With the development of automotive electronics and electrical products in recent years, automotive relays have also developed by leaps and bounds. The production and sales of automotive relays in the world are gradually increasing.

At present, the sales of automotive relays account for about 20% of the total sales of relays. The automotive industry has become the second largest relay application field after the communications industry.

In 2011, global relay sales were US$4.22 billion, of which automotive relay sales were US$850 million. It is estimated that in 2012 global relay sales will reach US$4.4 billion, of which automotive relay sales will be US$890 million, an increase of 4.71%.

In 2011, the world automobile population will reach 1 billion vehicles, and the annual output will be 75 million. For example, the average amount of relays used in each vehicle will be 20, the average amount of relays used for maintenance of each vehicle will be 10, and the amount of vehicle repair will be maintained. Calculated by 10% of the volume, the world's automotive relay market demand will exceed 2.5 billion in 2012. From this we can see that the development space for automotive relays is very large.
