Panel indicators, is a kind of visual data indicator used to indicate the running state of the equipment, its operating principle is generally divided into three categories: electrical, optical and mechanical. NL579C3G is a kind of electrical panel indicator. This indicator mainly consists of an illuminated spring link, a current transformer, an insulation copper plate, and a contact switch.

The working principle of NL579C3G is mainly divided into two stages. First, the voltage of one end of the insulated copper plate is connected to the power supply, the current is passed through the transformer, and the current value is then converted into the power value.

Second, the current passes through the illuminated spring link, in which a part of the current is used to heat up the spring, due to the warming heat production, the contact switch of the spring will touch the closed circuit. By detecting the current change of the illuminated spring link, the working state of the equipment can be related. Therefore, the working state of the equipment can be effectively monitored, ensuring the normal operation of the equipment.

In the actual application, the NL579C3G indicator is placed on the panel. In this way, without the need to open the cabinet, one can directly monitor and observe the running state of the equipment. The NL579C3G indicator has the following features:

• With wide voltage and power range;
• Low power consumption, use for a longer time;
• The contact switch can monitor the contact failure state.

In general, NL579C3G is an electrical panel indicator, which is widely used for monitoring the state of electrical appliances. It is relatively easy to use, and is widely used in the field of industry, such as the industrial control, communication, home appliances, and other applications.
