Allen-Bradley 800H-QRB24G Momentary Push Button

Allen-Bradley 800H-QRB24G is a 30 mm green, momentary push button with an extended head designed for panel mounting in industrial control systems. This illuminated 800H device operates at 24 V AC/DC and uses standard contacts: 1 normally open (NO) and 1 normally closed (NC), making it suitable for simple start/stop or input signaling in automation circuits. The extended head is without a guard, and terminals are unguarded, supporting compact panel layouts while maintaining rugged field reliability. As part of the 800H family, it fits the common 30 mm push-button footprint and is compatible with standard 30 mm operator configurations for easy replacement in control stations. The unit uses incandescent illumination to indicate status and is color-coded green to signal go or run conditions in control logic. Typical applications include machine control panels, conveyors, and processing lines where a momentary input is required to trigger a control action without latching.
