Allen-Bradley 800T-J5KH4B Selector Switch 3 Position

Allen-Bradley 800T-J5KH4B is a 30 mm diameter selector switch operator for a three-position control, part of Rockwell Automation’s 800T family. This non-illuminated operator features a black cap with a white insert and a standard knob, and it uses a spring-return mechanism from the right. It mounts in a 30.5 mm hole and is compatible with enclosure types 1, 4, 12, and 13. The 800T-J5KH4B offers up to 1,000,000 mechanical cycles, with 25 G shock and 10 G vibration ratings, and it operates at temperatures down to -25 °C (storage to -40 °C) with about 50% humidity. The cam code is Standard, enabling compatibility with common 30 mm contact blocks to complete a three-position selector switch. This operator is designed for rugged industrial control panels where quick, repeatable position selection is needed for machine modes or control routing. Use cases include start/stop toggling, mode selection, or circuit routing in packaging lines, metalworking, and material handling systems. Note that this description covers the operator element only; a matching contact block is typically added to form a complete, functioning switch in a panel. The device’s robust metal construction and standard 30 mm form factor make it a practical choice for maintenance or upgrade projects involving 800T components.
