Why Choose the ABB M3SS7-11Y Selector Switch?
The ABB M3SS7-11Y is a robust 3-position maintained/momentary illuminated selector switch designed for operator control in industrial machinery, electrical control panels and automation systems. Part of the ABB Modular pilot device range, it features a yellow illuminated short-handle actuator and black plastic bezel for clear identification and dependable industrial operation.
The M3SS7-11Y combines maintained positions B and C with a momentary A position that spring-returns to B. This arrangement provides two stable selector positions together with a temporary command, making it useful where maintained mode selection and momentary control need to be combined within a single operator.
Designed for standard 22 mm control-panel mounting, the M3SS7-11Y provides a compact operator interface with IP66 front protection. Its yellow illuminated short handle enhances visual identification, while ABB's modular construction allows the required contact blocks and illumination components to be selected separately for the control circuit.
Key Advantages
- 3-position maintained/momentary operation combines stable and temporary control functions.
- Positions B and C are maintained for stable operating selections.
- Position A spring-returns to B for a temporary control command.
- Yellow illuminated short-handle actuator provides clear visual identification.
- Black plastic bezel provides a practical industrial panel finish.
- Standard 22 mm mounting and IP66 front protection support demanding control-panel applications.

Flexible Maintained and Momentary Machine Control
The ABB M3SS7-11Y combines maintained and spring-return functions within one three-position operator. Positions B and C remain selected after the handle is released, while position A provides a temporary command and automatically returns to B when released.
This operating arrangement is well suited to machinery where a stable operating selection must be combined with a momentary control command. ABB's modular architecture also allows compatible contact blocks and illumination components to be selected according to the electrical requirements of the machine or automation system.
Typical Applications
- Industrial machinery control panels.
- Machine operating-mode selection.
- Temporary machine command functions.
- Factory automation equipment.
- Material handling and conveyor systems.
- OEM machinery and operator control stations.
