The M22S-WS-MS* key switch from Eaton belongs to the RMQ-Titan range and is designed as a single unit for industrial control and signaling applications. It features a key-operated push-button design, enabling selection between two positions. The locking function is selectable, allowing the operation to be configured according to requirements. The device is not intended for use in locking systems. The front dimension is 29.7 mm, with the front ring finished in black. The key switch is equipped with an integrated RMQ-SWD connection, enabling connection to the SmartWire-DT system. The latching and push functions are integrated, allowing flexible operation. The key is removable and can be converted using coding adapters of type M22-XC, ensuring interchangeability with coded parts of the M22-XC-Y series. The device is supplied with one key.

Key switch is the central control element used in industrial control systems for selecting operating states. The push-button design means the position is active only while the key is pressed, enabling temporary functions. The selectable locking allows the switching function to be defined according to application, offering flexibility when integrating into existing systems. The IP66 protection rating ensures high protection against dust and water, including splashing water from all directions, making the device suitable for outdoor use as well as in humid or dusty environments.

SmartWire-DT is a decentralized fieldbus system that enables communication between control elements and the central control system. Connection via RMQ-SWD interfaces allows direct integration into SmartWire-DT networks, enabling the control function to be monitored and controlled via the control system. The front dimension of 29.7 mm matches the standard for built-in devices in enclosures, enabling compact installation. The black front ring provides clear visual distinction and is suitable for integration into standardized control panels.

The key switch is interchangeable with coded parts M22-XC-Y, enabling flexible expansion of functionality, for example by using coded keys for access control. The convertibility with coding adapters M22-XC extends application possibilities, as the key switch can be adapted to different security requirements. The latching/push function allows selection between a permanent state (latching) and a temporary state (push), depending on requirements.

Standards and regulations such as IEC/EN 60947 and VDE 0660 ensure compliance with international standards for switching devices and safety technology. These standards include requirements for electrical safety, operational safety, and mechanical robustness. Compliance with these standards ensures the device can be reliably and safely used in industrial applications.

Compatible accessories include various push-button accessories such as label carriers (e.g. M22S-ST-F67, M22S-ST-X93, M22S-ST-GB6) for function identification, and mounting adapters (e.g. M22-ADC4, M22-ADC) for secure installation. Additional components such as contact elements (e.g. M22-CKC01, M22-K01), caps (e.g. M22-H4, M22-H2), and coded part sets (e.g. M22-XC-R) extend functionality and customization options. Combining these accessories enables individual design of the control surface and adaptation to specific requirements.

Installation is carried out in standard enclosures or control panels, with the front dimension of 29.7 mm being standardized. Integration into SmartWire-DT systems requires no additional adapters, as the connections are already integrated. Operation is via the key, which is removable and can thus be securely stored when not in use. Use in environments with high mechanical stress or humidity is possible due to the IP66 protection rating.

Operational advantages include high reliability, easy integration into SmartWire-DT systems, and flexibility through interchangeability with coded parts. Clear labeling via label carriers and mechanical robustness ensure long service life and low maintenance. Compliance with standards IEC/EN 60947 and VDE 0660 ensures safety and compatibility in industrial installations.

The M22S-WS-MS* key switch is therefore a robust, flexible, and safety-compliant control element for industrial applications, suitable for use in standard environments as well as demanding conditions. The combination of mechanical stability, electrical reliability, and digital connectivity makes it a suitable component for modern control systems.
