Automotive relays are made to meet the high standards of the automotive industry, including durability, heat resistance, and reliability, given the harsh conditions vehicles are exposed to, such as extreme temperatures, vibrations, and moisture. Manufacturers often produce different types of automotive relays, including:

Standard relays: Basic relays used for simple on/off switching applications. Micro relays: Smaller relays designed for compact spaces and light-duty applications. Automotive high-power relays: Used for controlling higher-power systems, such as motors or lighting systems. Specialty relays: Relays designed for unique automotive applications, such as those for electric vehicles or hybrid vehicles. Some well-known automotive relay manufacturers include companies like Omron, Tyco Electronics, Schneider Electric, and Panasonic. These companies offer a wide range of relays that comply with automotive industry standards, including ISO 9001 and IATF 16949 certifications.
