Why Choose the ABB M3SS3-11R Selector Switch?
The ABB M3SS3-11R is a robust three-position illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Supplied under ABB order code 1SFA611212R1101, it forms part of ABB’s modular plastic pilot device range and provides a combination of maintained and momentary operation for industrial machinery and process applications.
The M3SS3-11R features a red short-handle operator with a black plastic bezel. Its three-position A-B-C mechanism has positions A and B fixed, with spring return from C to B. This allows the selector to remain in positions A or B while providing a temporary command from position C that automatically returns to B when released.
Designed for ABB’s 22 mm modular pilot device system, the M3SS3-11R is an illuminated operator supplied without a contact block. It can be combined with compatible ABB holders, contact blocks and LED or lamp blocks to create a complete selector switch assembly tailored to the required industrial control circuit.
Key Advantages

Flexible Maintained and Momentary Control for Industrial Machinery
Selector switches combining maintained and momentary functions are useful where an operator needs both stable mode selection and a temporary command from the same control device. The ABB M3SS3-11R provides three positions, with A and B maintained and position C spring-returning to B, allowing the selected state to remain fixed while also supporting a momentary command.
ABB’s modular pilot-device construction allows the M3SS3-11R to be combined with compatible holders, contact blocks and illumination components according to the required electrical switching and indication arrangement. This flexibility makes the operator suitable for new machinery, control-panel construction, system integration, maintenance and replacement applications.
Typical Applications
- Industrial machinery control panels.
- Machine operating-mode selection.
- Maintained selection with a momentary command position.
- Automation and production equipment.
- Motor and process control stations.
- Manufacturing and assembly machinery.
- OEM electrical control systems and panel building.
