Amplification of Control Signals:
Relays amplify low-current signals, typically from a switch or electronic control module, to control high-current devices. This allows for the use of smaller and less expensive switches in the vehicle's interior while still handling the power requirements of various components.
Switching High-Current Loads:
- The main purpose of a relay is to switch high-current loads on and off. This includes components such as headlights, cooling fans, power windows and other devices that require a significant amount of electrical power.
Versatility in Applications:
- Multi-use relays are designed to be versatile and can be employed in various applications within a vehicle and compatibility with relay sockets make them easy to install and replace as needed.
Efficient Power Distribution:
By using relays, a vehicle's electrical system can efficiently distribute power to different components without the need for heavy-gauge wiring throughout the entire vehicle.
