1SFA611200R1104 ABB M2SS1-11L 2-Position Illuminated Maintained Selector Switch

Why Choose the ABB M2SS1-11L Selector Switch?

The ABB M2SS1-11L 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 M2SS1-11L features a blue short handle, black plastic bezel and B/C selector configuration. Its maintained operating principle means the selector remains in the chosen position after the operator releases the handle, making it suitable for functions where a selected operating state needs to remain active until deliberately changed.

Designed for ABB's 22 mm modular pilot-device system and a 22.5 mm panel cut-out, the M2SS1-11L provides IP66 front protection and is suitable for operating temperatures from -25 to +70 °C. Contact sets and the illuminating unit are ordered separately, allowing the completed switch assembly to be configured for the application. ABB order code 1SFA611200R1104 identifies this exact selector switch.

Key Advantages

• Two maintained selector positions provide positive selection between two control states.
• Illuminated design supports visual status indication when combined with the appropriate ABB illumination components.
• Blue short-handle actuator provides clear identification and convenient rotary operation.

Maintained Rotary Selection for Industrial Control Panels

Maintained selector switches are used when an operator needs to select a control state that remains active after the handle is released. The ABB M2SS1-11L provides two stable positions with a short blue handle, making it suitable for functions such as operating-mode selection, circuit selection and other two-state machine commands.

The illuminated design also enables visual indication 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 flexibility for machine builders and panel builders.

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.
