Automotive Relay Market Overview
The Global Automotive Relay Market is experiencing steady growth, driven by increasing demand for advanced vehicle electrical systems and safety technologies. Valued at USD 17.36 billion in 2023, the market is projected to reach USD 24.72 billion by 2030, growing at a CAGR of 5.18% during 2024–2030.
Automotive relays play a crucial role in vehicle electrical systems by enabling low-current circuits to control high-current circuits safely and efficiently. These devices allow multiple components to be switched simultaneously through a single output, making them essential in applications such as headlights, wipers, car alarms, infotainment systems, anti-lock braking systems (ABS), and electronic control units (ECUs).
Over the past decade, the shift toward electric vehicles (EVs) and hybrid electric vehicles (HEVs), coupled with the rising integration of advanced driver assistance systems (ADAS), has increased the demand for high-performance relays with compact sizes and high contact capabilities. Relays are also vital for vehicle digitalization and connectivity features, such as keyless entry, sunroof control, mirror adjustment, and infotainment operations. Additionally, growing safety regulations and the rising emphasis on reducing road accidents globally are fueling demand for automotive relays in safety-critical applications.
