Why Choose the ABB M3SS2-11R Selector Switch?
The ABB M3SS2-11R is a robust 3-position momentary illuminated selector switch designed for dependable operator control in industrial machinery, automation systems and electrical control panels. As part of ABB’s modular pilot device range, it combines a short-handle actuator with spring-return operation and a highly visible red illuminated control element.
This selector switch uses a momentary A-B-C operating principle, with spring return from position A to B and from position C to B. This makes it particularly suitable for control functions where an operator temporarily selects either outer position and the actuator automatically returns to the central position when released.
The M3SS2-11R features a red illuminated short handle and black plastic bezel and is supplied without a contact block. Its modular construction allows compatible ABB contact blocks and illumination components to be selected according to the electrical and control requirements of the application.
Key Advantages
- Industrial 3-position momentary selector switch for operator control.
- Spring return from A to B and C to B for automatic centre return.
- Red illuminated short handle provides clear visual identification.
- Black plastic bezel for integration into industrial operator panels.
- Modular construction supports flexible selection of compatible contact components.
- Suitable for machinery, automation and industrial control applications.

Reliable Momentary Operator Control
Three-position momentary selector switches are useful where an operator needs to issue temporary commands in either direction from a defined centre position. The ABB M3SS2-11R automatically returns from either outer position to the central B position when released, helping provide intuitive control for machinery and industrial processes.
The modular design allows the selector switch operator to be combined with compatible ABB contact blocks and illumination components according to the control circuit. This flexibility makes it suitable for machine builders, panel builders and automation engineers developing customised operator interfaces.
Typical Applications
- Industrial automation control panels.
- Machine operator stations.
- Forward and reverse command functions.
- Jog and positioning controls.
- Production and processing machinery.
- Material handling equipment.
- OEM machinery and automation systems.
