Allen-Bradley 800MR-J631BLA 3-Position Keyed Switch

Allen-Bradley 800MR-J631BLA is a non-illuminated, 3-position selector switch from the 800MR family that fits a 22.5 mm panel opening and uses a cylinder lock for secure operation. It provides three operator positions—left, center (lock-in), and right—with spring return from the left and right positions, so the actuator returns to center when released; the center position is a locked, maintained state. The unit employs a standard T100 key code with a B cam, and its contact arrangement is 1 normally open (N.O.) and 1 normally closed (N.C.), featuring stab terminals for quick-connect termination. It is rated for up to 300 V AC and 10 A, making it suitable for control and interlock applications in industrial equipment where a keyed selector is required to prevent unintended changes. As part of Rockwell Automation’s 800MR lineup, this switch delivers durable, keyed operator input for machine control panels without illumination.
