Why Choose the ABB M2SS2-21L Selector Switch?
The ABB M2SS2-21L is a two-position illuminated maintained selector switch operator designed for industrial machinery, control panels and operator stations. Part of ABB's modular 22 mm pilot-device range, it combines positive rotary selection with illumination capability in a compact industrial operator.
The M2SS2-21L features a blue short rotary handle and a chrome plastic bezel. Its maintained switching function means the selector remains in the chosen position after the handle is released, providing a stable two-state interface for machine and process control applications.
Designed for a 22 mm mounting hole, the M2SS2-21L provides IP66 front protection and a NEMA 4X protection classification. Its modular construction allows compatible ABB contact blocks and illumination components to be selected separately according to the required control circuit. ABB order code 1SFA611201R2104 identifies this exact M2SS2-21L Selector Switch within ABB product group 312001-Pilot Devices (Secrl).

Maintained Rotary Selection with Blue Visual Indication
Maintained selector switches are suited to applications where an operator needs to choose a machine or process state that remains selected after the handle is released. The ABB M2SS2-21L provides two stable switch positions through a compact blue short rotary handle, making it suitable for mode selection, circuit selection and other two-state industrial commands.
The operator is suitable for illumination, allowing visual status indication to be incorporated into the control interface. ABB's modular pilot-device architecture enables compatible contact blocks and illumination components to be selected according to the electrical requirements of the application, providing a flexible solution for machine builders, panel builders and automation engineers.
Typical Applications
- Industrial machinery mode selection.
- Machine control panels and operator stations.
- Manufacturing and production equipment.
- Conveyor and material handling systems.
- Process control and automation equipment.
- Control desks and local operator interfaces.
- OEM machinery and machine-building applications.
