BRIEF INFORMATION Super Tone Horn B133
PRODUCT FEATURES
Application
Horns are a mandatory part of the safety equipment of every vehicle. A particularly perceptible signal is necessary so that other road users can be warned effectively in dangerous situations. Our signal horns offer you a high level of functional reliability.
Design and function
Horns are powered by battery current, which is normally controlled by the steering wheel via a control current. This is directed to a relay, which transmits the entire control current so that no voltage drops occur. The control current activates the solenoid in the horn and generates a magnetic field that attracts a metal core (armature) to which the steel diaphragm of the horn is fastened. In an attracted state, the power supply is interrupted, the magnetic field breaks down, the armature and diaphragm move back to the rest position and the power supply is re-established. The process then begins again. This causes an oscillation, which can be heard as a low or high sound.
