Allen-Bradley 800MR-24JA4BRA Rotary Selector Switch

The Allen-Bradley 800MR-24JA4BRA is a 3-position illuminated rotary selector switch from the 800MR family, designed for 22.5 mm panel mounting and 24 V operation. It uses a maintained operator and provides a contact arrangement of 1 normally open and 1 normally closed contacts, with a standard red knob for the operator position. The unit is illuminated by an incandescent lamp and is designed for full-voltage operation at 24 V AC/DC. Rating is 10 A for typical control circuits, enabling reliable signal or motor-control sequencing across three selectable states. This configuration—3-position, illuminated, red knob, and 1 NO/1 NC contacts—makes it suitable for panel applications where a simple three-state control is required, such as start/stop or mode selection in industrial equipment.
