Why Choose the ABB M2SS5-21C Selector Switch?
The ABB M2SS5-21C is a robust two-position illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Supplied under ABB order code 1SFA611204R2108, it forms part of ABB’s modular 22 mm pilot device range and provides reliable manual selection of machine functions and operating modes.
The M2SS5-21C features a clear illuminated long-handle operator with a chrome-plastic bezel and maintained switching action. Its modular construction allows the operator to be combined with compatible ABB holders, contact blocks and illumination components, providing a flexible solution for industrial control stations and electrical panels.
Designed for installation in a standard 22 mm mounting hole, the M2SS5-21C provides two maintained selector positions, A and C. The operator remains in the selected position until manually changed, while its illuminated design enables visual indication when combined with compatible ABB illumination components.

Reliable Operator Control for Industrial Machinery
Selector switches provide operators with a straightforward and reliable method of choosing between predefined machine functions or operating modes. A maintained two-position selector such as the ABB M2SS5-21C remains in the selected position until manually changed, providing a clear physical indication of the selected control state.
ABB’s modular pilot-device system allows the M2SS5-21C to be combined with compatible holders, contact blocks and illumination components. Its illuminated clear operator can provide visual signalling as part of a correctly configured assembly, making the selector suitable for new machinery, control-panel construction and replacement applications.
Typical Applications
- Industrial machinery control panels.
- Automation and production equipment.
- Machine operating-mode selection.
- Illuminated status and function selection.
- Motor and process control stations.
- Manufacturing and assembly equipment.
- OEM electrical control systems and panel building.
