Why Choose the ABB M2SS3-21G Selector Switch?
The ABB M2SS3-21G is a two-position illuminated momentary selector switch operator designed for industrial machinery, control panels and operator stations. Part of ABB's modular plastic 22 mm pilot-device range, it combines a short rotary handle with spring-return operation for temporary industrial command functions.
The M2SS3-21G features a green short rotary handle, green illumination and a chrome plastic bezel. Its momentary operating principle means the selector returns after the operator releases the handle rather than remaining latched, making it suitable for temporary machine commands and manual control functions.
Designed for a 22 mm mounting hole, the M2SS3-21G provides IP66 front protection and a NEMA 4X front protection classification. The operator has a mechanical durability of 0.5 million operations and is designed for use with ABB's modular contact and illumination components. ABB order code 1SFA611202R2102 identifies this exact M2SS3-21G Selector Switch.

Momentary Rotary Control with Green Visual Indication
Momentary selector switches are suited to industrial functions where a rotary command should only remain active while deliberately actuated. The ABB M2SS3-21G provides a two-position spring-return interface, automatically returning after release and making it suitable for temporary machine commands, manual control functions and other non-latching control operations.
The green illuminated short handle combines command and visual indication within a compact operator, while the chrome plastic bezel provides a coordinated industrial appearance. ABB's modular pilot-device architecture allows compatible contact blocks and illumination components to be selected according to the electrical requirements of the application.
Typical Applications
- Industrial machinery momentary command functions.
- Machine control panels and operator stations.
- Manual machine-control functions.
- Manufacturing and production equipment.
- Conveyor and material handling systems.
- Process control and automation equipment.
- OEM machinery and machine-building applications.
