Relay manufacturer of a lot of, competition is fierce, and the price of raw materials is rising, and it is difficult for price cut way to win the market, so we face a lot of pressure. Lower profits despite the relay, but manufacturer still remains in the industry, because the market demand for relay has been stable, almost all electronic products need it, so the market is still there.


Automobile relay control is widely used in automobile, air conditioning, lighting, security, audio, navigation, airbag and automobile electronic instruments, meters and fault diagnosis system, it is second only to the sensor in the car one ofthe most used car electronic components. At present, some semiconductor devices to replace relay to control the car, relay will gradually lose the market, for this problem, some of the strengths of the relay is irreplaceable semiconductordevices, for example, in North America, Europe and other places, large temperature difference between day and night, semiconductor devices in temperature, electric current may not meet requirements. Moreover, in places where need high power, the advantage of the relay is very obvious. In small home appliance industry, however, there is also a semiconductor device instead of the relay, compared with motor control, this will probably be earlier trend.
