Why Choose the ABB M2SSK1-102 Key Selector Switch?
The ABB M2SSK1-102 is a two-position maintained key-operated selector switch designed for industrial machinery, automation systems and electrical control panels where controlled access to a switching function is required. Part of ABB’s modular plastic pilot-device range, it features a black key-operated actuator with a black plastic bezel.
The M2SSK1-102 provides two maintained positions with no spring return, so the selected position remains engaged until deliberately changed with the key. Its Ronis 421 key can be removed in both operating positions, providing convenient keyed control for authorised machine functions and operating modes.
ABB order code 1SFA611280R1002 identifies this exact M2SSK1-102 key selector switch. The non-illuminated operator uses a standard 22 mm mounting hole, provides IP66 front protection and is supplied without a contact block, allowing compatible ABB modular contacts to be selected for the required control circuit.
Key Advantages
- Two-position maintained key selector for controlled industrial switching.
- Ronis 421 key code provides keyed access to machine functions.
- Key removable in both positions for flexible operating procedures.
- No spring return, allowing the selected position to remain engaged.
- 22 mm mounting format simplifies integration into industrial control panels.
- IP66 front protection and NEMA 4X classification support demanding environments.

Controlled Key-Operated Selection for Industrial Machinery
Key-operated selector switches are useful where access to a machine function or operating mode should be restricted to personnel holding the appropriate key. The ABB M2SSK1-102 provides two maintained positions and uses a Ronis 421 key that can be removed from either position, allowing the selected state to remain set after the key is withdrawn.
Its black plastic bezel, standard 22 mm panel format and IP66 front protection make the M2SSK1-102 suitable for industrial operator panels and machinery. ABB’s modular construction allows compatible contact blocks to be selected separately according to the electrical switching requirements of the application.
Typical Applications
- Industrial machine control panels.
- Authorised operating-mode selection.
- Factory automation equipment.
- Machine enable and control functions.
- Production and process machinery.
- Conveyors and material handling systems.
- Industrial operator stations.
- OEM machinery and electrical control systems.
