid growth, in textile machines, air conditioners, elevators, metallurgy and other industries are widely used. Relay market in China in the past few years maintained a high growth rate. According to estimates, calculated according to the demand of the Chinese market, at least in 10 market saturation and maturity. Therefore, the relay market in China has a broad development space. Judging from the market, our market share of domestic brands in the market, and only 20% to 25%.

Judging from growth within the industry, it has achieved good growth in the first half. Institutes in six months for intensive investigation of the important reasons. Some analysts pointed out that macroeconomic bias since the first half of the vulnerable, though, but the recent disclosures of listed companies in the industry from the semi-annual report, the actual market development boom exceeded market expectations.

Statistics show that in recent years, the relay market has maintained a 12%~15% growth is expected for at least the next 5 years, the relay will remain 10% growth above market demand. After 10 years, relay market becoming saturated.

Of course, as users demand progress and diversification of relay function in continuous improvement and increased integration and systematization of degree have become more sophisticated, and there have been some domain-specific relay. Relay principle is: as long as both ends of the coil and a certain voltage, will certainly current in the coil, resulting in electromagnetic effect, armature will overcome in under the action of electromagnetic forces attract return spring tension towards the core, thus spurring armature moving contact with fixed contact (normally open contact). When the coil is powered off, electromagnetic force has disappeared, armature reaction in the spring to return to the original position, the dynamic contact point with the original static contact (normally closed contact) release. Pull-in, release, so as to achieve the purpose of conduction in the circuit, cutting. For relay "normally open, normally closed" contacts can be distinguished: the relay coil is not energized when static contact point is in a disconnected state, known as the "normally open contact"; static contact is in the on State is called "normally closed contact". Relays generally have two circuits, and high voltage circuit for low voltage control circuits.

Relay industry prospects, China relay industry competition. Due to market highly attractive, not only the market has formed a certain scale, and potential capacity is also very impressive, continues to attract new players in the industry, development of relay technology, the relays in the power, mining, metallurgy, cement, Elevator modernization, transportation and other fields has been unprecedented promotion and application, believe that the relay will be used more and more widely, and market prospects. Relay companies should take "Twelve-Five" East wind of energy saving, better establishing the concept of energy saving. Product energy performance to a higher level, this relay is very favorable for the future development of enterprises.
