Allen-Bradley 800MR-QA24 Flush Head Push Button is a momentary-contact, illuminated control button designed for panel mounting in industrial equipment. It is a full-voltage 24 V AC/DC unit with incandescent illumination; the flush-head assembly ships with no lens and no contact cartridge, and uses stab terminals for wiring. This 800MR push button is intended to be paired with compatible 800MR contact blocks to configure either normally open or normally closed circuits. The flush-head style yields a low-profile operator interface suitable for dense control panels, and it’s commonly used for start/stop and other operator inputs in automated machinery.
