1SFA611203R1101 ABB M2SS4-11R 2-Position Illuminated Maintained Selector Switch

Why Choose the ABB M2SS4-11R Selector Switch?

The ABB M2SS4-11R 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 a long rotary handle with maintained operation for dependable two-state control and selection functions.

The M2SS4-11R features a red long rotary handle, red illumination and a black plastic bezel. Its maintained operating principle means the selected position remains engaged after the handle is released, making it suitable for machine-mode, circuit and process-state selection.

Designed for a 22 mm mounting hole, the M2SS4-11R provides IP66 front protection and NEMA 4X protection at the operator interface. The operator is supplied without a contact block and its illumination source is selected separately, allowing the completed assembly to be configured for the required control circuit. ABB order code 1SFA611203R1101 identifies this exact M2SS4-11R Selector Switch.

Maintained Rotary Selection with a Long Illuminated Handle

Maintained selector switches are used where an operator needs to choose a machine or process state that remains selected after the handle is released. The ABB M2SS4-11R provides two stable positions through a prominent long rotary handle, making it suitable for operating-mode selection, circuit selection and other two-state industrial control functions.

The red illuminated actuator supports visual identification and status indication, while the black plastic bezel integrates with ABB's modular pilot-device system. Compatible contact blocks and illumination components can be selected separately according to the electrical requirements of the application, providing flexibility 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.
