Allen-Bradley 800T-J4A Selector Switch 3 Position Maintained

Allen-Bradley 800T-J4A is a 30 mm diameter selector switch designed for panel mounting in industrial control applications. This three-position operator provides a straightforward input for manual mode selection, using a standard contact block configuration of 1 normally open (NO) and 1 normally closed (NC) contact. The operator is offered with a knob or wing lever and a white insert, aligning with the 800T family’s 30 mm facial style and compact footprint. As part of the 800T line, the J4A variant supports common cam and block configurations and is referenced in distributor listings alongside KB7 cam options. This combination of compact size, defined contact arrangement, and versatile operator options makes the 800T-J4A a practical choice for control panels and machinery that require a reliable, mechanical selector input. Note that exact electrical ratings and mounting details can vary by cam and block configuration; consult Rockwell Automation documentation or a trusted distributor for your specific installation.
