Relay Switch Wiring Diagram For Auto Mobile

The real benefit behind a relay is more than automation.

Relay switch wiring diagram for auto mobile. A wiring diagram is a simplified standard photographic representation of an electrical circuit. Understanding how the relay works will help with diagnosis and modifications to vehicle systems. The factory wiring in modern cars is light gauge and is not designed for additional loads. The purpose of a relay is to automate this power to switch electrical circuits on and off at particular times.

A relay can be used to power a new circuit with very little added current draw on the original wiring. 12 volt relay wiring schematic. Every circuit added to a modern car should be run through an automotive relay. What happens inside a relay isn t magic but it is important.

In this condition no collector current flows and the relay coil is de energised because being current devices if no current flows into the base then no current will flow through the relay coil. Using a relay can also shorten the distance. Our wiring tutorial shows you how to wire the most common relays found in automobiles. When the base voltage of the transistor is zero or negative the transistor is cut off and acts as an open switch.
