ABB M2SS4-11G is a two-position illuminated maintained selector switch operator with a green long rotary handle, black plastic bezel and IP66 front protection for industrial machinery and control-panel applications.
The ABB M2SS4-11G is a two-position illuminated maintained selector switch operator designed for industrial machinery, control panels and operator stations. Part of ABB's modular 22 mm pilot-device range, it combines a prominent long rotary handle with maintained operation for dependable two-state control and selection functions.
The M2SS4-11G features a green long rotary handle, green illumination and a black plastic bezel. Its maintained B/C operating principle means both selector positions are stable, so the chosen position remains selected after the operator releases the handle.
Designed for a 22 mm panel mounting system, the M2SS4-11G provides IP66 front protection and has a specified mechanical durability of 500,000 operations. The modular operator is designed for use with separately selected ABB contact blocks and an illumination block, allowing the completed control device to be configured for the application. ABB order code 1SFA611203R1102 identifies this exact M2SS4-11G Selector Switch.

Maintained Rotary Selection with Green Visual Indication
Maintained selector switches are used where an operator needs to choose a machine or process state that remains selected after the handle is released. The ABB M2SS4-11G provides two stable B/C positions through a prominent long rotary handle, making it suitable for operating-mode selection, circuit selection and other two-state industrial control functions.
The green illuminated actuator combines command and visual indication within a single operator, while the black plastic bezel provides a coordinated industrial appearance. ABB's modular pilot-device architecture allows compatible contact blocks and illumination components to be selected according to the electrical requirements of the application, providing flexibility for machine builders, panel builders and automation engineers.
Typical Applications

Machine control panels and operator stations.
Manufacturing and production equipment.
Conveyor and material handling systems.
Process control and automation equipment.
Control desks and local operator interfaces.
OEM machinery and machine-building applications.
