Allen-Bradley 800T-H4A Selector Switch 2 Position

The Allen-Bradley 800T-H4A Selector Switch is a 30.5 mm panel-mount two-position selector from the 800T family. It provides a single-pole, double-throw (SPDT) contact arrangement with one normally open and one normally closed contact, enabling a clean changeover between two discrete circuits as the knob is rotated between positions. The unit is delivered with a white insert and a standard cam, and it wires on terminals rather than using flying leads, making it straightforward to mount on a control panel. It features a spring-return action that returns to the left-hand position when released, suitable for momentary leftward selection in control circuits such as start/stop or mode selection. Designed for durable industrial use, the 800T-H4A occupies a compact 30.5 mm enclosure footprint, matching other 800T operators in the same family. This model is commonly paired with 30 mm 800T hardware and compatible mounting kits to create a compact, reliable control interface in machinery and equipment. With its robust mechanical design and clear, tactile detents, it provides dependable manual control in environments where space is at a premium and quick, repeatable operator input is essential.
