Why Choose the ABB M3SS3-11L Selector Switch?
The ABB M3SS3-11L is a versatile 3-position illuminated selector switch designed for operator control and visual signalling in industrial machinery, automation systems and electrical control panels. Part of ABB's Modular Plastic pilot device range, it features a blue short-handle rotary actuator with a black plastic bezel for a compact and clearly identifiable operator interface.
The M3SS3-11L 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, making it suitable for applications requiring two stable selections together with an additional temporary command.
Designed for standard 22 mm pilot-device mounting, the M3SS3-11L provides IP66 front protection and NEMA 4X protection for demanding industrial environments. The blue operator is suitable for illumination, while compatible ABB contact blocks and illumination components can be selected separately to suit the required control circuit.
Key Advantages
- Combines maintained and momentary control within one 3-position selector.
- A and B maintained positions provide stable operating selections.

Combined Maintained and Spring-Return Control
The ABB M3SS3-11L is designed for control schemes requiring both stable and temporary commands from a single operator. Positions A and B remain mechanically selected, while position C provides a momentary command and automatically spring-returns to B when the operator releases the short rotary handle.
This operating principle makes the M3SS3-11L useful for applications such as operating-mode selection combined with a jog, reset or other temporary machine command. Its blue 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.
