Allen-Bradley 800MR-PT16 Push Button Switches

Allen-Bradley 800MR-PT16 is a 22.5 mm round, illuminated pushbutton switch with a red indicator and a Push-to-Test function, designed for panel mounting in 120 VAC control circuits. This 800MR member uses stab-terminal connections for easy wiring and is built for use in standard industrial control panels. The red variant (PT16R) provides a bright visual cue when the button is energized or active, making it well suited for signaling roles in automation equipment. The unit is intended for 120 VAC operation, aligning with common Rockwell Automation pilot-light configurations and compatible with other 800MR 22.5 mm pushbuttons and accessories in the same family. Typical applications include panel indicators and control station interfaces where a clear, quickly identifiable input is needed, such as machine start/stop interfaces, process signaling, or fault indication in manufacturing lines. With its compact 22.5 mm footprint, it fits standard cutouts for easy replacement in existing installations, and the PT16 variant integrates with a family of 800MR components that share mounting dimensions and terminal styles.
