1SFA611200R3103 ABB M2SS1-31Y 2-Position Illuminated Maintained Selector Switch

Why Choose the ABB M2SS1-31Y Selector Switch?

The ABB M2SS1-31Y 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, visual indication and a durable metal bezel in a compact industrial operator.

The M2SS1-31Y features a yellow short-handle actuator with a chrome metal bezel. Its B/C maintained operating principle provides two stable selector positions, meaning the handle remains in the selected position after release until deliberately moved to the other position.

The illuminated design allows the selector to provide visual status indication when assembled with the appropriate ABB illumination components. The operator is supplied without a contact block, allowing the required switching arrangement to be configured using compatible ABB modular components. ABB order code 1SFA611200R3103 identifies this exact M2SS1-31Y Selector Switch within ABB product group 312001-Pilot Devices (Secrl).

Maintained Rotary Selection with Illuminated Indication

Maintained selector switches are suited to applications where an operator needs to select a machine or process state that remains active after the handle is released. The ABB M2SS1-31Y provides two stable B/C positions through a compact yellow short-handle actuator, making it suitable for operating-mode selection, circuit selection and other two-state industrial control functions.

The illuminated actuator adds visual signalling capability, while the chrome metal bezel provides a robust operator interface for industrial control panels. ABB's modular pilot-device architecture allows compatible contact blocks and illumination components to be selected according to the electrical requirements of the application, supporting flexible machine and panel design.

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.
