Why Choose the ABB M3SSK2-103 Selector Switch?
The ABB M3SSK2-103 is a robust three-position key-operated selector switch designed for industrial control panels, machinery and automation applications where controlled access to operating functions is required. Supplied under ABB order code 1SFA611284R1003, this modular pilot device combines secure key operation with ABB's flexible 22 mm control and signalling platform.
The M3SSK2-103 features a maintained three-position mechanism, allowing the selected operating position to remain engaged after the key has been turned. The key can be removed in centre position B only, making the selector particularly suitable for applications where machine operating modes or control functions need to be restricted to authorised personnel.
Featuring key code 73 / Ronis 3433-E, a black key actuator and black plastic bezel, the M3SSK2-103 is supplied as a non-illuminated operator without a contact block. Its modular construction enables compatible ABB holders and contact blocks to be selected separately according to the required electrical switching arrangement.

Secure Control for Industrial Machinery
Key-operated selector switches provide an effective way to restrict machine and process functions to authorised personnel. Requiring the appropriate key helps prevent unintended changes to operating modes, maintenance functions or other controlled processes while providing operators with a straightforward manual control interface.
The ABB M3SSK2-103 combines a maintained three-position mechanism with ABB's modular pilot device architecture. Its 22 mm panel format and separately configurable contact blocks make it suitable for integration into new machinery as well as industrial control-panel and automation projects requiring secure mode selection.
