Allen-Bradley 800EM-SR38 Switch is a spring-return rotary selector switch in the 800EM family, designed for panel-mounted state selection in industrial automation. It functions as a discrete-state selector, enabling an operator to switch between predefined control modes or functions within a machine control circuit. As part of the 800E/800EM lineup, it shares standard mounting interfaces with other 22 mm family devices, supporting consistent operator interfaces across control panels. The SR38 designation identifies the spring-return variant of this selector switch, suitable for applications that require actuation to return automatically when released.
