Why Choose the ABB M2SSK3-103 Key Selector Switch?
The ABB M2SSK3-103 is a two-position momentary key-operated selector switch designed for industrial machinery, automation systems and electrical control panels where access to a control command needs to be restricted. Part of ABB’s modular pilot-device range, it features a black key-operated actuator with a black plastic front bezel.
The M2SSK3-103 provides spring-return operation across its two-position arrangement, making it suitable for temporary keyed commands rather than retained mode selection. It uses a Ronis 3433-E key, providing a defined key code for controlled machine and equipment operation.
ABB order code 1SFA611282R1003 identifies this exact M2SSK3-103 key selector switch. The non-illuminated operator uses the standard 22 mm pilot-device format, provides IP66 front protection and is designed for use with separately selected ABB modular contact blocks.

Controlled Momentary Key Operation for Industrial Machinery
Momentary key selector switches provide a practical way to restrict temporary machine commands to personnel holding the appropriate key. The ABB M2SSK3-103 combines keyed operation with spring return, making it suitable for functions where the control should automatically return after the operator releases the key-operated selector.
The Ronis 3433-E key code provides a defined keyed interface, while the black plastic bezel, 22 mm pilot-device format and IP66 front protection suit industrial control-panel installations. ABB’s modular construction allows compatible contact blocks to be selected separately according to the required electrical switching arrangement.
Typical Applications
- Industrial machine control panels.
- Authorised momentary machine commands.
- Factory automation equipment.
- Key-controlled start or enable functions.
- Production and process machinery.
- Conveyors and material handling systems.
- Industrial operator stations.
- OEM machinery and electrical control systems.
