Eaton M22S-WRK4 Selector Switch Actuator, Black, 3-Position, Maintained, Plastic Front Ring 279432

Industrial control panel builders and machine operators use the Eaton M22S-WRK4 as a front-mounted selector switch actuator. It mounts into a standard 22.5 mm panel cut-out and works with Eaton M22 contact blocks to provide a maintained, 3-position switching function. The black knob and plastic front ring make it suitable for control circuits where a robust, non-illuminated selector is required.
