Automotive relays are critical components in vehicle electrical systems, designed to provide reliable switching and circuit control. They consist of three main systems: a magnetic circuit system, a contact system, and a restoration mechanism. The magnetic circuit system includes the iron core, yoke, armature, and coil, while the contact system is composed of static reeds, moving reeds, and contact bases.

Widely used in automotive electronics, these relays ensure efficient operation of high-power circuits, enabling control over headlights, fuel pumps, and other essential systems. Their robust construction ensures durability and reliable performance in demanding vehicle environments.
