Understanding how the relay works will help with diagnosis and modifications to vehicle systems. The purpose of an automotive relay is to automate this power to switch electrical circuits on and off at particular times.
Relay Wikipedia
How does an automotive relay work. In this article we will look at how relays work and a few of their applications. A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts. Relays are found hidden in all sorts of devices. The magnet pushes a switch to the left forcing the spring contacts together and completing the circuit theyre attached to. This is a relay from an electronic hot water immersion heater programmer. 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.
Just an idea on how to understand the automotive relay thanks for watching. Adding a buzzer that warns when youve left your headlights on this circuit is designed to alert you that youve left. When you need it and why diy duration. How does a relay work spdt dpdt spst automotive relay duration. Adding a hidden switch that must be pressed. In fact some of the first computers ever built used relays to implement boolean gates.
What happens inside a relay isnt magic but it is important. Relays are switches controlled by electrical power like another switch computer or control module. The automotive relay explained. 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. The most common application of automotive relays is to switch a high current circuit using a low current circuit. In this relay when a current flows through the coil it turns it into an electromagnet.
Adding driving lights that come on with the headlight main beam this simple circuit uses the power feed to the.
