Why Choose the ABB M2SSK3-304 Key Selector Switch?
The ABB M2SSK3-304 is a robust 2-position key-operated selector switch designed for controlled operator access in industrial machinery, automation systems and electrical control panels. Supplied under ABB order code 1SFA611282R3004, it forms part of ABB’s modular pilot device range and provides a durable keyed interface for industrial control functions.
The M2SSK3-304 features a black key-operated actuator, non-illuminated construction and a durable chrome-metal bezel. The M2SSK3 configuration provides a defined key-removal arrangement for applications where the key withdrawal position forms part of the machine or process operating procedure.
This particular order code is supplied as ABB’s random key selection configuration. The package contains 25 key-operated selector switches, each with a unique key code; ABB key codes 455, 421 and 3433-E are excluded from the random selection. The selector operators are supplied without contact blocks, allowing compatible ABB modular contact blocks and holders to be selected according to the required electrical switching function.

Individually Keyed Control for Industrial Automation
Key-operated selector switches provide a practical way to restrict changes to machine and process functions to personnel holding the appropriate key. The ABB M2SSK3-304 is particularly useful where multiple machines, panels or operator stations require individual keying rather than a common key shared between every control point.
Each M2SSK3-304 order-code package contains 25 key-operated selector switches with unique key codes, with ABB key codes 455, 421 and 3433-E excluded from the random selection. ABB’s modular pilot device architecture allows compatible contact blocks and holders to be configured according to the required electrical function, while the chrome-metal bezel and IP66 front protection provide a robust operator interface.
Typical Applications
- Industrial machinery control panels.
- Individually keyed machine controls.
- Restricted operating-mode selection.
- Authorised machine and process functions.
- Maintenance and service control stations.
- Factory automation systems.
- Process and motor control panels.
- OEM equipment requiring individually keyed operator access.
