Allen-Bradley 800MR-QB24S is an illuminated pushbutton in Rockwell Automation's 800MR family, designed for general signaling on industrial control panels. The QB24 variant engages with a 24-volt supply to power the indicator lamp, enabling visible status indication in electrical circuits. Used in machine control and automation panels, it pairs with other 800MR components to provide a simple, reliable human-machine interface input and control signaling for PLCs and relay logic.
