Panel indicators and pilot lights are essential components in modern industry and are widely used in the control system, signal system, electrical instrumentation and other areas of automatic control technology. They are mainly used for indicating and controlling the states or leakage of the equipment in order to ensure the safe and reliable operation. By simply glancing at the panel indicators or pilot lights, the user\'s can quickly acknowledge the status of the controlling system and thus the equipment can be operated and monitored in a safe manner.

19501431 panel indicators and pilot lights mainly consist of light source, base and switch. The light source can be either incandescent or LED lamp. The base has one or two pins on the back, so that it can be connected to the terminals of the control or switch system. A switch is embedded between base and light source. When signal detected, the switch will turn on the light source.

At the same time, the number of pins on the base of the panel indicators and pilot lights also varies. The one-pin panel indicator is connected to the control and monitoring system by only one end. When the control and monitoring system detects a certain signal, it pushes up the pin on the base of the indicator and the indicator will light up, indicating that the signal has been detected. While, the two-pin indicator has two pins, one connected to the control system, the other connected to the power supply, which controls the opening and closing of the electric circuit to achieve the purpose of signaling and controlling.

However, the two-pin indicator has higher requirements for the control system and the electric current needed for the light source is usually more than for the one-pin indicator. It can be used to indicate whether the control system has detected normal or abnormal signal, such as power failure, electrical leakage, overvoltage and current over-range.

19501431 panel indicators and pilot lights also have other features. In the aviation field, aviation indicator lamps are used to indicate the critical signals in the control system and will always be lit when the power is turned on. This is an important signal for the safety of the aircraft. There are also triggering warnings in the engine rooms of nuclear power plants, which will use the color lighting to indicate the working state. The red light is on when the signal is abnormal, and the white light is on when there is no problem.

In addition, panel indicators and pilot lights also have the characteristics of wide voltage range, long service life and fast response time. Most of them are usually made of high temperature resistant and flame retardant plastic or steel materials, which are very safe and reliable.

In conclusion,19501431 panel indicators and pilot lights are very important components in modern industry because of their wide application field and working principles. With their help, the working state of the control system can be easily monitored, which helps to ensure the secure and efficient operation of the system.
