Automotive Relay Market Outlook:
Automotive Relay Market size was valued at USD 15.99 billion in 2025 and is expected to reach USD 28.91 billion by 2035, registering around 6.1% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of automotive relay is evaluated at USD 16.87 billion.
The growing popularity of electric and hybrid vehicles is driving a substantial expansion in the automotive relay market. Automotive relays act as switches for power supply and control signals and are essential to the functioning of electrical systems in automobiles. Furthermore, the market for automotive relays is expanding due to the increased complexity of electrical systems in automobiles. According to a report by International Energy Agency (IEA) around 14 million new electric vehicles were registered globally in 2023, bringing the total number of vehicles on the road to 40 million.
Throughout the projected period, it is expected that the average number of relays fitted per automobile will climb due to the rising utilization of complex electronic equipment and the increased attention on safety and security. The switching of auxiliary devices for safety, security, communications, and entertainment requires additional relays along with the conventional ones used in powertrain systems. Increased developments in PCB relays to lower overall vehicle weight for better fuel economy are predicted to spur market expansion throughout the projected period.
