Allen-Bradley 800T-NX54A Keyed Selector Switch

Allen-Bradley 800T-NX54A Keyed Selector Switch is a front-mounted 30 mm operator in the 800T family that ships with a keyed cylinder and key to lock the selected position. This keyed selector switch is designed for panel installations in industrial automation and provides secure mode selection in control circuits. It enables operators to select among multiple states consistent with the attached 800T contact blocks and accessories. The NX54A variant identifies the specific keying/mounting arrangement that works with the standard 800T hardware, enabling compatibility with mounting hardware, cylinder locks, and padlock attachments as needed. When integrated with compatible 800T contact blocks and enclosures, it delivers reliable operation in demanding environments where the machine state must be protected from unauthorized changes. This description covers the product’s function and typical use within an industrial control panel, without assuming features beyond the standard 800T line.
