How does an automotive relay work. In this relay when a current flows through the coil it turns it into an electromagnet. Just an idea on how to understand the automotive relay thanks for watching. This is a relay from an electronic hot water immersion heater programmer. Relays are found hidden in all sorts of devices. Relays are switches controlled by electrical power like another switch computer or control module. The magnet pushes a switch to the left forcing the spring contacts together and completing the circuit theyre attached to.
A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts. In fact some of the first computers ever built used relays to implement boolean gates. How does a relay work spdt dpdt spst automotive relay duration. Understanding how the relay works will help with diagnosis and modifications to vehicle systems. An explanation of automotive electrical relays and how they work using a small current to switch a larger load without running heavy cables to heavy duty switches on your dash board. What happens inside a relay isnt magic but it is important.
The automotive relay explained. Adding a buzzer that warns when youve left your headlights on this circuit is designed to alert you that youve left. The purpose of an automotive relay is to automate this power to switch electrical circuits on and off at particular times. In this article we will look at how relays work and a few of their applications. Adding a hidden switch that must be pressed. Adding driving lights that come on with the headlight main beam this simple circuit uses the power feed to the.
This application comes into play whereby an in line switch does not have the capacity to handle the current required to switch a high current electrical system.
