Why Choose the ABB M3SS3-21G Selector Switch?
The ABB M3SS3-21G is a three-position maintained/momentary illuminated selector switch designed for industrial control panels, machinery and automation systems. Part of ABB's modular plastic pilot-device range, it features a green short-handle rotary actuator with a chrome-plastic bezel for clear operator control and visual indication.
The M3SS3-21G combines maintained and momentary functions across its three positions, with A and B fixed and spring return from C to B. This operating arrangement enables a maintained selection to be combined with a temporary command that automatically returns to the centre B position when the operator releases the handle.
Designed for standard 22 mm panel mounting, the M3SS3-21G is an illuminated modular operator supplied without a contact block. Its modular construction allows compatible ABB contact and illumination components to be selected according to the required electrical control function.
Key Advantages
- Combined maintained/momentary operation provides two control behaviours from one selector.
- A and B positions are fixed for maintained selection.
- Spring return from C to B provides a temporary command from the third position.
- Green illuminated short-handle actuator combines manual control with visual indication.
- Chrome-plastic bezel provides a clean industrial operator interface.
- IP66 front protection supports use in demanding industrial environments.
- Modular ABB construction allows compatible contact and illumination components to be selected for the application.

Flexible Maintained and Momentary Control for Industrial Machinery
Selector switches combining maintained and momentary positions allow different operator commands to be handled through a single control device. On the ABB M3SS3-21G, positions A and B remain fixed after selection, while position C automatically returns to B when released, providing a practical interface where both persistent and temporary commands are required.
The M3SS3-21G forms part of ABB's modular pilot-device system, allowing machine builders and panel designers to configure the illuminated operator with compatible control components. Its green short-handle actuator, chrome-plastic bezel and compact panel-mounting format provide a versatile operator interface for industrial machinery and automation equipment.
Typical Applications
- Industrial machinery control panels.
- Maintained mode selection with a temporary command function.
- Machine setup and operating controls.
- Jogging and temporary machine commands.
- Manufacturing and production equipment.
- Material handling and conveyor systems.
- OEM machinery and industrial automation systems.
