What is the use of automotive relays

Automotive relays are electrical components used in automobiles to control the operation of various electrical devices and systems, such as headlights, wipers, horns, and fuel pumps. They act as switches that allow electrical power to flow to these devices and systems.

The primary function of an automotive relay is to control a high-current circuit with a low-current signal. For example, a small switch or sensor can activate a relay, which then allows a larger electrical current to flow to a particular component. This is useful because it allows the control circuitry of a vehicle to be less complex and less expensive than if it were designed to handle high currents directly.

Additionally, automotive relays can provide isolation between the control circuitry and the high-current circuit, which can improve safety by reducing the risk of electrical shock and damage to sensitive electronic components.

Overall, automotive relays are essential components that help to ensure the safe and reliable operation of the electrical systems in a vehicle.
