Why Choose the ABB M3SS7-11L Selector Switch?
The ABB M3SS7-11L is a versatile three-position illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Part of ABB’s modular pilot device range, it features a blue short-handle actuator with a black plastic bezel, providing clear visual identification and dependable manual control.
The M3SS7-11L combines maintained and momentary operation. Positions B and C are maintained, while position A provides spring return to B. This arrangement allows the selector to provide both retained operating selection and a temporary control command from a single three-position operator.
ABB order code 1SFA611216R1104 identifies this exact M3SS7-11L selector switch. The illuminated operator uses the standard 22 mm modular mounting format and is supplied without a contact block or lamp, allowing compatible ABB contact blocks, holders and illumination components to be selected for the required control circuit.

Flexible Maintained and Momentary Machine Control
Selector switches provide operators with a straightforward interface for selecting machine modes and issuing control commands. The ABB M3SS7-11L combines maintained and spring-return functions, enabling a single operator to support both retained selections and temporary commands within an industrial control system.
Positions B and C remain selected until the operator deliberately moves the handle, while position A automatically returns to B when released. The illuminated blue actuator also provides enhanced visual identification, while ABB’s modular construction allows compatible contact blocks and illumination components to be configured for the application.
Typical Applications
- Industrial machine control panels.
- Factory automation equipment.
- Operating-mode selection systems.
- Manual machine control functions.
- Conveyors and material handling equipment.
- Production and process machinery.
- OEM machinery and electrical control systems.
