Eaton M22-WRS-MS20 Key-Operated Selector Switch Actuator, 2-Position, Maintained, MS20 Key, Titanium Metal Front Ring, Black 111779

Key-operated selector switch actuator from the Eaton M22 series, offering secure 2-position maintained operation with a robust metal front ring in titanium finish. The MS20 key system allows removal only in the 0 position, preventing unauthorized switching and ensuring process safety in industrial control panels.

Advantages

This actuator is engineered for demanding environments, featuring a front protection rating of IP66, IP67, and IP69K, making it resistant to dust, powerful water jets, and temporary immersion. The metal front ring provides durability against mechanical impact, while the black actuator body offers clear visual indication. With a mechanical life exceeding 100,000 operations, it delivers long-term reliability in frequent-use applications.
