Why Choose the ABB M3SS1-31L Selector Switch?
The ABB M3SS1-31L is a robust three-position maintained illuminated selector switch designed for industrial control panels, machinery and automation systems. Part of ABB's modular 22 mm pilot device range, it features a blue short-handle rotary actuator and chrome-metal bezel for clear manual selection and visual indication.
The M3SS1-31L provides three maintained positions, designated A, B and C, allowing the actuator to remain in the selected position until deliberately moved. This makes it suitable for operating-mode selection, machine-function control and other applications requiring three stable command positions.
Designed for standard 22 mm panel mounting, the M3SS1-31L is an illuminated modular selector switch operator. Holders, contact blocks and LED blocks are selected separately, allowing the operator to be configured to suit the required electrical control and indication function.
Key Advantages
- Three-position maintained selector switch for versatile industrial control.
- Three stable A, B and C positions remain selected until manually changed.
- Blue illuminated short-handle actuator combines manual selection with visual indication.
- Durable chrome-metal bezel provides a professional industrial operator interface.
- Standard 22 mm panel mounting simplifies integration into control stations.
- Modular construction allows compatible ABB contact and LED blocks to be selected for the application.

- Three-position maintained operation.
- A, B and C selector positions.
- Short-handle rotary actuator.
- Blue actuator colour.
- Illuminated selector switch design.
- Chrome-metal bezel.
- Supplied without holder, contact blocks or LED block.
- 22 mm modular pilot-device format.
- Individual operator weight of approximately 0.024 kg.
Reliable Three-Position Control for Industrial Machinery
Three-position selector switches provide operators with a straightforward interface for choosing between multiple machine states or control modes. The maintained action of the ABB M3SS1-31L keeps its short-handle actuator in the selected A, B or C position until another position is deliberately chosen, providing clear and predictable manual control.
The M3SS1-31L forms part of ABB's modular pilot-device system, allowing machine builders and panel designers to combine the illuminated operator with compatible holders, contact blocks and LED blocks. Its blue illuminated actuator and chrome-metal bezel make it particularly suitable for industrial operator interfaces where both control and visible status indication are required.
Typical Applications
- Industrial machinery control panels.
- Three-mode operating selection circuits.
- Manual / off / automatic control functions.
- Manufacturing and production equipment.
- Motor and process control stations.
- Material handling and conveyor systems.
- OEM machinery and industrial automation systems.
