The global automotive relay market size was valued at USD 13.53 billion in 2022 and is expected to grow at a compound annual growth rate (CAGR) of 8.1% from 2023 to 2030. Electric automotive parts have diversified over the past decade, leading to an increase in the number of relays used as switching devices and variation in the required features of each relay. The industry is expected to witness steady growth over the forecast period owing to advancements in miniaturization and high contact capability development to address restrictions in mounting space in the Electric Control Unit (ECU) of vehicles.

 

Electric automotive parts have diversified, thereby increasing the number of relays used for switching; different features are required for each relay. Further miniaturization and high contact capability development are needed, especially in the Electric Control Unit (ECU), where there are restrictions in mounting space due to the presence of a cluster of relays. A high degree of reliability in relays is required from a safety point of view. Components equipped with features such as latching, low noise, and ultra-miniaturization have gained prominence owing to the need to provide switching technology for the latest generation of electronic functions in a car.
