Allen-Bradley 800T-QB10 Illuminated Push Button

The Allen-Bradley 800T-QB10R is a 30 mm momentary illuminated push button with an extended head without guard, designed for panel mounting in industrial control stations. This red-lens 800T-QB10R variant is part of the 800T family and ships with a standard 800T-XA contact block (1 normally open, 1 normally closed), enabling straightforward start/stop signaling circuits. The unit is described as illuminated, providing visible status indication when pressed, and is suitable for use in machine control panels and process signaling where a clear pilot light is helpful. The 800T-QB10R uses the extended head without guard configuration and is designed for 30 mm panel cutouts, with compatibility to a range of 800T accessories for expanded functionality. In typical industrial automation applications, it serves as a user input device on control panels, signaling operators and system logic through its red indicator and momentary action.
