Panel Indicators, Pilot Lights

Panel indicators are used to indicate the presence or absence of an electrical potential, thus informing the user if current is being fed through the circuit. They are usually placed in control panels, giving the user a visual cue to the status of the circuit. Panel indicators are usually designed to indicate a specific voltage or frequency.Pilot lights are type of panel indicator used to confirm that electrical equipment is operating normally. Pilot lights provide visual feedback to verify that signs of operation, such as an electrical current, are present in a circuit. Pilot lights come in various sizes and shapes and provide similar functionality to other panel indicator lamps such as LEDs or bi-color LEDs.The working principle of a common panel indicator is based on the difference between the varying current values. The indicator changes color depending on the signal that is captured in the circuit. A current of over 12 volts typically triggers red LED while a current between 9 and 12 volts turns the indicator orange. A current between 6 and 9 volts will turn the LED yellow. Lastly, a current battery below 6 volts will generally cause the indicator to flash green.Panel indicators are used in a wide variety of electronic equipment, including medical devices, laboratory instruments, and various kinds of equipment. In addition, they are also present in consumer products such as refrigerators, washing machines, air conditioners, TVs, and many more. Panel indicators generally serve to provide the user visual feedback about the equipment’s status.The working principle of a pilot light is the same as that of a common panel indicator. A pilot light may be installed in the form of a mechanical switch or switch cover, typically located in the same panel as the main power switch. This way, the user can verify that the circuit is not disturbed and the equipment is operating normally.Panel indicators and pilot lights are very useful for users to quickly determine the status of an electrical circuit. Despite the increased use of digital display panels, these two devices remain very useful in providing a visual cue to the user about the status of an electrical circuit.
