What does a horn relay mean?
1 Answers
horn is the relay for the car horn. Here is a detailed introduction to the car horn relay: 1. Working principle: Most car horns are controlled by electromagnetic relays. The working principle of an electromagnetic relay is that when the relay's power is energized through the button on the steering wheel, it controls the circuit end through the coil, simultaneously driving the movable contact of the electromagnetic relay to close with the stationary contact. This causes the controlled circuit to conduct, and the horn connected to the terminal will start functioning. 2. Method for selecting a relay: Observe the coil voltage on the car. Most car circuits use 12v or 24v.
