Allen-Bradley 800MR-A3 Push Button

Allen-Bradley 800MR-A3 Push Button is a 22 mm round operator from Rockwell Automation's 800MR family, featuring a grey bezel and momentary actuation. The A3 configuration provides a dual-contact block: one normally open and one normally closed contact, allowing signaling of both states from a single push button in control circuits. Designed for panel mounting in standard 22 mm holes, it is commonly used in industrial machines and automation panels for start/stop and interlock functions, and it can be paired with other 800MR modules to form a compact operator station. As part of the 800MR line, this push button integrates with Rockwell's push-button accessories and contact blocks to tailor a control solution to the application's needs.
