Allen-Bradley 800T-J17A Selector Switch Lever

Allen-Bradley 800T-J17A Selector Switch Lever is a 30 mm diameter, non-illuminated selector switch from the 800T family, designed for panel mounting in industrial controls. The operator is a knob lever (J17A) that provides distinct positioning with a positive tactile feel. It incorporates one normally open and one normally closed contact (1NO 1NC) in a two-pole arrangement, enabling simple control of start/stop or mode selection circuits. This lever-style operator is compatible with standard 800T cam and contact blocks, allowing flexible wiring and staking of different control configurations within 30 mm operator families. The 800T-J17A is intended for use in machine control panels, packaging lines, conveyors, and manufacturing equipment where a compact, rugged 3-position switch is required for manual control of electrical circuits. In practice, technicians install the J17A knob lever into a 800T-series housing and wire it with corresponding cam and contact blocks to tailor the switch for a given control logic and panel layout.
