ABB M2SS3-11G Safety Relay Module

ABB M2SS3-11G is a 2-position illuminated selector switch (Selector S) from ABB’s 22 mm modular plastic pilot-device family, designed for panel mounting in control cabinets and industrial equipment. The unit is green, with built-in illumination to indicate the chosen position, and it uses a short lever for compact operation; it is supplied without a contact block. The part is cataloged as 1SFA611202R1102, with an alternate catalog reference M2SS3-11G, aligning with ABB’s modular 22 mm product line. Typical applications include machine control panels and process lines where visual indication of the selector state is required, such as start/stop or mode selection, in environments that use ABB’s modular pilot devices.
