Panel Indicators, Pilot Lights

250755833500 Application Field and Working Principle.

The 2507558335 Panel Indicators, Pilot Lights belong to the 2507 family of indicators, also referred to as pilot lights. This type of indicator is typically used to indicate the condition of a system, such as whether it is operating, in an alarm state, in an active mode, or in a standby mode. It is also used to indicate the level of process control within a system.

Panel indicators are typically mounted directly on the face of a panel, or directly onto a terminal block, in order to be visible from the front of the control panel. Pilot lights are simply miniature lights mounted in line with panel indicators, which illuminate to indicate a change in system condition. Both panel indicators and pilot lights typically feature a plastic snap-in base with a male thread for easy installation.

The working principle behind panel indicators and pilot lights is quite simple. There is a small LED bulb sealed in an epoxy casing, typically inside the bottom of the switch, which glows whenever a certain voltage is applied. When power is applied, an electric current flows through the LED, causing it to emit a visible light. The LED will only light up when a certain voltage threshold is reached.

The common voltage ratings for panel indicators and pilot lights range from 12V to 120V DC. A wide range of sizes are available as well, ranging from 0.25" to 1.5" in diameter. Most panel indicators and pilot lights come with a signal switch, which can be used to activate the device. The switch usually has two positions:On and Off.

Panel indicators and pilot lights can be used in a variety of applications, ranging from residential to commercial and industrial. They are often used in control systems, fire alarms, industrial machinery, and security systems. They can also be used to indicate warnings, system status, out of range conditions, and so on.

Panel indicators and pilot lights are typically affordable and easy to install. They are an essential component in any control application, as they are used to quickly and easily alert operators to changes or faults in a system. With their small size, they can be placed anywhere inside of an enclosure, making them invaluable for alerting operators to potential system errors.
