How Does an Automotive Relay Work?
1 Answers
Automotive relays operate by generating a magnetic field when the coil is energized, which then attracts the iron piece connected to the contact, thereby closing the circuit and protecting it. The wiring of the relay involves connecting the two wires of the coil to positive and negative terminals, with one end connected to a switch and the other wires connected to the electrical device. A relay is an electrical control device that causes a predetermined step change in the controlled quantity within the electrical output circuit when the input quantity changes to meet specified requirements. Relays establish an interactive relationship between the control system and the controlled system. They are commonly used in automated control circuits, functioning as automatic switches that use a small current to control the operation of a larger current.
