Eaton 216812 M22-WLK-W illuminated selector switch 2 positions white content_copy

The article Eaton M22-WLK-W is a toggle switch from the RMQ-Titan series, designed as a lighted selector switch with two positions. It serves as a single unit for operation and signaling in industrial systems and is designed for use in control and switching installations. The device features a knob handle in white color and a front ring with titanium finish, allowing it to visually integrate into modern control panels. The design is momentary and enables both latching and momentary functions, with the switch remaining locked in both positions. The front dimension is 29.7 mm, defining the mounting size for standard module slots.

Applications
This switch is designed for use in industrial environments, particularly in systems requiring high mechanical and chemical resistance. The protection rating IP66 ensures complete dust tightness and protection against strong water jets, making it suitable for outdoor use or in humid production environments. Certification according to IEC/EN 60947 and VDE 0660 confirms compliance with relevant standards for switching devices and safety technology. Integration with the SmartWire-DT system enables integrated communication in modern control systems, with RMQ-SWD connections ensuring the link.

Functions and Equipment in Detail
The white knob handle color provides clear visual identification, while the titanium front cover offers a robust and aesthetically pleasing appearance. The latching/momentary function allows for temporary actuation (momentary) as well as permanent latching in either of the two positions. Compatibility with coded parts M22-XC-Y enables interchangeability within the product family, simplifying maintenance and expansion of control panels.

Technology Explained Simply
The protection rating IP66 means the device is protected against dust and water jets from any direction. This makes it suitable for harsh environments, such as in manufacturing, machine building, or process engineering. The plastic housing is lightweight, resistant to mechanical stress, and corrosion-resistant. The front dimension of 29.7 mm corresponds to the standard for mounting in 22-mm module systems, enabling universal installation in existing control panels. The mounting depth of 1.9 cm is designed for installation in standard module slots.

Compatibility and Accessories
The device is part of the RMQ-Titan system and can be combined with various accessories to extend functionality. These include, for example, LED elements in different colors (red, blue, white) for signaling, actuator additions with label holders (e.g., “ON”, “OFF”, “HAND-0-AUTO”) for position identification, and contact elements (e.g., 1S front, 1NC bottom) for electrical connections. Additionally, hoods, add-on enclosures, and mounting adapters are available to adapt the device to specific requirements. Connection to SmartWire-DT enables digital integration into higher-level control systems.

Mounting and Installation
Mounting is done in standard module slots with a front width of 29.7 mm. The mounting depth of 1.9 cm requires sufficient space in the enclosure. Installation is performed by inserting into the module system, with electrical connections made via integrated terminal blocks or through the SmartWire-DT interface. The use of actuator additions or LED elements requires additional mounting, which depends on the module type and is done via plug connections or screw connections.

Advantages in Operation
The switch offers high mechanical stability and long service life due to robust materials and precise manufacturing. The IP66 protection rating protects against environmental influences, increasing reliability in demanding environments. Compatibility with SmartWire-DT enables digital control and diagnostics, simplifying maintenance and fault detection. Interchangeability with coded parts M22-XC-Y reduces effort for replacement or expansion work. Clear identification via color and label holders improves operability and reduces error sources.
