1SFA611204R1001 ABB M2SS5-10R 2-Position Maintained Selector Switch

Why Choose the ABB M2SS5-10R Selector Switch?

The ABB M2SS5-10R is a two-position maintained 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 prominent long rotary handle with maintained operation for dependable two-state control and selection functions.

The M2SS5-10R features a red long rotary handle, black plastic bezel and non-illuminated design. Its A/C maintained operating principle provides two stable selector positions, allowing the chosen operating state to remain selected after the handle is released.

Designed for a nominal 22.5 mm mounting hole, the M2SS5-10R provides IP66 front protection and operates across an ambient temperature range of -25 to +70 °C. The operator is supplied without a contact block, allowing compatible ABB modular contact components to be selected separately for the required control circuit. ABB order code 1SFA611204R1001 identifies this exact M2SS5-10R Selector Switch.

Maintained A/C Rotary Selection with a Long 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 M2SS5-10R provides two stable A/C 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 handle provides clear visual identification, while the black plastic bezel integrates with ABB's modular pilot-device system. Compatible contact blocks can be selected separately according to the electrical switching 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.
