80A relay 12V
The horn relay is the electronic component that is a part the vehicle’s horn circuit.
It serves as the rely that controls power to the vehicle’s horn.
When current is applied to the rely, the horns power circuit is completed, allowing the horn to function and ring.
The horn relay switches a large current to the horns at a signal from the low-current horn button in the steering wheel.
A simple SPST relay will have a constant supply of 12 volts to it, a lead that runs through the harness to the horn, another lead that runs to the horn switch in the wheel, and a ground.
One of the most common situations that require the use of a relay occurs when an application needs to switch from high to low current (or vise versa) within the same circuit.
