In this occasion, lets learn about relay which we can found this tool in our electrical's automotive. How a relay works 12v? the relay works only use one circuit to switch on a second circuit.its mean one circuit for double function like the following explanation when power flows through the first circuit, this circuit activated the electromagnet signed by brown color, generating a magnetic field (blue color) and send a contact then activated the second circuit. when the power is switched off, a spring pulls the contact back up to its original position, by this activity can switch the second circuit off again. we hope this explanation is clear about how relay is works.

What is an automotive relay? an automotive relay is an electronically operated switch. as we found relay in our car works to operate switch on and off. trhe shape of relay in automative industry described as small cube with double function which can switch on/off. when you look at relay you will found the number than what the number working for? at center of relay we found the number 87 A this is where the power is go when relay is not hot. than how about another four numbers? all of the number indentification has function for each. like number 85 is used for grounding and number 30 is 12V supply, 86 is trigger wire 12 volt when switched. for the last 87 used for 12 volt output for accessory such as light, horn, etc.

As the fastest growing demand of circuit and wiring diagram for automotive and electronics on internet based on different uses such as electronic hobbyists, students, technicians and engineers than we decided to provide free circuit and wiring diagram base on your needed.

To find circuit and wiring diagram now a day its easy. E-learning through internet as a right place to search an exact circuit and wiring diagram of your choice and it's much fun and knowledgable. On internet you will find thousands of electronic circuit diagrams some are very good designed and some are not. So you have to modify them to make them according to your needs but some circuits are ready to make and require no changes.

There are many categories of circuit and wiring diagrams like automotive, audio circuits, radio & RF circuits, power supply circuits, light circuits, telephone circuits, timer circuits, battery charger circuits etc. There are many types of circuit and wiring diagrams some are very easy to build and some are very complicated, some are so small and some contain huge list of parts.

We provides free best quality and good designed schematic diagrams our diagrams are free to use for all electronic hobbyists, students, technicians and engineers. We also provides a full educational system to students new to electronics. If you are new to electronics you are a student or a electronic hobbyist and want to increase your knowledge in electronics or want to understand electronics in a very easy way so this is the right place for you we provide electronics beginner guide tutorials to easily understand complicated electronic theory. Our mission is to help students and professionals in their field.
