Allen-Bradley 800T-H3103A Selector Switch

Allen-Bradley 800T-H3103A Selector Switch is a 30 mm diameter panel-mount selector switch in the 800T family configured for three positions to control industrial circuits. Its compact footprint fits standard control panels, providing a durable means for operators to select between three defined states from a single actuator. Typically wired with compatible 800T contact blocks and mounted in a 30 mm enclosure, the device integrates with standard control-system hardware to route signals and enable straightforward process-state selection. As part of the Allen-Bradley Rockwell Automation catalog, the 800T-H3103A supports interchangeability with other 30 mm 800T switches, aiding spare-part management and maintenance in evolving automation footprints. Common applications include startup/shutdown selection, machine mode switching, and manual override in manufacturing lines such as conveyors, packaging machinery, and other process-control panels where a simple three-state selector is required.
