Square D 800T-H4A 2-Position Maintained Selector Switch

Square D 800T-H4A 2-Position Maintained Selector Switch is a compact 30 mm diameter operator designed for control panels, delivering two latched positions to route control circuits with reliability. This model is a 2-position maintained selector offering a 1 normally open and 1 normally closed contact configuration, enabling straightforward on/off or start/stop logic within a single device. It uses a standard cam and a white insert for clear position indication, and the terminals are unguarded to simplify wiring. Documented across Rockwell Automation (Allen-Bradley) pages and various distributor catalogs, the 800T-H4A variant is listed as a 30 mm selector switch in the 800T family, reflecting its compact form factor and intended panel-mount use in industrial automation. Common applications include panel-mounted control circuits, motor-start and stop circuitry, and process control selections where a durable, two-position control is required in a single device.
