Allen-Bradley 800MR-A2BS Push Button Illuminated

Allen-Bradley 800MR-A2BS Push Button Illuminated is a 22 mm panel-mount pushbutton operator from Rockwell Automation’s 800MR family, designed for clearly visible signaling with built-in illumination and momentary contact. The A2BS variant follows the flush-head, black-cap style common to 800MR pushbuttons and is compatible with stab-terminal wiring for reliable field connections. Like other 800MR models, this illuminated pushbutton is intended for control-panel applications where a compact, robust operator provides a visual cue of actuation. Electrical ratings for 800MR pushbuttons generally include up to 300 V AC and up to 10 A maximum, supporting a wide range of industrial control circuits. The illuminated design enhances visibility in low-light or bright-glare environments, aiding quick confirmation of the switch state. Typical applications include start/stop control, machine signaling, and other control-panel signaling tasks in manufacturing environments, where a 22 mm operator with integrated illumination is desirable. As part of Rockwell’s legacy pushbutton hardware, the 800MR-A2BS is commonly available from Rockwell-authorized distributors and industrial suppliers, and may be used with corresponding contact blocks to tailor the configuration to specific logic requirements.
