Q&A about 120 volt indicator light
– What is the role of 120 volt indicator light?
120 volt indicator light is used to display the working status of the electrical appliances on 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. It works. When the electrical appliance stops working, the indicator light goes out, and the indicator light also stops its operation. Of course, there are also two-color indicator light. The basic two-color colors are green and red. When indicator light In the resting state, the color of the indicator light is green. When the indicator light is in the working state, the color of the indicator light is red.
– How does 120 volt indicator light work?
Inside the thermal scintillator are some simple components: 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 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 current can flow in the circuit. At first, the spring steel plate did not 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 bent 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, so the circuit is broken. Then a new cycle began. This cycle occurs once or twice per second.
– How many colors does the 120 volt indicator light have?
Generally speaking, the colors of 120 volt indicator light are red, yellow, blue, green, white and purple, but when you need other special colors, we can customize them for you.
– How many volts does 120 volt indicator light have?
The voltage of indicator light is 3V, 6V, 12V, 24V, 110V, 220V, 380V. When customers need a high-strength voltage of 720V, we can also make them for customers.
– What is the waterproof rating of indicator light?
The default waterproof rating of volt indicator light is IP66, and FILN also has a certificate of waterproof rating. If the customer has requirements for the waterproof level, for example, if the customer requires the waterproof level of the 120 volt indicator light to reach IP67 or IP68, we can also make it. The company also designed a waterproof test bench, using high-strength water pressure and long-term immersion. Volt indicator light. The waterproof rating of 120 volt indicator light is excellent, reaching IP67 waterproof rating.
– What are the certification certificates of the indicator light?
This indicator light has passed American UL certification, EU ROSH certification, and EU CE certification.
