Allen-Bradley 800T-J4 Rotary Selector Switch Assembly

Allen-Bradley 800T-J4 Rotary Selector Switch Assembly is a 30.5 mm diameter, three-position selector switch from Rockwell Automation’s 800T family, designed for panel mounting in industrial control systems. This non-illuminated unit uses a spring-return mechanism (SR) to provide defined action and repeatable positioning for control sequences. The J4 designation identifies a 3-position, non-illuminated switch in the 800T line, intended to be used with compatible 800T contact blocks and mounting hardware to implement reliable operator input in machines, conveyors, and manufacturing equipment. The compact 30.5 mm footprint supports standard panel cutouts while delivering rugged mechanical action suited for harsh industrial environments. Typical applications include motor control panels, sequencing logic, and manual mode selection within automated lines, where a durable, compact rotary switch is preferred over larger controls. To ensure correct electrical configuration and positional count, verify compatibility with other 800T components and confirm the exact position mapping and mounting orientation for your enclosure, bearing in mind that 800T-J4 denotes a three-position, non-illuminated, spring-return unit in 30 mm format.
