Panel Indicators, Pilot Lights

070131011100 is a component of panel indicator and pilot lights. Panel indicators are electrical signaling devices that are used for displaying states or providing warning alarms. Pilot lights are commonly used in fields, such as factory automation, industrial equipment, and some home appliances to indicate the operating status, fault alarms, and other user status information. Both are essential parts for machine and device indicating the operation.

Applications and Working Principle

Panel indicators and pilot light are extensively used in industries, from warning signals to text information. The manly applications of panel indicators of pilot lights include industrial equipment, automation controls, and home applications.

The common construction of a panel indicator or pilot light consists of a light source, a base, and an actuator. The base works as a socket for mount the component. It can be either tube type or button type, and the most common types are either metal shell or resin shell. The actuator is the so-called switch that allows the light source to activate or deactivate the light. The light source can be LED type, neon type, and incandescent lamp type. The contacts of the actuator can be either Double-Break (DB) type or Single-Break (SB) type. The differences of LED and neon types are that LED can provide various colors, and the neon type is suitable for high-voltage applications.

Regarding to the working principle, when the actuator is activated, the electrical circuit is closed, which ultimately causes the light source to illuminate. For deactivation, the circuit is opened thereby turning off the light. If the actuator is Single-Break (SB) type, after the circuit is closed and the light is turned on, the circuit will remain closed even if the actuator is removed. On the contrary, if the actuator is Double-Break (DB) type, once the actuator is removed the light will be automatically turned off.

Conclusion

To sum up, panel indicators and pilot lights (070131011100) are of great use in the industrial and home automation. They are featured with the small size, wide range of operating voltage, and a variety of shapes and colors. The common construction of a panel indicator or pilot light serves as a medium to achieve the illumination. By merely operating the actuator, the light source can be effectively activated or deactivated.
