What would be the difference if the turn signal worked silently? This clicking sound Is it a special reason? is there?

Bride, to all these questions Let’s answer.

The turn signal first appeared in 1909, but the clicking sound was not added until the 1930s.

Inventor Joseph Bell patented a small electronic device that conducted electricity to external return signals. It made a “ticking, ticking” sound.. Later, in 1939, this technology was added to cars.

For example, for the first time in history, cars had flashing turn signals, which provided a new layer of safety. Over time, these clicks give signals, It began to take its place in every car.

So what is the source of this noise?

In most cars, the ‘click, click, click’ sound and signals are produced by a thermal flashing light. Located in the instrument panel and contains a bimetallic spring Electric current passes through this device.

When the signal is turned on, it creates a current that passes through the bimetal spring and heats it. Moreover, the two metals occur in the spring heats up at different rates and forces them to bend in a certain way.

This bend completes the circuit, sending current to the external light, turning it on for a moment and making the clicking sound of that area as the metal clicks into place. So the source of this ‘click, click, click’ sound is bimetal spring in cars It is caused by.

In addition, this sound serves to indicate to the driver that the turn signal is active. Many newer cars a fully chip-controlled turn signal system trusts. In other words, they have no moving parts, that is, bimetallic springs.

But they still make the clicking sound. How? All electronic, with a fake voice!
