Why Choose the ABB M3SS1-11R Selector Switch?
The ABB M3SS1-11R is a robust three-position illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Supplied under ABB order code 1SFA611210R1101, it forms part of ABB’s modular 22 mm pilot device range and provides reliable manual selection between multiple machine functions or operating modes.
The M3SS1-11R features a red illuminated short-handle operator with a black plastic bezel and maintained switching action. Its three-position A-B-C operating principle allows the selector to remain in the chosen position until manually changed, providing clear physical and visual indication as part of an industrial operator interface.
Designed for installation in a standard 22 mm mounting hole, the M3SS1-11R is supplied as a modular operator without a contact block or lamp. It can be combined with compatible ABB holders, contact blocks and LED or lamp blocks to create a complete illuminated selector switch assembly for industrial control applications.

Reliable Three-Position Control for Industrial Machinery
Three-position selector switches provide operators with a straightforward method of choosing between multiple predefined machine functions or operating modes. The ABB M3SS1-11R uses a maintained A-B-C mechanism, allowing the selected position to remain mechanically set until the operator deliberately changes it.
ABB’s modular pilot-device construction allows the M3SS1-11R to be combined with compatible holders, contact blocks and LED or lamp blocks according to the required control circuit. This modular approach makes the selector suitable for new machinery, control-panel construction, system integration, maintenance and replacement applications.
