1SFA611200R1108 ABB M2SS1-11C 2-Position Illuminated Maintained Selector Switch

Why Choose the ABB M2SS1-11C Selector Switch?

The ABB M2SS1-11C is a two-position illuminated maintained selector switch operator designed for industrial machinery, control panels and operator stations. Part of ABB's modular pilot-device range, it provides positive rotary selection with a compact short-handle actuator for industrial command and signalling applications.

The M2SS1-11C features a clear short-handle actuator, black plastic bezel and B/C maintained selector configuration. Its maintained operating principle means the selector remains in the chosen position after the handle is released, making it suitable for applications where a selected machine or process state must remain active until deliberately changed.

Designed for ABB's 22 mm modular pilot-device system with a nominal 22.5 mm panel mounting hole, the M2SS1-11C provides IP66 front protection and operates across an ambient temperature range of -25 to +70 °C. Contact sets and the illuminating unit are ordered separately, allowing the completed selector assembly to be configured for the required control circuit. ABB order code 1SFA611200R1108 identifies this exact selector switch.

Key Advantages

• Two maintained selector positions provide positive selection between two control states.

Maintained Rotary Selection for Industrial Control Panels

Maintained selector switches are used when an operator needs to choose a control state that remains selected after the handle is released. The ABB M2SS1-11C provides two stable B/C positions with a compact clear short handle, making it suitable for operating-mode selection, circuit selection and other two-state machine commands.

The illuminated design enables visual signalling when the operator is combined with a suitable ABB illuminating unit. ABB's modular pilot-device architecture allows compatible holders, 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.
