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.

The average number of relays installed per vehicle is expected to increase over the forecast period due to the growing adoption of sophisticated electronic equipment and increased emphasis on safety and security. Switching supplementary devices required for safety, security, communications, and infotainment requires additional relays apart from those used in powertrain systems. Increased developments in PCB relays to decrease the overall vehicular weight for increasing fuel efficiency are expected to drive market growth over the forecast period.

With the automotive industry’s transition from hardware to software-oriented vehicles, the average number of software and electronics per vehicle is rising rapidly. New features are integrated into vehicles using electronic devices with various application areas, such as safety management, powertrain, comfort, and infotainment, which employ automotive relays. This is expected to boost the demand in the market during the forecast period.

Passenger safety is another important factor in driving the adoption of automated automobile systems. Vehicle safety features have significantly reduced road accidents and fatalities over the last few decades. Also, the automotive industry is working to transform consumers’ driving experience. Smarter cars capable of performing self-diagnosis are gaining popularity and are anticipated to augment the market’s growth during the forecast period.

The lack of standardization and highly competitive players in relay manufacturing hinders the growth of the global market. During the operation of an automotive relay, large amounts of heat are generated, and other factors, such as durability limitations and switching noise, are expected to hamper the market growth.

The growing demand for hybrid and electric vehicles with advanced, lightweight, and high-performance relays is compelling manufacturers to invest in solid-state relays rather than traditional large electromechanical relays. Thus, this is anticipated to create an opportunity for the market to grow.
