Why Choose the ABB M3SS5-21G Selector Switch?
The ABB M3SS5-21G is a robust and versatile illuminated 3-position selector switch designed for industrial control panels, machinery and automation systems. As part of the ABB modular pilot devices range, it provides a clear and dependable operator interface for selecting machine functions and control modes.
This selector switch features a green long-handle actuator with a chrome-plastic bezel and an A-B-C selector arrangement. Its momentary operating mechanism provides spring return from positions A and C to the centre B position, making it suitable for control functions where the operator command should automatically return to the neutral centre position.
Designed for standard 22 mm control-panel mounting, the M3SS5-21G offers a rugged IP66 front protection rating and is suitable for illuminated applications. ABB's modular pilot-device construction allows the front operator to be combined with compatible contact blocks and illumination components to create application-specific control functions.

Reliable Operator Control for Industrial Machinery
Selector switches provide operators with a simple and clearly defined method of selecting machine functions, operating directions or control commands. The ABB M3SS5-21G uses three selector positions and a spring-return mechanism, allowing temporary commands to be initiated from either side of the centre position while automatically returning the handle to position B when released.
The modular ABB pilot-device platform enables the selector operator to be integrated with compatible contact blocks and illumination components according to the required control circuit. Its standard 22 mm mounting format makes it well suited to industrial control panels, operator stations and machine interfaces where reliable manual control and clear visual identification are required.
Typical Applications
- Industrial machinery control panels.
- Operator control stations and consoles.
- Forward/reverse or directional control functions.
- Manual machine command and mode-selection circuits.
- Production and process automation equipment.
- Material handling and conveyor systems.
- OEM machinery and electrical control assemblies.
