Automotive relays are used to control high-power devices in vehicles, such as headlights, fuel pumps, and starter motors, by allowing a low-power signal to switch them on or off.
Automotive relays are specifically designed to withstand the harsh conditions of automotive environments, including temperature fluctuations, vibrations, and exposure to moisture, while standard relays may not have these durability features.
Common types of automotive relays include single pole single throw (SPST), single pole double throw (SPDT), and multi-pole relays, each serving different functions based on the electrical requirements of the vehicle's systems.
