Allen-Bradley 800EM-SN22 2 Position Selector Switch

The Allen-Bradley 800EM-SN22 is a two-position selector switch designed for panel-mount control in industrial automation, providing a simple means to select between two discrete states within a control circuit. The SN22 designation identifies this specific variant within the Allen-Bradley 800E family, aligning with the series’ modular design and compatibility with other 800-series components and accessories. It is typically used to toggle operational modes or supply run/stop signaling, supporting common two-state applications in machines, conveyors, and process lines where a clear, manual control input is required. When installed, the switch is designed to pair with compatible contact blocks, mounting hardware, and operator knobs to form a complete control interface that can be integrated into existing control panels with minimal wiring. This combination of a compact form factor, straightforward electrical integration, and established replacement paths makes the 800EM-SN22 a practical choice for standard two-state control points in industrial environments.
