Horns are a mandatory part of the safety equipment of a vehicle. A particularly perceptible sound is necessary in order to be able to warn other road users optimally in dangerous situations. Our signal horns offer you a high level of functional reliability. Design and function: The driver presses the “horn” on the steering wheel. The signal is sent via a relay, thus activating the electromagnet. The diaphragm of the horn is now attracted by the magnet, separating the Minus Pole from the battery so that the magnet loses its power – consequently, the diaphragm returns back to its rest position. However, this will reconnect the Minus pole, so this process will be repeated as long as the horn is pressed. When the horn is pressed, the vibrations are very fast and so produce the loud sound.
