Allen-Bradley 800EM-SM32 Maintained Selector Switch

The Allen-Bradley 800EM-SM32 Maintained Selector Switch is a three-position control designed for industrial panels. It uses a maintained operation, so the knob stays in the selected position until rotated to another state, providing a deterministic input for machine logic. The unit is identified by part number 800EM-SM32 and features a black control knob. With three discrete positions, it enables simple selection among circuit paths or operating modes in automated equipment and manufacturing lines. This model forms part of Allen-Bradley’s 800-series selector switches, offering a standard mechanical interface for manual control. The 800EM-SM32 is suitable where a three-position maintained selector input is required, and it can serve as a replacement in legacy control panels that specify a three-position maintained 800-series switch. Buyers typically use this switch to implement start/stop sequencing, mode selection, or manual override states in a variety of industrial applications.
