Allen-Bradley 157317 Manual Rotary Selector Switch

The Allen-Bradley 157317 FM-F15-BE-SS Manual 2-Position Rotary Selector Switch is a panel-mount, maintained manual operation two-position selector with a rotary knob, used in industrial control and machine automation systems. It provides an 8-terminal configuration for multiple NO/NC contacts in a multi-pole arrangement, supporting flexible control circuit designs in control panels, motor starters, machinery, and operator stations requiring manual selection between two states such as ON/OFF, AUTO/MANUAL, or FORWARD/REVERSE. Rated voltage up to 600 VAC (current rating application dependent), it uses screw terminals and a rugged housing of industrial thermoplastic and metal, designed for high-cycle industrial duty with IP20 or higher protection depending on configuration. Common applications include motor control, machine control, and operator panels within industrial automation and electrical control systems.
