Allen-Bradley 800T-J17 Selector Switch

The Allen-Bradley 800T-J17 Selector Switch is a 30 mm diameter manual operator from Rockwell Automation, designed for use in industrial control panels to manually select among multiple circuit states. The J17 suffix identifies the operator style as a knob lever, a common 800T family variant that provides tactile actuation and a durable, repeatable feel through frequent cycling. This model is part of the 800T selector switch family and is typically paired with compatible 800T contact blocks and mounting accessories to create a compact, reliable input device for machinery, conveyors, or process equipment. Within the 800T line, the J17 knob-lever option offers one of several operator styles to match different mounting geometries and panel applications while preserving the same basic electrical interface and mechanical footprint as other 800T variants.
