Allen-Bradley 800T-24JA2KB7TX Selector Switch

The Allen-Bradley 800T-24JA2KB7TX is a 30 mm, three-position selector switch designed for panel mounting in industrial control systems. It operates from 24 V AC/DC and uses an incandescent lamp to provide amber illumination, with a maintained action that latches the selector in the chosen position until the operator changes it. The switch features a KB7 cam, a standard knob, and 1-NO 1-NC logic reed contacts, enabling straightforward signaling and interlock logic in control circuits. It is specified without terminal guards and without blocking in position 3, simplifying wiring and ensuring reliable access to the terminals even with the knob in the third position. The 30 mm footprint fits conventional panel cutouts and supports compact layouts where space is at a premium. Typical uses include mode selection, start/stop sequencing, and visible amber-state indication on control panels in manufacturing and automation environments, where quick recognition of the current state is critical for operators and for sequencing logic in PLC-based systems.
