Allen-Bradley 800T-J44A Keyed Selector Switch

The Allen-Bradley 800T-J44A is a 30 mm, three-position keyed selector switch designed for industrial control panels. It features a maintained (non-spring-return) operation with a removable key that can be removed in all three positions, providing lockout capability for safety and process control. The switch includes a single normally open and a single normally closed contact block, enabling simple start/stop and interlock functions in a control circuit. The rugged 800T operator is intended for panel mounting in demanding environments and is compatible with the 800T family’s modular contact blocks; the associated contact block is rated for NEMA 4/13 service, suitable for washdown and harsh environmental conditions. This part, cataloged as 800T-J44A, is commonly used for machine start/stop selectors, process isolations, and safety interlocks, and can be paired with compatible 30 mm 800T accessories to tailor the configuration to specific applications.
