240V indicators

What is the role of the 240V LED indicator light?

240V LED indicator light is used to display the electrical appliances’ working status, which is applied to various home appliances or various machines.

The indicator light is usually off. When the machine starts to operate, the lights up and the indicator light also starts.

When the electrical appliance stop working, the indicator light goes out, and the indicator light also stops its operation.

Of course, there are also two-color indicator lights. The basic colors of two-color are green and red.

When the indicator light is in the resting state, the color of the indicator light is green. While the indicator light is in the working state, the color of the indicator light is red.


Application of indicator light

How does the 240 V LED indicator light work?

There are some simple components inside the thermal scintillator: electrical contacts that conduct current to the wires.

A slightly bent spring steel plate is connected to the electrical contact.

The resistance wire is wound on a small spring steel plate. When the thermal scintillator is turned on to operate the machine with the indicator light, the thermal scintillator is connected to the turn signal bulb through the indicator light switch.

In this way, the entire circuit will be connected and the current can flow in the circuit. At first, the spring steel plate didn’t touch the contacts, so only the resistor was energized.

Electric current flows through the resistance wire to heat the small spring steel plate and then transfers the heat to the indicator light. The current at this time is very small, not even enough to make the indicator light emit a faint light.

But in less than a second, the temperature of the small spring steel plate will rise to a temperature high enough to begin to expand and will stretch into a larger curved spring steel plate.

In this way, the best spring steel plate is forced to touch the contact, so that current flows into the signal lamp, and the signal lamp is not blocked by the resistance.

When almost no current flows through the resistor, the spring steel plate will quickly cool down, shrink to its original shape, and leave the contacts, the circuit is broken. Then a new cycle began. This cycle occurs once or twice per second.
