Allen-Bradley 800T-H31A is a 30.5 mm (1.2 in) diameter two-position selector switch with a built‑in cylinder lock, designed for keyed operator control in industrial panels. It delivers a 1 normally open and 1 normally closed (1NO-1NC) contact configuration and uses a D018 key, enabling secure access and straightforward interlock or sequencing in machine-control circuits. This 800T model is built for rugged environments with a Type 4/13 enclosure rating and is part of the non‑illuminated 800T family, suitable for panel mounting where a keyed selector is required for safety and process control.
