Automotive Relay Market Report 2026

The automotive relay market size has grown strongly in recent years. It will grow from $18.53 billion in 2025 to $19.9 billion in 2026 at a compound annual growth rate (CAGR) of 7.4%. The growth in the historic period can be attributed to vehicle electrification growth, increasing electronic content per vehicle, demand for circuit protection, automotive production expansion, adoption of body electronics.

The automotive relay market size is expected to see strong growth in the next few years. It will grow to $26.7 billion in 2030 at a compound annual growth rate (CAGR) of 7.6%. The growth in the forecast period can be attributed to increasing ev penetration, demand for high-voltage relays, smart vehicle architecture growth, adoption of solid-state relays, advanced driver assistance integration. Major trends in the forecast period include growth of relay demand in electric vehicles, miniaturization of automotive relays, integration in advanced electronic systems, rising use in safety and comfort features, expansion of solid-state relays.

The growing production of commercial and passenger vehicles is anticipated to drive the growth of the automotive relay market in the future. Passenger vehicles are designed to transport individuals, while commercial vehicles carry a larger number of people for business purposes. This high level of production necessitates a significant number of automotive components, including automotive relays, to be installed in new vehicles, thereby boosting the growth of the automotive relay market. For example, in August 2024, the European Automobile Manufacturers' Association, a Belgium-based organization, reported that new car registrations increased by 3.9% in the first seven months of 2024, surpassing 6.5 million units. The largest markets within the bloc showed positive but modest growth, with Spain (+5.6%), Italy (+5.2%), Germany (+4.3%), and France (+2.2%) all reporting increases. Thus, the rising production of vehicles is fueling the growth of the automotive relay market.

Major companies operating in the automotive relay market are concentrating on the development of innovative products, such as compact high-current relays, to improve power efficiency, reliability, and space utilization in modern vehicles. Compact high-current relays are small electromagnetic or solid-state switching devices designed to handle high electrical loads efficiently while minimizing space requirements in automotive and electronic systems. For instance, in April 2023, Fujitsu, a Japan-based technology company, introduced its 30A automotive relay, the FTR-G3. This relay is the world’s smallest in the 30A class, capable of switching 30A of current within a compact, plastic-sealed package measuring just 6.6 mm × 13.7 mm × 14 mm. Featuring a 30A fuse rating, its space-saving design makes it well suited for applications such as power windows, defoggers, seat heaters, lamps, and wipers. The relay offers a high contact capacity, supporting a minimum of 100,000 operations at 14VDC and 30A, and functions reliably across a wide temperature range of -40°C to 125°C, with a rated power consumption of approximately 640 mW at 20°C.

In November 2023, Hongfa Group, a Chinese firm that specializes in electrical components and systems such as relays, switches, and sensors, acquired HELLA for an undisclosed amount. This acquisition aims to expand its market reach, diversify its product portfolio, and gain access to new technologies. As a result, this move enhances Hongfa Group's position as a leading supplier of electrical components for the automotive industry. HELLA, a German company, is a prominent supplier of lighting systems, electronics, and sensors for the automotive sector.
