The 461-NWB28H-NWO series consists of visual indicators designed for panel mounting in the form of a bezel. They feature a low profile, 1/2” diameter switch actuator, a distinctive yellow “OFF” marking, an approximate 2:1 ratio between the long and short actuator lengths, and a panel cutout size of a standard 1/4”. They are available with a variety of lens colors, a choice of either voltage or current ratings, type NEMA 1, 3, 4, and 4X ratings, and a choice of special mounting hardware for automated assembly.

The 461-NWB28H-NWO series is comprised of two distinct types: pilot lights and panel indicators. Pilot lights display the status of the switch position or system condition; the pole position is on/off, open/closed, or up/down. Pilot lights are available in red, green, yellow, blue, and amber lens colors. Panel indicators serve the same purpose as pilot lights, but without the additional status information provided by the pole position. Panel indicators are available in green and yellow lens colors.

The working principle of the 461-NWB28H-NWO series is fairly simple. When the switch is in the “OFF” position, the lens of the indicator is in the “OFF” state. When the switch is in the “ON” position, the lens of the indicator is lit, providing a visual indication of the switch’s status. The voltage/current rating of the indicator is determined by the power source connected to the switch actuator. The power source must be the same voltage/current rating as the 461-NWB28H-NWO series.

The 461-NWB28H-NWO series utilizes a standard mounting bracket for panel installation, allowing for easy assembly. The mounting bracket is designed to accommodate both the indicator and the switch actuator. Additionally, NEMA 1, 3, 4, and 4X rated enclosures with a range of mounting hardware can be acquired for specialized installations. The 461-NWB28H-NWO series includes an LED backlight for further aiding switch identification.

The 461-NWB28H-NWO series is an ideal solution for applications that require visual indication of switch position. They are designed for years of trouble-free operations in harsh environments, such as the machines in industrial and manufacturing plants. With a variety of lens colors and type ratings, they are suitable for many applications where the status of a switch needs to be visible. Their reliable performance and low profile appearance make them suitable for any panel installation.
