Automotive relays

Automotive relays are electrical switches used in vehicles to control high-power devices, like headlights or motors, using a low-power signal. When electricity flows through the relay's coil, it creates a magnetic field that closes or opens contacts, allowing or stopping current to larger components. This helps protect delicate components from high voltage and reduces the amount of current needed to activate devices, enabling more efficient use of the vehicle's electrical system. Essentially, relays act as intermediaries that help manage and direct electrical power in a safe and effective way.
