Allen-Bradley 800T-H33D2 Selector Switch 2 Position Main 1NC

Allen-Bradley 800T-H33D2 is a 30 mm diameter, two-position selector switch from the 800T family, designed for panel mounting in industrial control enclosures. It uses a cylinder-lock operator and offers a maintained action, ensuring the operator stays in the chosen position until manually moved. The device includes a main circuit contact configured as 1NC (one normally closed contact) in its two-position configuration, suitable for interlocks or stop-signaling in automation circuits. The operator is keyed to the D018 key code, providing controlled access for service and replacement. This model is commonly used in control panels to select machine modes or safety interlocks, and it accepts standard 800T accessories such as contact blocks and mounting hardware to tailor the signaling and auxiliary contacts as needed. With its robust 30 mm form factor and cylinder locking, the 800T-H33D2 offers a reliable, panel-mounted control solution for applications requiring two positions and a single NC main contact.
