Why Choose the ABB M3SS8-11R Selector Switch?
The ABB M3SS8-11R is a robust three-position illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Part of ABB’s modular pilot device range, it features a red long-handle actuator with a black plastic bezel, providing clear visual identification and dependable manual control.
The M3SS8-11R combines maintained and momentary operation, with positions B and C maintained and spring return from position A to B. This operating arrangement makes it suitable for applications where a temporary command is required in one direction while retained selection is required in the other positions.
ABB order code 1SFA611217R1101 identifies this exact M3SS8-11R selector switch. The illuminated operator is designed for ABB’s modular pilot-device system and is supplied without a contact block, holder or lamp block, allowing the required switching and illumination components to be configured for the application.

Flexible Maintained and Momentary Machine Control
Selector switches provide operators with a straightforward interface for selecting machine modes and issuing control commands. The ABB M3SS8-11R combines retained selection with spring-return operation, allowing a single operator to perform both maintained and temporary control functions.
Positions B and C remain selected until the handle is deliberately moved, while position A automatically returns to B when released. The illuminated red long handle supports clear visual identification, while ABB’s modular construction allows compatible contact blocks and illumination components to be configured for the required control circuit.
Typical Applications
- Industrial machine control panels.
- Factory automation equipment.
- Operating-mode selection systems.
- Manual machine control functions.
- Conveyors and material handling equipment.
- Production and process machinery.
- OEM machinery and electrical control systems.
