Allen-Bradley 800T-J5KA7B Selector Switch 3-Position

Allen-Bradley 800T-J5KA7B is a 30 mm diameter selector switch in the 800T family, engineered for panel mounting in industrial control systems. It provides three detented positions and a spring-return operator that resets to the home position when released, with the J5KA7B configuration indicating a KA7 cam. This variant is cataloged as No Guards on terminals, a descriptor that informs its interface with wiring and enclosure requirements in standard control panels. The 800T line is designed to fit compact, modular control assemblies, making this switch a common choice for three-state operations such as mode selection or start/stop signaling within automation racks and machines. The KA7 cam pairing ensures consistent actuation sequencing with compatible contact blocks, enabling reliable interlocking and state indication in a compact 30 mm package. For repairs or replacements, this model should be matched to other KA7 cam variants within the 800T family to preserve intended detent positions and operator feel.
