Allen-Bradley 800T-H48 Key Selector Switch is a non-illuminated, approximately 30 mm (30.5 mm variants are cited in Rockwell literature) diameter selector in the 800T family that uses a cylinder lock and a key for operation. The H48 variant is a two-position (2P) cylinder-lock selector designed for panel mounting in industrial control cabinets, enabling quick switching between two discrete states in a circuit or control sequence. This compact device is commonly paired with 30 mm panels and compatible 800T accessories, and is selected for applications such as mode selection, start/stop control, or basic two-state operator input in automation systems.
