How are relays labeled?
Although most relays are labeled at the bottom, you can always find the 30 pin set perpendicular to pins 87 and 87a for easy identification to the power source. Realizing that 85 and 86 are the coil pins, these pins will be transferring the current through the coil.

What is a 12V relay?
12V DC relay switches are the best solution for full voltage applications, as they allow a low current flow circuit to control a high current flow circuit, like a vehicle’s horn, headlights, auxiliary lamps, fan motors, blower motors and countless pieces of equipment existing on vehicles today.
How a relay works 12V?
Relays install between the power source and the electrical accessory requiring on/off power. When the relay is energized, the high current to operate the accessory flows from the power source, through the relay, and directly to the part.
What are the 2 circuits of a relay called?
Relays involve two circuits: the energizing circuit and the contact circuit. The coil is on the energizing side; and the relays contacts are on the contact side. When a relays coil is energized, current flow through the coil creates a magnetic field.
What is the symbol for a relay?
