Eaton M22-WRS-MS10-A1 Key-Operated Selector Switch, 2 Positions, Maintained, MS10 Key, 22.5mm Mounting, Black/Silver, IP66/IP67/IP69K 111776

Control access to critical machine functions with the Eaton M22-WRS-MS10-A1 key-operated selector switch. In industrial control panels, conveyor systems, and automated production lines, operators use this switch to change between two operating modes—such as manual and automatic—only when authorized with the MS10 key. The key is removable in the left position (position 0), preventing unauthorized switching and ensuring safe, controlled operation.

Why choose it

The M22-WRS-MS10-A1 combines robust construction with a secure key mechanism. Its IP66/IP67/IP69K front protection withstands washdowns and harsh industrial environments, while the modular M22 design allows easy integration with contact blocks and LED elements. The maintained action ensures the selected position stays active until deliberately changed, reducing accidental mode shifts.

Ideal use cases

• Access control for critical machine modes in manufacturing
• Authorized switching in conveyor and packaging systems
• Safety-relevant mode selection in process automation
• Control panels requiring restricted operation

Good to know

This actuator is part of the Eaton M22 series, known for its modularity and reliability. It is compatible with M22 contact blocks and LED elements, allowing flexible configuration. The MS10 key is a standard Eaton key type, and the switch is designed for a 22.5 mm mounting hole.
