Allen-Bradley 800T-J19A Selector Switch Lever Knob

Allen-Bradley 800T-J19A is a 30 mm diameter three-position selector switch from the 800T family designed for panel mounting in industrial control systems. It uses a knob lever with spring return from the right and includes a white insert along with cam and contact blocks, enabling a compact, modular operator for control panel assemblies. The standard contact configuration is 1 normally open (NO) and 1 normally closed (NC), providing straightforward on/off signaling in each of the three positions. With three selectable positions (left, center, right), this switch supports simple mode or sequence selection in automation tasks, and the spring-return right-hand action designates the right position as momentary. Compatible with Rockwell Automation’s 800T catalog framework, the 800T-J19A is intended to work with the corresponding cam blocks and contact assemblies to define the electrical state in each position, making it well-suited for machine control panels, start/stop logic, and process sequencing where a compact 30 mm operator is required.
