Allen-Bradley 800T-J43A Selector Switch 3 Position Keyed Right

Allen-Bradley 800T-J43A is a 30 mm, three-position selector switch with maintained action, designed for panel-mounted control in industrial automation. This right-hand locking variant secures the operator in the chosen position and provides a single normally open and a single normally closed contact set (1-NO, 1-NC) for signaling and control within a compact device. The switch uses a KB7 cam and ships without guards in the standard terminal configuration, with no interlock blocks in positions 2 or 3 to allow full three-state operation. As part of the 800T family, the 800T-J43A is a rugged operator suitable for mode selection, start/stop sequencing, or other three-state control tasks in automation equipment. The designation “1-NO 1-NC” confirms its dual-branch contact arrangement, enabling combined control logic from a single actuator, while the maintained action ensures the circuit remains in the selected state until manually changed. Commonly used in control panels where a dedicated, lockable selector is required, this model integrates seamlessly with Allen-Bradley’s 800T lineup and is chosen for applications needing a reliable, key-accessed three-position switch with straightforward wiring on terminals.
