Eaton M22-WRLK-R Key-Operated Selector Switch, 2-Position, Maintained, Black Bezel, Silver Key, Red Indicator, 22.5 mm 216825

Industrial control panel builders and machine operators use the Eaton M22-WRLK-R key-operated selector switch to prevent unauthorized operation of critical equipment. Mounted in a standard 22.5 mm panel cutout, this maintained 2-position switch requires a key to change states, ensuring that only personnel with the key can start, stop, or change modes. The black bezel and silver key provide a professional appearance, while the red indicator offers clear visual status at a glance.

Good to know

The M22-WRLK-R is part of Eaton's modular M22 series, allowing combination with a wide range of contact blocks and accessories. The key is removable only in the OFF position, providing a clear safety interlock. For complete functionality, a compatible contact block must be ordered separately.
