Why Choose the ABB M3SS3-11Y Selector Switch?
The ABB M3SS3-11Y is a versatile 3-position illuminated selector switch designed for industrial machinery, automation systems and electrical control panels. Part of ABB's Modular Plastic pilot device range, it features a yellow short-handle rotary actuator with a black plastic bezel, combining clear operator identification with compact 22 mm panel mounting.
The M3SS3-11Y combines maintained and momentary control in one operator. Its A and B positions are maintained, while the C position spring-returns to B when released. This arrangement is particularly useful where two stable operating selections are required alongside an additional temporary command.
Designed for demanding industrial installations, the M3SS3-11Y provides IP66 front protection and NEMA 4X protection. The yellow operator is suitable for illumination, while ABB's modular construction allows the required contact blocks and illumination components to be selected separately for the application.
Key Advantages
- Combines maintained and momentary control within one 3-position operator.
- A and B maintained positions provide stable operating selections.
- Spring return from C to B provides an additional temporary command.
- Yellow illuminated short handle provides clear visual identification and signalling capability.
- Compact 22 mm mounting format suits standard industrial control panels.
- IP66 front protection and NEMA 4X protection support demanding environments.

Combined Maintained and Spring-Return Control
The ABB M3SS3-11Y is designed for control schemes requiring both stable and temporary commands from a single operator. Positions A and B remain mechanically selected, allowing either state to stay active until deliberately changed, while position C provides a momentary command and automatically spring-returns to B when the handle is released.
This operating principle makes the selector useful for applications such as mode selection with an additional jog, reset or temporary machine command. Its yellow illuminated operator supports visual signalling, while ABB's modular pilot-device architecture allows compatible contact blocks and illumination components to be configured according to the required electrical control logic.
Typical Applications
- Industrial machinery control panels.
- Operating-mode selection with a temporary command.
- Machine positioning and jogging functions.
- Factory automation systems.
- Process control equipment.
- Production and assembly machinery.
- Conveying and material handling systems.
- OEM electrical and automation panels.
