Why Choose the ABB M2SS4-21R Selector Switch?
The ABB M2SS4-21R is a robust two-position illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Supplied under ABB order code 1SFA611203R2101, it forms part of ABB’s modular 22 mm pilot device range and provides a clear, durable operator interface for machine control and signalling applications.
The M2SS4-21R features a red 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 flexibility when configuring control stations and electrical panels.
Designed for installation in a standard 22 mm mounting hole, the M2SS4-21R provides two selector positions and is suitable for illumination. Its maintained operating principle keeps the selector in the chosen position until it is manually moved, making it well suited to mode selection and other persistent machine-control commands.

Reliable Operator Control for Industrial Machinery
Selector switches provide operators with a simple and reliable method of choosing between predefined machine functions or operating modes. A maintained two-position selector such as the ABB M2SS4-21R remains in the selected position, providing clear physical indication of the chosen control state.
ABB’s modular pilot-device system allows selector switch operators to be combined with compatible holders, contact blocks and illumination components. This modular approach makes the M2SS4-21R suitable for new control-panel construction as well as maintenance and replacement applications in industrial automation systems.
Typical Applications
- Industrial machinery control panels.
- Automation and production equipment.
- Machine operating-mode selection.
- Motor and process control stations.
- Manufacturing and assembly equipment.
- OEM electrical control systems.
