Why Choose the ABB M3SS4-11L Selector Switch?
The ABB M3SS4-11L is a three-position maintained illuminated selector switch designed for industrial control panels, machinery and automation systems. Part of ABB's modular plastic pilot-device range, it features a blue long-handle rotary actuator with a black plastic bezel for clear operator control and visual indication.
The M3SS4-11L provides three maintained positions, A, B and C, allowing the selected position to remain mechanically set after the operator releases the handle. This operating principle makes it suitable for mode selection, directional commands and other machine-control functions where a persistent operator selection is required.
Designed for standard 22 mm panel mounting, the M3SS4-11L is an illuminated modular operator supplied without a contact block. Its modular construction allows compatible ABB contact and illumination components to be selected according to the required electrical control and indication function.
Key Advantages
- Three-position maintained operation provides stable A, B and C selections.
- Blue illuminated long-handle actuator combines rotary control with visual indication.
- Black plastic bezel provides a practical industrial operator interface.
- Standard 22 mm panel mounting supports straightforward control-panel integration.
- IP66 protection supports use in demanding industrial environments.
- Modular ABB construction allows compatible contact and illumination components to be configured for the application.
- Long-handle design provides an easily operated interface for machinery and automation controls.

Reliable Maintained Control for Industrial Machinery
Three-position maintained selector switches allow an operator to choose between defined machine states and leave the selected command mechanically engaged. The ABB M3SS4-11L provides A, B and C positions with maintained operation, making it suitable for applications where the control must remain in its selected state until deliberately changed.
The M3SS4-11L forms part of ABB's modular plastic pilot-device system, allowing machine builders and panel designers to combine the operator with compatible contact and illumination components. Its blue illuminated long handle, black plastic bezel and standard 22 mm format provide a compact and clearly identifiable operator interface for industrial machinery and automation equipment.
Typical Applications
- Industrial machinery control panels.
- Three-position operating-mode selection.
- Forward / neutral / reverse control functions.
- Manual / off / automatic selection.
- Manufacturing and production equipment.
- Material handling and conveyor systems.
- OEM machinery and industrial automation systems.
