Why Choose the ABB M3SS7-21G Selector Switch?
The ABB M3SS7-21G is a robust 3-position illuminated selector switch actuator designed for reliable operator control in industrial machinery, automation systems and electrical control panels. Supplied under ABB order code 1SFA611216R2102, it forms part of ABB’s modular pilot device range and provides a durable, clearly visible interface for machine and process control.
The M3SS7-21G features a green illuminated short-handle actuator with a chrome-plastic bezel. Its three-position A-B-C operating arrangement uses maintained/momentary action, with positions B and C fixed and spring return from position A to position B. This configuration is particularly useful where two maintained selections are required together with a temporary command position.
Designed for 22 mm industrial pilot device applications, the M3SS7-21G uses ABB’s modular construction, allowing compatible contact blocks, holders and illumination components to be selected according to the electrical and signalling requirements of the application. Its compact short-handle format and illuminated operator make it suitable for machinery panels, operator stations and OEM automation equipment.

Reliable Operator Control for Industrial Machinery
Selector switches provide operators with a clear and intuitive method of selecting machine modes and issuing control commands. The ABB M3SS7-21G combines maintained B and C positions with a momentary A position that automatically returns to B, enabling control schemes where established operating selections are complemented by a temporary command.
ABB’s modular pilot device system allows the selector switch actuator, holder, contact blocks and illumination components to be configured according to the application. The green illuminated short-handle operator provides clear visual identification, while the chrome-plastic bezel offers a clean professional appearance for industrial control panels and operator stations.
Typical Applications
- Industrial machinery control panels.
- Machine mode and function selection.
- Momentary command and control functions.
- Factory automation systems.
- Motor and process control panels.
- Material handling and production machinery.
- OEM machinery and electrical control systems.
