By household electrical appliances, communications and automotive electronics demand in areas such as the promotion, control relays this year's market was growing. According to Chinese control relay Industry Association data show that in 2003 mainland China relay industry output of about 1.5 billion of the world's supply of the relay around 20 percent. 04 will also maintain more than 10 percent of the growth momentum. At present, China's domestic relay manufacturers about the number around 300, mainly concentrated in Jiangsu, Zhejiang, Guangdong and Fujian and other places, mainly small and medium-sized enterprises to scale, only a dozen of the larger companies.

In China, power relay in the overall relay the largest share of output. As steady growth in product sales, higher profits, most companies are focused on the production of power on the relay. 2003 China Power Relay output reached 1.08 billion on sales of about 96 million U.S. dollars. At the same time electromechanical relays due to household appliances, industrial automation and control and automotive electronics fields of demand-driven, there's rapid growth.

In the meantime, many enterprises are in the relay to seize the opportunity, have plans to increase production. But suppliers are expanding production at the same time, but also continuously improve the level of automation and production of new research and development. At present, the power relay to the current portfolio and the development of type, rated at a higher power relay products supplier is the focus of product development.

Automotive relay the rapid growth of R & D more compact products to the market

The rapid growth of the automotive market, led the market on the motor areas of growth in demand for machinery of the relay. Hongyuan Industry Co., who pointed out that the relevant market for automotive relays this year, the growth in demand by 80 percent, driven relay overall production increased by 50%. He said: "I expect the next 12 months, demand will grow 80 percent." Towards the Asian output in the past 12 months also increased by 10 percent, the growth in automotive applications particularly significant. Yu-heng of the Electrical and Mechanical Services is also concerned that the growth momentum of industrial relay from automotive applications. At the same time the car relay product development trend is mainly concentrated in improving the accuracy, narrow shape size, reduce weight, enhance operational stability and long life, and so on. According to the survey, Hongyuan Industry Co., introduced the car relays only the smallest Dimensions 14 ¡Á 5mm. Yu-heng of the Electrical and Mechanical launched YH507 telecommunications electromechanical relays the size of 12.5 ¡Á 7.5 ¡Á 10mm, weighs 2.2 g. Asian products into the size of 10 ¡Á 11mm, height of 12.5 mm.
