Automotive Relays Are Electrically Operated Switches

Automotive Relays are electrically operated switches used for automotive applications.

Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.

A relay is a system used to separate or alter the state of an electrical circuit from one state to the next. Over the past decade, electric automotive parts have diversified, leading to an increase in the number of relays used as switching devices, as well as differences in the characteristics needed for each relay. The industry is expected to see steady growth over the forecast period due to advances in miniaturization and development of high contact capabilities to overcome increasing space constraints in the Electric Control Unit (ECU) of vehicles.

As a high tech industry, the manufacturing technology of automotive relay is mature but only these international giants can supply the high-end products with excellent performance. There is still a core technical barrier.
Today, the price of automotive relay is lower than past years. The reason for this downward trend of price is the development of technology and the price fluctuations of raw materials. In future, the price would go down continuously and slowly.
