Panel Indicators, Pilot Lights

Panel indicators and pilot lights are commonly used in electrical circuit diagrams to signify the state of a given electrical output. They have been developed to provide a reliable, clear indication in order to facilitate the monitoring and control of devices or systems.

This type of panel indicator is specifically designed for low current operation such as controlling low voltage or very small current circuits. Its working principle is based on the fact that the magnetic field of the coil can be influenced by the current that passes through it. This coil has a very small core and the wire is wrapped around it. When a charge is applied to the circuit, the current will flow through the coil and create a magnetic field. This field is then used to activate a plunger, which in turn will move the indicator. The indicator will display a green or red light, depending on the output of the circuit.

These panel indicators are most often installed onto circuit boards, either in individual or group form. In a group set-up, they are arranged in a row to indicate the state for multiple inputs. Due to their simplicity, they are widely utilized for indicating the state of switches, relays, contactors, and various electric circuit controls. Depending on the model, the wires of the coil can be connected into the circuit along with the switch or contactor.

This panel indicator is also often used in the constructions of home automation systems. It provides a simple and effective way to give visual cues for the eight states of the automation system. They can be utilized as symbols on manual circuit boards, to detect the presence of current, or as a signaling device for logic circuits. This signal can be used in order to provide feedback to the user, such as when a switch is triggered, or an alarm is triggered.

Due to its simplicity, these panel indicators are quite inexpensive and reliable. They are relatively easy to install and maintain. In most cases, all that is needed is for wires to be connected to the appropriate set of contacts, although some models might require the further installation of relays. Also, since they operate without any moving parts, they are usually well-suited for long-term applications. Overall, these panel indicators and pilot lights provide a visually appealing and simple way to indicate the state of an electrical system.
