1SFA611204R1006 ABB M2SS5-10B 2-Position Maintained Selector Switch

Why Choose the ABB M2SS5-10B Selector Switch?

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

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

Designed for a nominal 22.5 mm mounting hole, the M2SS5-10B provides IP66 front protection, operates from -25 to +70 °C and offers a mechanical durability of 0.5 million operations. The operator is supplied without a contact block, allowing compatible ABB modular contact blocks to be selected separately. ABB order code 1SFA611204R1006 identifies this exact M2SS5-10B 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 M2SS5-10B 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 black long handle and black plastic bezel provide a clear, coordinated operator interface, while ABB's modular pilot-device architecture allows compatible contact blocks to be selected according to the electrical switching requirements of the application. This modular approach provides 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.
