905-NWR5H-O

905-NWR5H-O are a type of panel indicator commonly found in electrical and electronic control systems. These devices are used to indicate the status of an electrical circuit by means of a light or LED. The device is a small button type switch that has a LED in the center, surrounded by a metal bezel with a lens. The LED is powered by an external voltage typically provided by the equipment powering the circuit. The device has two wires that connect to the LED, and a push button on one side of the switch that is used to activate the LED.

The working principle of 905-NWR5H-O is based on the use of a circuit consisting of two relays. When the switch is pushed, one of the relays closes, causing an electrical current to flow through the LED. This activates the LED, causing it to illuminate and indicate the status of the circuit. The device is normally off unless explicitly activated, meaning that the LED will only remain lit if the circuit is “on.”

905-NWR5H-O are extremely useful in control systems, where the status of the circuit needs to be monitored and quickly changeable. They’re also useful in identifying and addressing issue quickly, since the LED is always visible. These devices are often used in conjunction with fuses, circuit breakers, and other safety devices as they allow for quick verification of the status of the circuit.

Overall, 905-NWR5H-O devices are an essential part of electrical and electronic control systems, where their use in providing a visual indication of the status of the circuit makes them invaluable. They’re also easy to install and use, making them a great choice for a wide range of applications.
