Allen-Bradley 800TC-J44B 3-Position Cylinder Lock Selector Switch

Allen-Bradley 800TC-J44B is a 30 mm cylinder-lock three-position selector switch in the 800T family, designed for panel mounting in industrial control applications. It provides three operator positions—Left, Center, and Right—each of which can be locked with a keyed cylinder to prevent accidental changes during operation. The unit employs a standard contact configuration of 2 normally open and 2 normally closed contacts, enabling flexible control logic for start/stop sequences, interlocks, and safety gating within automation circuits. As a cylinder-lock variant, it is intended for environments where operator access must be restricted to preserve process integrity or machine safety. With a 30 mm mounting diameter, it fits common control panel cutouts and is compatible with Rockwell Automation 800T-style assemblies and their typical cam configurations for reliable actuation. Common applications include control panels for conveyors, packaging lines, robotic work cells, and general machine control where a secure, multi-position selector is required.
