Allen-Bradley 800T-H33 Cylinder Lock Selector Switch

The Allen-Bradley 800T-H33 Cylinder Lock Selector Switch is a two-position, 30.5 mm diameter operator with a keyed cylinder lock, designed for panel mounting in industrial control enclosures and safety circuits. As a cylinder-lock variant within the 800T family, the H33 provides secure retention of the selected position, requiring the proper key to rotate the operator and change states, which supports safe start/stop or mode-selection sequences. This non-illuminated device fits a standard 30.5 mm panel cutout and offers a mechanical, lockable solution for selecting control states in a wide range of automation equipment. It is well-suited for machine control panels, safety interlocks, conveyors, and packaging lines where a keyed selector helps prevent unauthorized or accidental changes to the operating state.
