Allen-Bradley 800T-J41KA7A Keyed Selector Switch

Allen-Bradley 800T-J41KA7A is a 30 mm diameter, three-position keyed selector switch (KA7 cam) designed for maintained operation with a left-side lock. It provides three selectable states with standard contacts: one normally open (NO) and one normally closed (NC), and there are no blocking interlocks in positions 2 or 3. The back-mounted terminals are unguarded, aligning with typical 800T installation in industrial control panels. Electrical rating is up to 600 V AC and 10 A maximum, making it suitable for signaling and control circuits in machinery and conveyors. The KA7 cam enables precise indexing across the three positions, ensuring repeatable actuation, while the maintained action keeps the switch in the chosen state until it is rotated to another position. This model forms part of Allen-Bradley’s rugged 800T family of 30 mm selector switches and is commonly used for manual mode selection, start/stop control, or sequencing tasks where a simple three-position input is required.
