What is the principle of automotive relays?

The principle of automotive relays is to use the principle of electromagnetic induction. When direct current passes through the coil, a magnetic field is generated, and the moving iron is attracted to drive the contact spring, causing the static contact to separate and the moving contact to close. When the current of the electromagnetic coil is cut off, the iron core loses its magnetism, and the moving iron core resets under the action of spring force. The moving contact opens and the static contact closes. The contact of the relay coil in the disconnected position when not powered on is a normally open contact, and the contact in the connected position is a normally closed contact. Between a normally open contact and a normally closed contact, there is a moving contact called a transfer contact. In the same relay, it can have one or more normally open contacts, normally closed contacts, and transfer contacts. Generally, there is only one coil in an electromagnetic relay. In order to clearly and simply represent the relay on the circuit, a character symbol is usually used to represent the relay coil and its contacts, and each group of contacts is marked with a corner mark.
